Published: May 9, 2024

Abstract Groundwater is a valuable shared resource in the Moulouya Basin, but it has been decline due to recent years of low rainfall and rapid population growth. To support socio-economic development, there increased demand for this precious resource. This paper presents standard methodology delimiting potential groundwater zones using geographic information systems (GIS), an integrated analytical hierarchy process (AHP), remote sensing techniques. Seven parameters that monitor presence mobility groundwater, including drainage density, lithology, slope, precipitation, land use/land cover, distance river, lineament were incorporated into raster data model ArcGIS software. AHP-based expert knowledge was used prepare index assign weights thematic layers. The study classified area five varying potential: very high (26%), (51%), moderate (13%), poor (9%), (1%). accuracy validated by comparing Potential Zones map with from 96 wells boreholes across basin. validity results confirmed them specific yield aquifer area, yielding correlation coefficient ( R 2 ) 0.79. analysis revealed 89.5% situated zones, demonstrating reliability robustness employed approach. These findings can aid decision-making planning sustainable use water-stressed region.

Groundwater resources of the alluvial aquifer Ghiss Nekkor, which covers an area 100 km2, are main source domestic and agricultural freshwater supply in region Al Hoceima Morocco. Due to human activities (overexploitation, increase activity), this has become very sensitive chemical pollution. The principal objective current study is develop implement a calibration method assess, map, estimate vulnerability Nekkor pollution risk. In work, GIS-based DRASTIC model was used inherent contamination with seven standard hydrogeological parameters. Nitrate (NO3) electrical conductivity (EC) data were validate map. results map analysis show that contaminants varies from non-existent southwestern part plain (7.3% total area), high (14.5%). moderate central northeastern areas (26.9%), while it other (17.5%). Furthermore, most mainly concentrated near coastal strip on both sides River. these areas, NO3 EC values above maximum allowable limit World Health Organization. suggest can be effective tool for decision-makers concerned about managing groundwater sustainability.

In semi-arid regions such as the southwestern zone of Morocco, better management water resources is crucial due to frequent flooding phenomena. this context, use hydrological models becoming increasingly important, specifically in Aguenza watershed. A multitude are available make very efficient modeling, and from perspective, a comparative approach was adopted using two with different characteristics. Streamflow simulations were carried out continuously at daily time steps GR4J ATHYS (2002–2011). The latter used also simulate rainfall-runoff events (1984–2014). Simulation results distributed model compared those obtained by lumped “GR4J”, which shows disadvantages neglecting processes during study. However, remarkable improvement observed general appearance resulting hydrographs performance parameters after ((Calibration: NSE, RSR, PBIAS increased successively 8%, 6%, 45.2%); (Validation: 4%, 8.9%)). terms flood event simulations, good concordance between simulated discharge (NSEmedian = 0.7), indicating its great reliability for simulating data-scarce regions. This research highlights importance models, ATHYS, events.

Continuous-based comparison of the hydrological model is applied in different parts a watershed across world. However, little has been done on modeling Ethiopian watersheds, and nothing was to Robi watershed. This study aimed compare two (SWAT HEC-HMS) models for using monthly continuous data.
