A geo-spatial approach to perceive the groundwater regime of hard rock terrain- a case study from Morappur area, Dharmapuri district, South India

The goal of the present study is to identify the groundwater regime of Morappur area at Dharmapuri district, India. The study area covers an area of 410 sqkm. The area belongs to a hard rock terrain where the primary porosity is feeble and the secondary porosity offered by fracture, joints and shear zones etc, contributes to the groundwater regime. The availability of surface water resources is sparse and hence the groundwater repositories are intensely utilized. In the current study area, the availability of groundwater is limited due to scanty rainfall and poor recharge. The entire study area underlain by hard crystalline rocks of Archaean age, Charnokite and Hornblende epidote gneiss are the main rock types encountered in the area. The over exploitation of these resources more than the adequate recharge has resulted to decrease in the groundwater level. In this context, it is very much important to identify and understand the groundwater regime of this area for the better groundwater monitoring and conservation of this precious resource. Remote Sensing and GIS are playing a vital role in the advancement of hydro-geological studies. The use of conventional methods alone has its own limitations in comprehending the groundwater regime of the area. The integrated study using remote sensing, field studies together with GIS has helped to understand the role of structural, lithological and geomorphic units in controlling the groundwater occurrence and movement in the present study area. Various thematic maps were prepared from the satellite images and they were integrated and incorporated in a GIS platform along with collateral information to study the groundwater regime of Morappur area. The outcome of this study clearly shows the importance of the geospatial studies in identifying the role of satellite imageries and geospatial techniques to understand the groundwater regime of a hard rock terrain

Open-Source Software Application for Hydrogeological Delineation of Potential Groundwater Recharge Zones in the Singida Semi-Arid, Fractured Aquifer, Central Tanzania

This research article published by MDPI, 2020This study attempted to delineate and map potential groundwater recharge zones of the Singida, semi-arid, fractured crystalline basement aquifer using open source remote sensing and GIS software. Various thematic maps such as lithology/hydrogeology, soil, land-cover/use, slope, lineament density, drainage density and rainfall distribution were integrated in QGIS software. Vector input layers were rasterized and resampled using QGIS wrap projection function to make sure that the grid cells are of the same size. Reclassification using SAGA and GRASS reclass algorithms in QGIS was carried out to realign the factor classes in a consistent scale, and reclassification to a scale of 1 to 5 was carried out to harmonize the results. The study identified a number of potential areas for groundwater recharge, groundwater exploration, groundwater development and potential areas for artificial groundwater recharge. Potential groundwater recharge zones for the Singida semi-arid fractured aquifer are restricted to areas with high lineament density, cultivated areas, grassland and flat to gentle slopes. The potential of groundwater recharge is also observed in areas with low drainage density. The delineated zones provide a good understanding of the potential recharge zones, which are a starting point for recharge zone protection. This blended approach can be utilized for carrying out suitability analysis using the weighted overlay analysis approach. Areas designated good and very good are recommended for artificial recharging structures as an alternative technique for enhancing groundwater recharge through rainwater harvesting. This will help to augment groundwater storage in this semi-arid environment

A framework for loosely coupled components to automate municipal services (FLCCAMS)

Unifying and computerizing the procedures of municipal operations and maintenance is of great importance to municipalities as well as to ministries of local governments. On top of that, enhancing municipal e-services in terms of efficiency, quality, reusability, distribution and interoperability of these services; is a goal for most of municipalities.  Municipalities need to unify and computerize the procedures of maintenance and operations for their assets. This will eliminate the difficulties to prioritize the maintenance tasks; to let every task takes its turn fairly. In addition, this will speed up performing such maintenance and operation tasks, and will decrease the bugs appear after the maintenance is done. Therefore, the objective of this research work is to define, design and evaluate a conceptual framework for loosely coupled components to automate municipal services as well as unifying and computerizing maintenance and operations in local governments. The scope of this research covers roads and public buildings as the most important parts of municipal assets

