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 Bokoya, are one of the most critical water resources. Therefore, this study aims to estimate the amount of groundwater 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.
