Drainage Morphology Approach For Water Resources Development of Sub Watershed in Krishna Basin

The morphometric analysis of study area has been carried out using Arc GIS software. The study area covers 3035 sq.km. The drainage network was delineated using SOI topographical map of no. 47 K – 5, 6, 7, 8, 10, 11, 12, 47 L - 9 on the scale 1:50,000. Morphological characterized of the drainage line as appear in shape ,size, number, order, length, Dd, Sf, Rb, Fs, T, Rc are derived to trace its usefulness for surface development . The present study involves Geographic Information System (GIS) analysis technique to evaluate and compare linear relief and aerial morphometry of Yerala watershed of Krishna River. Yerala watershed is basically 7th order drainage and is mainly dendritic to sub dendritic. Drainage density and texture of the drainage basin is 6.89 km/km2, 18.60 respectively. The drainage frequency of Yerala watersheds is 1.96 where as the bifurcation ratio ranges from 2 to 11. Hence from the study it can be conclude that GIS technique proves to be competent tool in morphometric analysis

Groundwater Fluctuations in Sub Basin of Krishna River, Western Maharashtra, India

Water is the most important resource of a country and of the entire society as a whole since no life is possible without water. Water may occur in nature in liquid, solid as well as in gaseous form. All these forms of water are very useful to mankind. About 97% of the total available water on earth is contained in oceans, and is, hence, saline or salty in nature. The amount of fresh (sweet) water actually available is only about 3 % of the total quantity of water on the earth. Looking to the above, the reality is that there is essentially very less fresh water on the planet today and with development and population increase need for water increases day by day, so planning should be done for restoring the available water for the need of future generation. The proper conservation, maintenance, and careful use of water resources, along with developing additional storages, may considerably reduce the chances of water famines for future generations to come. In addition to these measures, we may have to find out means and ways for increasing the available usable water by developing artificial rain technology, easier ways to desalt sea water at cheaper rates, recharging the unconfined aquifers by constructing small check dams on small rivulets. Here, an attempt is made to study the ground water fluctuations in the Yerala river basin, located in Sangli and Satara district situated in Maharashtra state, India. Ground water table in the Yerala river basin decrease from 8 to 1.5 m Below Ground Level (BGL) during period of 2001 to 2010

SUSTAINABLE DEVELOPMENT PROPOSED IN KERA RIVER BASIN, WESTERN MAHARASHTRA, INDIA BASED ON MORPHOMETRIC ANALYSIS

Quantitative drainage network analysis & geomorphic evolution of the Sub-basin of Koyna River from Satara District of Maharashtra have been carried out. The various aspects of geomorphometric parameters such as, Drainage Density, Slope, Shape of the Basin, Bifurcation ratio, length ratios etc. along with the geological parameters gives the precise and objective overview about the watershed. This is the seasonal rain fed watershed, hence needs better management. Sustainable developments and management of the watershed is influenced by topography of the area and geomorphologic features. The generated geo-informatics can be readily used for decision-making. The manual estimation of geomorphic parameters is tedious and cumbersome process. However through this attempt of work, it has been found that integration of RS and GIS allows reliable, most accurate and updated database tool for handling special data, very useful in deriving geomorphometric parameters which are essential for planning of future infrastructural constructions, suggested here, for sustainable water resource development. Quantitative analysis and its interpretation of various drainage parameters enable qualitative evaluation of surface runoff, infiltration and susceptibility to erosion within the basin area. In the present study geomorphometric analysis has been carried out and the RS Data have been interpreted. Also, water availability with the help of flow accumulation study has been carried out. Based on this the locations of various water harvesting structures have been mapped, and also some related developmental activities have been suggested

SURFACE RUNOFF EVALUATION FOR AGRANI RIVER BASIN USING GEOSPATIAL TECHNIQUES

Nowadaysin water resources engineering watershed managementplays a vital role.Water harvesting structure based on management of water resources is essential to plan and protect the existingresources. Geographic Information System (GIS) and Remote Sensing (RS) techniques are mostly useful to achieve spatial and non-spatial database that signify the hydrologicfeatures of the watershed use as accuratelyas possible. In this study area of Agrani river basin, Upper Krishna basin, Western Maharashtra, India. The yearly rainfalldata of 7rain gauge stations (1998 –2015) together used to calculate the yearly runofffrom the watershed using Soil ConservationService –Curve Number (SCS –CN) method and Arc GIS tool. From the collected annually rainfall data for the years of 1998 to 2015 in the study area annualrunoff hasbeen calculated.The average rainfall is 466.63 mmrespectively and typical runoff for the year of 1998 to 2015 is 20.75 mm3 respectively
