Mapping Hydrological Yields in The Ouaoumana River Basin: (November 2021-May 2022)

Abstract

In period of low water, the water table is the main supplier of water in all the catchment areas, the objective of this article is to study the hydrological yield in the River Basin Ouaoumana, which forms a tributary of the Oum Er-Rabia basin, in order to extract the most productive sub-basins during this period. The methodology adopted in this work is based on the method of quantitative assessment of water resources in order to measure flows during the period between (November 2021 and May 2022) and thus produce hydrometric data at several points along the watercourse. The main results obtained show that this basin suffers from the loss of large quantities of water, and this is linked to the agricultural activities that are concentrated on the banks of the river. The fragility of these water resources results from the imbalance between the capacity of the river and the needs of the growing population, which leads to a strong emptying of the aquifer and the reduction of surface water in the river.
