EXPERIMENTAL STUDY ON WELL IRRIGATION IN CHAOBAI RIVER

This paper based on the subject of MI Huai Shun groundwater reservoir storage and water quality security research, analysis the ability of artificial recharge in the Chaobai River by measuring the attenuation of recharge volume and the variation of permeability coefficient after well irrigation test was carried out in Chaobai River. The test results show that the unit lifting recharge amount of well irrigation is 58.8～73.1m3(h.m)-1. There is a gradual attenuation phenomenon with the decay rate of well irrigation recharge 1.4m3(h.m)-1 on well irrigation. It is strong recharge ability and feasible technology that using water well recharge. The single well recharge amount can reached 300～350m3h-1. Analytical methods and test results can provide reference for the similar experimental research and engineering applications.
