Estimation of Groundwater Recharge Using APLIS Method – Case Study of Bokoya Massif (Central Rif, Morocco)

Abstract

Considering the low annual precipitation of AL-Hoceima province, the groundwater resources, especially in Bo-koya, are one of the most critical water resources. Therefore, this study aims to estimate the amount of ground-water recharge into the Bokoya massif. For this purpose, the APLIS method is used in a geographical information environment for mapping the spatial distribution of groundwater recharge rates by combining five parameters: altitude, slope, lithology, infiltration, and soil. This study revealed that the recharge rate ranges between 9 and 76%, and the high rates (61–79%) are the most represented in the study area; this means that the region needs good groundwater management.
