Subject : Hydrochemical identification and salinity problem of ground-water in Wadi Yalamlam basin, Western Saudi Arabia 
Document Language : English 
Abstract : Wadi Yalamlam, located in the western province of Saudi Arabia, lies within a typical arid to semi-arid area. Within its drainage area of about 1600km2, the ground-water of its shallow alluvial aquifer is relatively high in salinity. The present study integrates hydrochemical, hydrogeological, and recharge estimation analyses to identify the process/processes, that led to the aquifer salinity. The results of chemical analysis indicate that the ground-water salinity is highly variable and inconsistent along the course of the wadi. This variability is probably due to the local hydrogeological conditions and to the intensive evaporation of effluent surface irrigation water that led to the precipitation of evaporites, e.g. calcite, dolomite and gypsum, especially affecting the ground-water at shallow depths. The recharge rate of approximately 20mmyear1—also plays a role in determining the risk of ground-water salinity in this aquifer.
