Resumo:
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.
