“…In this study, we use the AHP model with 14 factors to map the potential groundwater areas (GWPA) in the Ifni basin. This approach has yielded satisfactory results in similar basins [4,5,9,11,19,22]. Our analysis of the factors, such as those used in previous studies [4,5,10,22], revealed that certain relevant factors, such as land use, the intersection between geological lineaments and the hydrographic network, the density of the nodes, and TPI, were not considered in the model.…”

“…This basin lies in the fractured and crystalline formations of the Ifni buttonhole, which is part of the western Anti-Atlas range [6,7]. In hydrological terms, it experiences heavy floods that bring significant volumes of surface water, which could be mobilized [8,9]. However, due to the low permeability of the geological formations, the water is not utilized and is instead lost in the Atlantic Ocean.…”

An assessment of potential groundwater areas in the Ifni basin, located in the western Anti-Atlas range of Morocco, was conducted based on a multicriteria analytical approach that integrated a set of geomorphological and hydroclimatic factors influencing the availability of this resource. This approach involved the use of geographic information systems (GIS) and hierarchical analytical process (AHP) models. Different factors were classified and weighted according to their contribution to and impact on groundwater reserves. Their normalized weights were evaluated using a pairwise comparison matrix. Four classes of potentiality emerged: very high, high, moderate, and low, occupying 15.22%, 20.17%, 30.96%, and 33.65%, respectively, of the basin’s area. A groundwater potential map (GWPA) was validated by comparison with data from 134 existing water points using a receiver operating characteristic (ROC) curve. The AUC was calculated at 80%, indicating the good predictive accuracy of the AHP method. These results will enable water operators to select favorable sites with a high groundwater potential.

“…In recent decades, the world has been affected by severe flooding, causing thousands of deaths, disruption of economic activities, and infrastructure destruction [2,5,6]. The flooded phenomena have been studied by several researchers, particularly in the development of theories, numerical models, and statistical methodologies, to describe flood behavior and space-time evolution [7][8][9].…”

“…In recent years, researchers have developed other techniques to predict the impact of high-intensity and short-duration floods, namely the Weights of evidence Model [20], Frequency Ratio [21], Index of Entropy [22], Random Forest [23], Logistic Regression [24], Artificial Neural Network [25], Index of Entropy [26], Analytical Hierarchy Process [27], and Flood Hazard Index (FHI) [8,28]. The latter, widely applied in several regions of the world, has shown its effectiveness.…”

During the last decade, climate change has generated extreme rainfall events triggering flash floods in short periods worldwide. The delimitation of flood zones by detailed mapping generally makes it possible to avoid human and economic losses, especially in regions at high risk of flooding. The Taguenit basin, located in southern Morocco, is a particular case. The mapping of the flood zones of this basin by the method of the Flood Hazard Index (FHI) in a GIS geographic information systems environment was based on the multi-criteria analysis, taking into consideration the seven parameters influencing these extreme phenomena, namely rainfall, slope, flow accumulation, drainage network density, distance from rivers, permeability, and land use. Average annual rainfall data for 37 years (1980 to 2016) was used in this study for floodplain mapping. A weight was calculated for each parameter using the Analytical Hierarchy Process (AHP) method. The combination of the maps of the different parameters made it possible to draw up a final map classified into five risk intervals: very high, high, moderate, lower and very lower presenting, respectively, 8.04%, 20.63%, 31.47%, 15.36%, and 24.50% of the area of the basin. The reliability of this method was tested by a Flood susceptibility analysis. The results generated by the Flood Hazard Index (FHI) model are similar to those of previous historical events. Realistic and applicable solutions have been proposed to minimize the impact of these floods as much as possible.
