Journal Title: Larhyss Journal - Year 2013, Vol 14, Issue 14
Abstract
The Hassan II dam included in the watershed Moulouya, is one of the largest Moroccan retaining dam with maximum storage capacity of 400 million cubic meters (Mm3). It controls a catchment area of 3300 km2 and ensures annual adjustment of 100 Mm3 speeds of Moulouya naturally irregular in its upstream part. It has as main purposes potable water, irrigation, protection of areas and dam against downstream flooding and siltation. Increased human activities upstream of the dam could lead to a degradation of the quality of that water. Our work aimed to follow the evolution of the physico-chemical quality of the water body via monthly samples and analysis of the main physico-chemical parameters. Sampling took place over the period September 2011 to August 2012. In light of the results obtained, the dam waters Hassan II exhibited moderately accentuated mineralization, they are hard and slightly alkaline. The lake can be classified as warm monomictic lakes. The concentrations of phosphorus compounds are low and the water body has not presented any period of anoxia.
