Together with geological survey data, satellite imagery provides useful information for mapping. In this context, the aim of study is to map units Saka region, situated in northeast part Morocco based on Landsat Oli-8 and ASTER images. Specifically, aims to: (1) lithological facies volcanic zone, (2) discriminate different minerals using imagery, (3) validate results field observations maps. To do so, we used techniques achieve above objectives including color composition (CC), band ratio (BR), minimum noise fraction (MNF), principal component analysis (PCA), spectral angle mapper (SAM) classification. The obtained show good discrimination between facies, which confirmed by supervised classification images validated missions a scale 1/500,000. that area dominated Basaltic rocks, followed Trachy andesites then Hawaites. These rocks are encased quaternary sedimentary an abundance Quartz, Feldspar, Pyroxene, Amphibole minerals.

Seawater intrusion is one of the most severe problems confronting coastal aquifers. These aquifers are often considered significant freshwater sources, particularly in arid regions. The water resources mobilized at Al Hoceima (Northeastern Morocco) come from Ghiss-Nekkor aquifer and Abdelkarim El Khattabi dam. degradation groundwater quality probability marine has become a concern for communities. current study provides multidisciplinary research using hydrogeochemical statistical approaches to evaluate determine origin salinity this aquifer. Depending on direction flow, he results indicate that wells have total exceeding 2 g/L. dominant chemical facies encountered Na–Cl–Na–SO4 resulting rock-water interaction, meaning breakdown halite was predominant source mineralization. However, septic waste, irrigation inflows, locally seawater seem substantially influence area.

The watershed area of the Mangla Reservoir spans across Himalayan region India and Pakistan, primarily consisting Jhelum River basin. is rugged with highly elevated, hilly terrain relatively thin vegetation cover, which significantly increases river’s sediment output, especially during monsoon season, leading to a decline in reservoir’s storage capacity. This work assesses soil erosion risk (Azad Jammu Kashmir (AJ&K), Pakistan) using Revised Universal Soil Loss Equation (RUSLE). RUSLE components, including conservation support or control practice factor (P), erodibility (K), slope length steepness (LS), rainfall erosivity (R), crop cover (C), were integrated compute erosion. intensity maps generated by computing parameters, then physical factors such as units, elevation, slope, land uses/cover examine how these affect spatial patterns loss. 2021 data utilized (K) map was created world surface prepared Food Agriculture Organization (FAO).

Water is one of the fundamental resources economic prosperity, food security, human habitats, and driver many global phenomena, such as droughts, floods, contaminated water, disease, poverty, hunger. Therefore, its deterioration inadequate use lead to heavy impacts on environmental humans. Thus, we argue that address these challenges, can rely hydrological management strategies. The objective this study simulate quantify water balance components based a hydrologic model with available data at R’Dom watershed in Morocco. For purpose, used Soil Assessment Tool + (SWAT+) model. streamflow simulations were run monthly time step (from 2002 2016), during calibration period 2002–2009, coefficient determination (R2) Nash–Sutcliffe efficiency (NSE) values 0.84 0.70, respectively, 0.81 0.65, validation 2010–2016. results modeling revealed average annual precipitation was about 484 mm, out this, 5.75 mm came from development irrigation agricultural lands. evapotranspiration accounted for 72.28% input watershed, while surface runoff (surq_gen) 12.04%, 11.90% lost by lateral flow (latq), 4.14% groundwater recharge (perco). Our approach designed capture real image case study; zooming into other studies similar environments uncover situation highly recommended.

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%).
