15 p, 283.9 KB Integrated environmental management of current reservoirs and regulated rivers / Palau, Antoni
At present, it is a common practice to identify reservoirs as the cause of negative effects on the regulated reaches of rivers. Reservoirs and regulated rivers maintain a close unidirectional relationship, downstream, so that the management of a reservoir, in addition to conditioning its own ecological characteristics, also determines the organization, operation and possibilities of the regulated river ecosystem.

En la actualidad, es bastante común identificar los embalses como causantes de efectos negativos sobre los tramos de río regulados. Los embalses y los ríos regulados guardan una relación intensa y unidireccional, río abajo, de modo que la forma de gestionar el embalse, además de condicionar sus propias características ecológicas, determina también la organización, el funcionamiento y las posibilidades del ecosistema fluvial regulado.