Analysis of Recharge Potention in Upper Cisadane Watershed

ABSTRACT                Human disturbance such as land use changes, urbanization, and deforestation degrade Upper Cisadane Watershed. It also causes degradation of recharge area, decrease infiltration and increase runoff. The aims of this research were to (1) identify the criticality of recharge area; and (2) analyze the potential of water recharge in Upper Cisadane Watershed. The criticality of recharge area had been identified  refers to regulation of the Minister of Forestry, Republic of Indonesia Number: P.32/MENHUT-II/2009 by scoring and overlaying of slope, soil type, rainfall, and land use map. The amount of water recharge potential was predicted by the equation issued by IWACO and WASECO (1990).             The result showed that distribution of criticality of recharge area in Upper Cisadane Watershed in 2006, 2009, and 2013 were: (1) good: 24.7%, 24.7%, 23.6%; normal: 6.9%, 6.2%, 3.7%; (3) ranging critical: 17.9%, 17.8%, 19.4%, (4) rather critical: 25.0%, 24.9%, 30.7%; (5) critical: 23.9%, 24.5%, 22.0%; and (6) very critical:  1.9%, 2.0%, 0.7% respectively. The magnitude of the potential of water recharge on average in the recharge area was in good condition; 154.5 x 106 m3, normal; 33.9 x 106 m3, ranging critical; 94.6 x 106 m3, rather critical; 130.9 x 106 m3, critical; 98.2 x 106 m3, very critical; 6.2 x 106 m3. Upper Cisadane Watershed has a potential of annual water recharge was 511.7 x 106  to 569.2 x 106 m3/year or around 14% - 15.6%   of total rainfall, with an average change in the potential of water recharge from the simulation based on the condition of recharge area in 2006-2009 decreased -0.04%, in 2009-2013 decreased -3.2% and in 2006-2013 decreased -3.3%.Keywords: recharge area, infiltration, runoff, criticality

Multiclass spatial predictions of borehole yield in southern Mali by means of machine learning classifiers

Study region: Regions of Bamako, Kati and Kangaba, southwestern Mali Study focus: Machine learning-based mapping of borehole yield. Three algorithms were trained on an imbalanced multiclass database of boreholes, while twenty variables were used as predictors for borehole yield. All models returned balanced and geometric scores in the order of 0.80, with area under the receiver operating characteristic curve up to 0.87. Three main methodological conclusions are drawn: (a) The evaluation of different machine learning classifiers and various resampling strategies and the subsequent selection of the best performing ones is shown to be a good strategy in this type of studies; (b) ad hoc calibration tools, such as data on borehole success rates, provide an apt complement to standard machine learning metrics; and (c) a multiclass approach with an unbalanced database represents a greater challenge than predicting a bivariate outcome, but potentially results in a finer depiction of field conditions. New hydrological insights for the region: Alluvial sediments were found to be the most productive areas, while the Mandingue Plateau has the lowest groundwater potential. The piedmont areas showcase an intermediate groundwater prospect. Elevation, basement depth, slope and geology rank among the most important variables. Lower values of clay content, slopes and elevations, and higher values of basement depth and saturated thickness were linked to the most productive class

Advancing the use of geographic information systems, numerical and physical models for the planning of managed aquifer recharge schemes

