Analysis of Hydrological Regime Variability from 1980 to 2014 of the Source of Ain Asserdoune in Beni Mellal, Morocco

Water and climate changeClimate change are regularly cited among the most crises that humanity will have to face in the coming decades. In fact, the links between the two issues are so close that we should perhaps see them as a single issue. In MoroccoMorocco, in this context of climate changeClimate change, water resourcesWater resources will be threatened and affected in many regions, with impactsImpacts on all areas of development (access to water, food security, health, etc.) while risks of water-related disasters will increase. Those who feel the impacts of these changes the most will be the most vulnerable first. On a regional scale, the Beni Mellal Atlas is known for its high groundwater potential and high unit productivity. Considered as the castle of MoroccoMorocco, it contains a number of springs that exceed the 54 gauged by the ABHOER (Agence du Bassin Hydraulique de l’Oued Oum Er-Rbia). TheSource of Ain Asserdoune (Morocco) source of Ain Asserdoune is a tourist site located in the center of MoroccoMorocco, at the regional level it belongs to the province of Beni Mellal and at the local level it covers the urban area and part of the municipality of Sidi Jaber. Its module is of the order of 1 m3/s, the maximum reaches 1.20 m3/s. The minimum is around 0.76 m3/s (1980–2014). The flowsFlows of this source are collected for the drinking water supply of the urban populations of the city of Beni Mellal, as well as the irrigation of all the fields which occupy the development basin of the source. The main objective of this scientific contribution is to relate the impact of these climate changesClimate change on the flowsFlows of the source of Ain AsserdouneSource of Ain Asserdoune (Morocco). To precisely define the characteristics of the flowsFlows of the source of Ain Asserdoune, we calculate the CMQ (Monthly flow coefficient) of all the chronicle studied (1980–2017) in order to extract all the information that can inform us about the variabilityVariability of the hydrological regimesHydrological regimes. Thus, we have made an analysis of all the situations of the hydrological regimes of the source of Ain AsserdouneSource of Ain Asserdoune (Morocco).
