  🌍 Surface Water–Groundwater Interactions in Sahelian Catchments: Insights from Hydrochemistry and Isotopes for Sustainable Water Quality Management Introduction 🌱 The Sahel, a semi-arid region stretching across Africa, is one of the most water-stressed areas on Earth. Rainfall is scarce, irregular, and highly seasonal, while populations depend heavily on both surface water and groundwater for drinking, agriculture, and livestock. Understanding how these two critical resources interact is essential for managing water sustainably. Surface water–groundwater interactions often determine the quantity and quality of available water. In Sahelian catchments, rivers, lakes, and ephemeral streams are closely linked to aquifers. Hydrochemistry and isotopic techniques have become powerful tools for unraveling these interactions and providing valuable insights into water quality management. This blog post explores how hydrochemistry and isotopes help us understand the dynamics of surface...
