In the last decade, Morocco has experienced increased population, urban expansion, and improper environmental management, leading to a significant rise in waste production. This situation has exacerbated waste landfill issues, particularly in coastal areas such as Kenitra province, in the...

The aim of this study is to identify the main pollutants and evaluate the mechanisms of sediment transport from land to sea. This goal is justified by environmental pollution in the area associated with dredging and port activities. The objective is planned to be achieved by investigating the...

Coastal areas, vital for local communities, are subject to significant changes requiring rigorous management. This study focuses on assessing the evolution of the Atlantic coastline between Larache and Moulay Bousselham over a period of 60 years, with an emphasis on erosion and accretion risks....

This study presents a scientifically grounded delineation of protection perimeters for the Taïcha groundwater catchment field, located in the Maâmora aquifer (Gharb region, Morocco), in response to the lack of formally established protective measures and the growing risk of contamination from...

In arid and semi-arid regions, groundwater recharge is a key process controlling the sustainability of subsurface water resources. This study aims to assess and map the groundwater recharge potential of the Oued Cherrat watershed (Morocco) using an integrated approach combining Geographic Information Systems (GIS) and the Analytic Hierarchy Process (AHP). Six controlling factors were considered: lithology, lineament density, drainage network density, slope, land use/land cover derived from the Normalized Difference Vegetation Index (NDVI), and rainfall. The relative weights of these factors were determined through pairwise comparisons using the Saaty fundamental scale, and the consistency of the judgments was verified (CR < 0.1). The reclassified thematic layers were integrated into a GIS-based weighted overlay model to generate the groundwater recharge potential map. Five recharge classes were identified, ranging from very low to very high. The results show that areas with moderate recharge potential are the most widespread (approximately 37% of the watershed), while high and very high potential zones account for about 25% of the total area. These zones are mainly associated with permeable lithologies, high densities of structural discontinuities, gentle slopes, and low drainage density. In contrast, low to very low recharge potential areas are related to low-permeability formations, steep slopes, and dense drainage networks. The resulting recharge potential map provides a useful decision-support tool for sustainable groundwater management and for identifying priority areas for aquifer protection and artificial recharge planning in the Oued Cherrat watershed.

The Wadi Ouergha watershed faces significant challenges due to erosion, which directly impacts sedimentation rates and reduces the water storage capacity of the El Wahda dam, a crucial infrastructure for the region. This study aims to prioritize the sub-watersheds most vulnerable to erosion,...