Global change is a major threat to local groundwater resources. Climate change and population growth are factors that directly or indirectly augment the increasing uptake of groundwater resources. To outbalance the pressure on aquifers, managed aquifer recharge (MAR) schemes are increasingly being implemented. They enable the subsurface storage of surplus water for times of high demand. The complexity of MAR schemes makes their planning and implementation multifaceted and requires a comprehensive assessment of the local hydrogeological and hydrogeochemical conditions. Despite the fact that MAR is a widely used technique, its implementation is not well regulated and comprehensive planning and design guidelines are rare. The use of supporting tools, such as numerical and physical models or geographic information systems (GIS), is rising for MAR planning but their scope and requirements for application are rarely reflected in the available MAR guidelines. To depict the application potential and the advantages and disadvantages of the tools for surface infiltration MAR planning, this thesis comprises reviews on the past use of the tools as well as suggestions to improve their applicability for MAR planning. GIS is not mentioned by most MAR guidelines as a planning tool even though it is increasingly being used for MAR mapping. Through a review of GIS-based MAR suitability studies, this thesis shows that the MAR mapping process could be standardized by using the often-applied approach of constraint mapping, suitability mapping by using pairwise comparison for weight assignment and weighted linear combination as a decision rule, and a subsequent sensitivity analysis. Standardizing the methodology would increase the reliability and comparability of MAR maps due to the common methodological approach. Thus, the proposed standard methodology was incorporated into a web GIS that simplifies MAR mapping through a pre-defined workflow. Numerical models are widely used for the assessment of MAR schemes and are included into some MAR planning guidelines. However, only a few studies were found that utilized vadose zone models for the planning and design of MAR schemes. In this thesis, a review and a subsequent case study highlight that numerical modelling has many assets, such as monitoring network design or infiltration scenario planning, that make its utilization during the MAR planning phase worthwhile. Consequently, this study advocates the use of vadose zone models for MAR planning by showing their potential areas of application as well as their uncertainties that need to be regarded carefully during modelling. Physical models used for MAR planning are typically field or pilot sites, as some MAR legislation requests pilot sites as part of the preliminary assessment. Laboratory experiments are used less often and are mostly restricted to the analysis of very specific issues, such as clogging. This thesis takes on the issue of scaling laboratory results to the field scale by comparing results from three physical models of different scales and dimensionality. The results indicate that preferential flow paths, air entrapment and boundary influence limit the quantitative validity of laboratory experiments. The use of 3D tanks instead of 1D soil columns and the application of statistical indicators are means to increase the representativeness of laboratory measurements. Nevertheless, physical models have the potential to improve MAR planning in terms of detailed process assessment, scenario and sensitivity analyses. All tools discussed in this thesis have their merits for MAR scheme planning and should be advocated better in MAR guidelines by depicting their application potential, advantages and disadvantages. The information accumulated in this thesis is a step towards an advanced use of supporting tools for the planning and design of MAR schemes.:1 Introduction 1.1 Motivation 1.2 Objectives 1.3 Structure of the thesis 2 Status quo of the planning process of MAR schemes 2.1 Guidance documents on general MAR planning 2.2 Application of GIS, numerical and physical models for MAR planning 2.3 Planning of surface infiltration schemes 3 Using GIS for the planning of MAR schemes 3.1 Implications from GIS-MCDA studies for MAR mapping 3.2 Development of web tools for MAR suitability mapping 4 Using numerical models for the planning of MAR schemes 4.1 Review on the use of numerical models for the design and optimization of MAR schemes 4.2 Planning a small-scale MAR scheme through vadose zone modelling 5 Using physical models for the planning of MAR schemes 5.1 Design of the experimental study 5.2 Comparison of three different physical models for MAR planning 6 Discussion and research perspectives 7 Bibliography 8 AppendixDer globale Wandel stellt eine große Bedrohung für die lokalen Grundwasserressourcen dar. Klimawandel und Bevölkerungswachstum sind Faktoren, die, direkt oder indirekt, die zunehmende