Climate and hydrological constraints on behavior iron and manganese in Smir dam (Tetouan Morocco) [Le climat et les contraintes hydrologiques sur le comportement du fer et du manganèse dans le barrage Smir (Tétouan Maroc)]

Iron and manganese are transition metals that can be complexed in water with organic or inorganic compounds and / or stay freely in response to biotic and abiotic conditions of the dam. their presence in the sources of water supply in general are influenced by natural and / or man. the approach to climate and hydrological constraints on the behavior of iron and manganese in dams in morocco was conducted by smir dam monitoring spatiotemporal physicochemical parameters. these results have allowed us to understand the behavior and speciation of these elements in the dam.
