ANALYSIS OF FLOW THROUGH INFILTRATION GALLERY

Abstract

Infiltration gallery is used to tap spring lines, increase the yield of dug wells. Sometimes, it's laid near to rivers and to collect the sub-surface flow of water, to collect storm water and runoff from non- road areas. The hydraulic of flow through infiltration gallery subjected to different depth of deposited material is studied. Effect of clogging on flow as well as hydraulic conductivity is described. Experiments are performed for varying water depth of 0 to 1.21 m and deposed layers of thickness 2.8 m to 2.15 m. It is observed that the flow rate reduces with the increase in deposited layer.