Nutzung von Grundwasserressourcen verstärken. Um diesen Druck auf die Grundwasserleiter auszugleichen, werden verstärkt Maßnahmen zur gezielten Grundwasserneubildung (managed aquifer recharge = MAR) durchgeführt. Dies ermöglicht die unterirdische Speicherung von überschüssigem Wasser für Zeiten hohen Bedarfs. Die Komplexität von MAR-Anlagen macht ihre Planung und Umsetzung kompliziert und erfordert eine umfassende Bewertung der lokalen hydrogeologischen und hydrogeochemischen Bedingungen. Trotz der weltweiten Implementierung von MAR ist dessen Planung wenig reguliert. Umfassende Planungs- und Gestaltungsrichtlinien sind rar. Der Einsatz unterstützender Werkzeuge, wie numerischer und physikalischer Modelle oder Geoinformationssysteme (GIS), nimmt bei der MAR-Planung zu, aber ihre Einsatzmöglichkeiten und ihre Anforderungen an die Anwendung spiegeln sich selten in den verfügbaren MAR-Richtlinien wider. Um das Anwendungspotential und die Vor- und Nachteile der Werkzeuge für die MAR-Planung darzustellen, wurden für diese Arbeit Recherchen über den bisherigen Einsatz der Werkzeuge durchgeführt. Zusätzlich wurden Vorschläge zur Erhöhung ihrer Anwendbarkeit für die MAR Planung gemacht. Der Schwerpunkt lag dabei auf Oberflächeninfiltrationsverfahren. GIS wird in keiner MAR-Richtlinie als Planungsinstrument erwähnt, obwohl es zunehmend für die MAR-Kartierung eingesetzt wird. Eine Recherche über GIS-basierte MAR-Eignungsstudien zeigte, dass der MAR-Kartierungsprozess standardisiert werden kann mittels des oft genutzten Ansatzes: initiales Ausschneiden von Gebieten, welche Restriktionen unterliegen, dem folgend die Eignungskartierung mittels Paarvergleich für die Wichtung der GIS-Karten und der gewichteten Linearkombination als Entscheidungsregel, sowie eine abschließende Sensitivitätsanalyse. Die Standardisierung der Methodik könnte die Zuverlässigkeit und Vergleichbarkeit von MAR-Karten aufgrund des gemeinsamen methodischen Ansatzes erhöhen. Daher wurde die standardisierte Methodik in ein Web-GIS integriert, das über einen definierten Workflow die MAR-Kartierung vereinfacht. Numerische Modelle werden häufig für die Beurteilung von MAR-Systemen verwendet und sind in einigen MAR-Planungsrichtlinien ausgewiesen. Es wurden jedoch nur wenige Studien gefunden, die die Modelle der ungesättigten Zone für die Planung und Gestaltung von MAR Standorten verwendeten. Die in dieser Arbeit durchgeführte Literaturrecherche und eine darauf aufbauende Fallstudie zeigen, dass die numerische Modellierung viele Vorteile bietet, wie z. B. beim Design eines Monitoring-Netzwerkes oder bei der Planung von Infiltrationsszenarien. Physikalische Modelle, die für die MAR-Planung verwendet werden, sind meist Feld- oder Pilotversuche, da einige MAR-Gesetzgebungen Pilotstandorte im Rahmen der Vorabbewertung verlangen. Laborexperimente werden seltener eingesetzt und beschränken sich meist auf die Analyse sehr spezifischer Fragestellungen, wie z.B. der Kolmatierung. Diese Arbeit beschäftigt sich mit der Skalierbarkeit von Laborergebnissen auf die Feldskale, indem sie Ergebnisse aus drei physikalischen Modellen verschiedener Maßstäbe und Dimensionen vergleicht. Die Ergebnisse deuten darauf hin, dass Makroporen, Lufteinschlüsse und der Einfluss der Randbedingungen die quantitative Aussagekraft von Laborversuchen einschränken. Der Einsatz von 3D-Tanks anstelle von 1D-Bodensäulen oder von statistischen Indikatoren ist ein Mittel zur Erhöhung der Repräsentativität von Labormessungen. Nichtsdestotrotz hat die Anwendung physikalischerModelle das Potenzial, die MAR-Planung in Bezug auf detaillierte Prozessbewertung, Szenarien und Sensitivitätsanalysen zu unterstützen. Alle beschriebenen Instrumente haben ihre Vorzüge bei der Bewertung von MAR-Anlagen und sollten in MAR-Richtlinien detaillierter berücksichtigt werden, indem ihr Anwendungspotenzial, ihre Vor- und ihre Nachteile dargestellt werden. Die für diese Arbeit zusammengestellten Informationen sind ein Schritt zur Förderung der beschriebenen Planungsinstrumente für die Planung und Gestaltung von MAR-Anlagen.:1 Introduction 1.1 Motivation 1.2 Objectives 1.3 Structure of the thesis 2 Status quo of the planning process of MAR schemes 2.1 Guidance documents on general MAR planning 2.2 Application of GIS, numerical and physical models for MAR planning 2.3 Planning of surface infiltration schemes 3 Using GIS for the planning of MAR schemes 3.1 Implications from GIS-MCDA studies for MAR mapping 3.2 Development of web tools for MAR suitability mapping 4 Using numerical models for the planning of MAR schemes 4.1 Review on the use of numerical models for the design and optimization of MAR schemes 4.2 Planning a small-scale MAR scheme through vadose zone modelling 5 Using physical models for the planning of MAR schemes 5.1 Design of the experimental study 5.2 Comparison of three different physical models for MAR planning 6 Discussion and research perspectives 7 Bibliography 8 Appendi

