Validade de equações de drenagem para drenos de feixes de bambu simples, em condições de campo.

Abstract

The water table depth, was monitoring between bamboo drain and the flow measuring, to avaliate his performance in drainage systems. Bamboo drain, were spaced in 10, 20 and 40 m, with declivity of 3 and 6%. The Glover-Dumm equation presented the best performance to the 10 m space. But, the 20 m spacement was adjusted too. For that, the 20 m spacement, shown the more adjusted economical and technical.
