摘要：The study of Fe and Mn, key factors responsible for the deterioration of the water quality in an aquatic environment, has been undertaken to assess the mobility potential of these elements on the surface and bottom in SMBA Dam of Bouregreg basin. Indeed, the concentrations of Fe and Mn recorded during the campaigns of analyzes performed during 2004 (summer) and 2005 (winter) are generally spatial and temporal variables. The mean levels in our study are relatively low in surface and do not exceed the limit values of Fe (0.3 mg/l) and Mn (0.1 mg/l). Moreover, the highest values were found in the bottom sometimes exceeding standards limit and at the same time raising the difficulties o f water treatment. The analysis of Iron and Manganese in the dam SMBA and spatial and temporal taking into account the factors that determine their presence, show a double origin is linked to their release from the sediment deo xygenated, is due to the transfer of these two metals runoff cat chment Bouregreg to the dam