Characterization and simulation of nested groundwater flow systems in basins with contrasting climate and geology

A Thesis Submitted in Fulfillment of the Requirements for the Degree of Doctor of Philosophy in Hydrology and Water Resources Engineering of the Nelson Mandela African Institution of Science and TechnologyThe pattern, organization and hierarchy of nested groundwater flow systems, albeit complex, their understanding is very crucial for informed groundwater resources development and management. This study sought to characterize and simulate the impacts of varying climate and anthropogenic influences on the nested groundwater flow systems and the spatio-temporal association of nested groundwater flow systems, utilizing real field test cases of Singida semi- arid fractured aquifer and the Kimbiji coastal, humid sedimentary aquifer in Tanzania. Groundwater flow modelling and simulation of nested groundwater flow systems was carried out using the USGS finite difference modelling code (MODFLOW 6), utilizing ModelMuse version 5 as the Graphical User Interface (GUI). Hydrogeochemical and isotopic signature analyses complemented the modelling approach. The comparison of isotopic composition from borehole, rivers, lakes and rainfall showed that generally, boreholes in the Kimbiji aquifer and some in the Singida aquifer had depleted isotopic values and enriched isotopic values were in samples from open water bodies (e.g., rivers and lakes). The depletion was prominently so in the deep boreholes, indicating a limited influence of evaporation during groundwater recharge. Regional flow fluxes make up 74% of the total inflows into the Kimbiji coastal Neogene aquifer, and only 26% of the inflows are made up of the local flow systems. In the Singida aquifer, regional flow accounts for 56% of the total flux in the lower aquifer and makes 94% contribution to the total amount of groundwater inflow in the Singida aquifer. Only 6% of the groundwater storages comes from local recharge and other sources like lakes. The effect of land cover change dynamics on groundwater recharge has been more prominent in the Kimbiji aquifer, while the effect of climate varying (rainfall and temperature) featured more prominently in the Singida semi-arid aquifer. Dependence of local recharge on heavy rainfalls is one of the key features of the Singida aquifer, while local recharge in the Kimbiji aquifer is quasi-uniform, occurring at more or less similar rate, albeit decreasing with decreasing rainfall amounts and increasing surface temperature, and thus evapotranspiration. Local flow system fluxes were observed to be the main feeders for the upper unconfined aquifers in the two study areas, while regional flow systems are for the deep semi-confined aquifers, with appreciable exchanges of water as revealed by nested groundwater flow simulation. The study findings will contribute to various global, regional and local technical and policy-based efforts towards sustainable groundwater development and management, considering climate variability and non-climatic factors. This includes the contribution to Sustainable Development Goals (SDGs), particularly SDG on access to clean water and sanitatio

Evaluación de las zonas de recarga hídrica en relación a las formaciones vegetales en la parroquia Angochagua

