Research on environmental degradation in river branches areas

Abstract

The conservation of the ecological system of riverbeds is a necessity for ensuring the living conditions of the aquatic and riparian habitat. A number of special problems are imposed by the riverbed branches where an island is created. The research carried out on the lower course of the Moldova River, where the riverbed was artificially branched (Cordunarea, NeamţCounty) highlighted the need for a set of works on ecological restoration of the aquatic and riparian environment. The presence of economic disturbances in these areas(water capture)has led to significant morphological changes on the two arms of the Moldova River. The aquatic vegetation is almost completely degraded on the active arm of the river. The secondary arm of the riverbed has a variable flow over time, a situation that generates unviable living conditions for the habitat.
