Implementation of Distributed Hydrological Modeling in a Semi-Arid Mediterranean Catchment "Azzaba, Morocco"

The typical Mediterranean climate is marked at certain times of the year by sudden torrential rains causing high water flows, which leads to heavy flooding and hydroclimatic fluctuations due to a semi-arid climate, which explains why it is easy to understand the need for hydrological modeling for water resource management in these contexts. This work concerns the hydrological modeling of the Azzaba catchment area in Haut-Sebou "Morocco". In the first part of this work, a bibliographic synthesis is carried out to characterize certain factors (physical, geological and climatic), and a hydrological study is carried out by processing rainfall and hydrometric data from the used time periods. Ultimately, the use of the "ATHYS" platform is beginning to reproduce the flows at the Azzaba outlet, this model is really applicable in the semi-arid context based on several studies carried out on these contexts, since this model has to consider the chronological sequence of phenomena on one hand and the influence of the climatic and physical-hydrogeological parameters of the basin (humidity and soil exchange) on the other hand. Several criteria are used in this study to estimate the model's performance, the most common is Nash-Sutcliffe. After observation and analysis of the overall results, it can be concluded that the model reproduces flows in the Azzaba River watershed well, especially in event mode (mean Nash-Sutcliffe value of 0.71). The use of a historical meteorological time series to simulate flow using a daily time step gives average results with a Nash of 0.50, which strengthens the reliability of the ATHYS platform in the Mediterranean climate area

Fostering Sustainability through the Integration of Renewable Energy in … Fostering Sustainability through the Integration of Renewable Energy in an Agricultural Hydroponic Greenhouse

International audienceThis research explores the feasibility of integrating renewable energy sources, such as solar and wind, topower a hydroponic greenhouse. In this way, the latter’s energy autonomy is ensured. The study begins byevaluating the annual electricity consumption of the examined system. A renewable energy system capableof meeting its energy requirements throughout the year is also designed. The main objective is to assess theefficiency of two types of renewable energy sources, namely photovoltaic panels and wind turbines, and toimprove their integration within the agricultural chamber by implementing a model simulation. Twoscenarios were examined: the first one represents a photovoltaic power plant with storage, connected to thegrid, while the second scenario presents a wind power plant connected to the grid. This numerical analysisis supplemented by a one-year experimental study of a photovoltaic installation connected to the networkwith storage, which in turn is connected to the experimental device. To handle energy within the renewableenergy greenhouse, an energy management system was developed based on a fuzzy logic controller. Thissystem aims to maintain energy balance and ensure continuous power supply. The energy managementsystem optimizes energy flow to minimize consumption, reduce grid dependence, and improve overallsystem efficiency, resulting in cost savings and certain environmental benefits

Recycling Textile Waste to Enhance Building Thermal Insulation and Reduce Carbon Emissions: Experimentation and Model-Based Dynamic Assessment

By enhancing the thermal properties of cement-based building materials, energy consumption and carbon dioxide (CO2) emissions related to space conditioning in buildings can be alleviated. This study aims to present cement-based composites reinforced by textile fibers for application in building and construction. Several lightweight coating mortars were produced by partially replacing the sand in the mix with different percentages of textile waste. Mechanical and thermal characterizations of the reinforced cementitious composites were performed. The results showed that the thermal conductivity of cementitious compounds decreased as the proportion of reinforcing material in the mixture increased. In terms of mechanical properties, the textile slightly reduced the compressive strength of cementitious mortar, while it improved the flexural strength. A numerical study was then performed to derive the actual impact of these reinforced materials on the thermal behavior of a building element using COMSOL Multiphysics. Numerous configurations of walls coated with different mortar mixtures were studied. The results showed that coating both sides of a building wall with 20 mm of textile-reinforced mortar reduced the internal temperature by 1.5 °C. Thus, the application of these thermally improved mortars as coating mortars appears to be a relevant solution to enhance the thermal performance of buildings

Comparison of hydrological platforms in assessing rainfall-runoff behavior in a Mediterranean watershed of Northern Morocco

This research evaluates the applicability of different types of hydrological models to simulate discharge behavior scenarios in a northern Moroccan watershed, Oued Laou watershed (OLW). In this context, an improved understanding of the runoff mechanisms through hydrological modeling of the OLW can assist in the hazard risk management and facilitate the effective planning of water resources. For that end, a multitude of hydrological models were used to perform a very efficient modelling, and a comparative approach was adopted. Comparison of the models allowed the determination of potential sources of uncertainty in hydrological modelling of a subhumid watershed. Three models (ATelier Hydrologique Spatialisé (ATHYS), Hydrologic Modeling System (HEC-HMS), and Soil and Water Assessment Tool (SWAT)) with different characteristics were employed for a continuous modelling approach. The models were calibrated and validated using observed daily rainfall and streamflow data for 4 years (2004–2008) and 3 years (2009–2011), respectively. The multi criteria model comparison (R2 , NSE, RSR, and PBIAS) showed that all three models are capable of reproducing the observed flows. The SWAT model performed well over both periods (NSE = 0.76 for calibration), with an improvement in validation (NSE = 0.84). A good agreement was also observed in the HEC-HMS model outputs, with an approximately stable NSE of 0.77 and 0.78 for calibration and validation phases, respectively. The ATHYS model showed a NSE value of 0.67 during the calibration, with a decrease of 0.06 towards the validation period. The other performance criteria confirmed these findings. Additionally, results suggest that semi-distributed and conceptual hydrological models are particularly suitable for the OLW given their physical heterogeneity. Generally, the integration of these models may be suitable for water resources assessment in OLW.Gebiaw T Ayele received funding from Griffith Graduate Research School, Griffith University and covered the APC
