Análise de desempenho de drenos subterrâneos no Vale do Curú-CE.

Abstract

With the objective to analyses the subsurface drainage system, a research was conducted in the Curu Valley Experimental Station at Ceará. In the evaluation of the drainage performance, the entry resistance factor shows that the system was not working properly. The results also show that the water table flows towards the drains. It was also found that the Glover-Dumm approach best estimated the drain spacing.
