Infiltration Rates Variation and its Factors Analysis in Groundwater Reservoir Infiltration Field

Abstract:

The infiltration capacity is a decisive factor to ensure the effective operation of groundwater reservoir. This study analysis the infiltration capacity variation and its factors based on the data of infiltration test in Hutuo River Groundwater Reservoir. The results show that, there is a high infiltration rate in the alternative field, the infiltration rate is 3m/d, and decreased by 50% as 1.4m/d 6 days later; the contrast of soil permeability, vertical permeable rate of aerial zone, permeability of saturation zone between pre-test and post-test show that, the vertical permeable rate of aerial zone and permeability of saturation zone vary little, the descend of soil permeability is the main factor of the infiltration capacity decay.
