Análise comparativa de dissipadores de energia e sua importância na prevenção da erosão.

Abstract

The efficiency of a draining project, since its conception until the effective execution directly is related to the importance that the designer gives to the measures of conservation and control in the watershed, becoming involved it the aspects related to the erosion and its processes of unfastening, has carried and deposition from sediments for the precipitation water. Detach the paper of the energy dissipator, hydraulical devices used is distinguished there to restitute or many times to delay the erosive forces of superficial waters of the precipitation for levels tolerated for the ground residual. A fast material of consultation to the designer is presented, with three of the main types of energy dissipators used currently, together with budget for the had comparison for the taking of decision of the best alternative not only of the hydraulical point of view, but jointly with the economic side.