Evaluar las zonas de recarga hídrica en relación a las formaciones vegetales en la parroquia Angochagua, provincia de Imbabura.La parroquia Angochagua se caracteriza por poseer fuentes hídricas superficiales y subterráneas en ecosistemas altoandinos de páramo, bosque y vegetación arbustiva. Sin embargo, la existencia de prácticas agrícolas y pecuarias sin las debidas medidas de conservación, crecimiento de la frontera agrícola e incendios forestales, han provocado la pérdida de cobertura vegetal y la reducción en la disponibilidad del recurso hídrico. El objetivo de este estudio fue evaluar las zonas de recarga hídrica en relación a las formaciones vegetales presentes en la parroquia Angochagua, a través de la metodología de Matus (2007). Donde, se identifica cartográficamente las zonas potenciales de recarga hídrica presentes en las diferentes formaciones vegetales en función a la pendiente, litología, tipo de suelo, uso de suelo y cobertura vegetal permanente. Para las áreas que presentan un potencial de recarga hídrica alto y muy alto se proponen lineamientos de manejo y conservación de los recursos naturales. De los resultados obtenidos las zonas de recarga con mayor superficie corresponden a recarga hídrica alta con 4001,15 ha presentes en las comunidades de La Rinconada y Zuleta y RH muy alta con 151,65 ha en la comunidad de Zuleta. Se determinó que el tipo de formación vegetal es uno de los factores de mayor incidencia en la posibilidad de recarga hídrica, los suelos cubiertos de bosque natural presentan una posibilidad de recarga hídrica alta, debido a que este tipo de bosque se caracteriza por tener una vegetación madura con sistema de raíces profundos, mayor densidad boscosa y alto contenido de materia orgánica, características que mejoran las propiedades del suelo e incrementan la capacidad de almacenamiento de agua

Strategi Pengelolaan Air Tanah Dangkal Di Sekitar TPA JABON Kabupaten Sidoarjo

Penelitian dilakukan di sekitar TPA Jabon, Kabupaten Sidoarjo. Kecamatan Jabon tidak memiliki akses distribusi air bersih seperti PDAM, sehingga air tanah dangkal (air sumur) merupakan kebutuhan air primer bagi mereka. Tujuan dari penelitian ini adalah pemetaan pola penyebaran kontaminan air tanah di sekitar TPA Jabon, menentukan strategi pengelolaan air tanah yang berkelanjutan di sekitar TPA, sehingga dapat menentukan pengolahan air tanah dangkal yang efisien. Analisa kualitas air tanah dangkal dilakukan pada 18 titik sampel dengan metode purposive sampling yang berjarak 500 mg/L sehingga dikategorikan sebagai air payau, hal ini karena daerah Timur lebih dekat dengan laut dibandingkan zona Selatan dan Barat. Parameter Fe pada semua sampel sumur masih dibawah baku mutu. Berdasarkan kontur persebaran, kontaminan air tanah dominan menuju ke arah timur dan selatan, hal ini sesuai dengan arah aliran air tanah. Strategi yang digunakan adalah penggunaan teknologi pengolahan yang mudah dan murah, pemanfaatan anggaran dana dan program pemerintah, mengadakan kegiatan penyuluhan terkait pengelolaan air tanah. Pengolahan yang dapat dilakukan adalah Filtrasi dengan ijuk, pasir halus, karbon aktif. ================================================================================================================================ This study was conducted around Jabon Landfill located in District Jabon, Sidoarjo. Jabon district doesn’t has access clean water distribution or clean water company like PDAM, so shallow groundwater is raw water primary in there. The purpose of this study are to Mapping the pattern distribution of groundwater contaminants around Jabon Landfill, determine sustainable groundwater management strategy around Landfill, so from the strategy can determine shallow groundwater treatment for consumption. Analysis of shallow groundwater quality at 18 sample points with a purposive sampling method less than 1000 meters from Jabon Landfill site. The parameters studied include TDS, Turbidity, Fe, Mn, Cl- and then compared with Minister of Health quality standards IV No 492 of 2010. Mapping is to determine the distribution of shallow ground water contaminant contour with Surfer 13. SWOT analysis is used to find management strategies of shallow groundwater around Jabon Landfill, so the well water treatment recommendations will be known. All samples for TDS and Turbidity parameter exceeded the quality standard. The highest concentration in well with distance 219 meter from East Zone are 2722 mg/L and 41,48 NTU. The high concentration of Mn is caused by seepage leachate, natural process and human activities. Well water from East Zone Landfill has a Chloride concentration > 500 mg/L so it’s categorized as brackish water, because the Eastern zone is near with sea compared with South and West zone. Fe parameters in all groundwater are still below the quality standard. Based on the distribution contour, groundwater contaminants heading to east and south, this is accordance with direction of groundwater flow. The strategy used are The use of easy and low budget process technology, utilization of budget funds and government programs, holding socialization activities related to groundwater management. Treatments shallow groundwater is filtration with fibers, fine sand, activated carbon
