Application of collecter well to replace the conventional method in the northern mountainous area

Abstract

The solution of using a collector well was investigated to take additional water, overcome the weaknesses of the conventional weir that are prone to sediment accumulation intake structures of a weir, especially at the location where weir is not needed. The solution was considered using a laboratory model at Hydraulic Construction Institute - Vietnam Academy for Water Resources. The results of model research and construction of a pilot project in Muong Lan commune, Muong Ang district, Dien Bien province show that collector well can collect water over 31 l/s ensuring water supply for more than 20 ha of rice field.
