Study of Environmental Impact of the Dam of Brenhas and Respective Irrigation Blocks

The Studyof Environmental Incidence has looked into the viability of different settings ofthe Hydroagricultural Perimeter of Brenhas due to various alternatives forwater sources.

The fact ofthe dam Brenhas (height: 15 m; basin: 28.6 km2; volume: 0.90 hm 3), be locatedin an area that is strongly conditioned by the geological point of view andwith reduced capacity of regulation and storage, implied the analysis ofalternatives for water sources (pumping stations in the Ardila river) whichalso focuses on the environmental component.

An analysiswas made with the depth and appropriate disposition for a study area of 1 960ha, targeting both the positive impacts, such as those that could potentiallycreate serious situations in environmental terms, in order to define solutionsthat can best meet the requirements technical, socio-economic and environmental.
