Construction of dams on numerous rivers throughout the world must be the greatest achievement of human beings in river development and the greatest disturbance to stream ecology. The dams impact the riparian vegetation, invertebrates and fish in both the reservoir...
Abstract Within Integrated Water Resources Management, river impound-ment by large dams is rarely considered in terms of aridification and geo-morphological risks. Since transdisciplinary...
1 Ιαν 2007 · Based on data from three major wandering braided rivers in China, namely, the Yongdinghe, the Hanjiang and the Yellow Rivers, as well as a laboratory experimental study, this paper deals with...
9 Οκτ 2023 · European rivers are disconnected by more than one million man-made barriers that physically limit aquatic species migration and contribute to modification of freshwater habitats.
13 Απρ 2013 · Currently, most rivers worldwide have been intensively impounded. River damming becomes a big problem, not only in inducing the physical obstruction between upstream and downstream, but also in destroying the natural continuity of river.
The amount of water impounded by a dam differs greatly from one site to another. In run-of-the-river hydroelectric projects, the purpose of the dam is essentially to direct and control the flow of the stream and little water is impounded.
Impounded Rivers: Perspectives for Ecological Management. A comprehensive geographic analysis of the impact of dams and their associated reservoirs on rivers. Focuses on the river system downstream from the dam, including its floodplain, estuary or delta, and the near-shore coastal zone.
