Study on Vertical Permeability Coefficient of Unsaturated Zone in Renqiu Area Based on Double-ring Seepage Test
The permeability of vadose zone determines the transport speed of water between the surface,soil and underground,which is the key parameter for water resources evaluation.In order to verify the effect of double-ring seepage method and better study the permeability of vadose zone.Considering the influence factors of different geomorphic units and lithology,three groups of double-ring seepage tests were carried out for analysis and research.The results show that the double-ring seepage test results are close to reality,and it has the characteristics of simple operation,low price and high precision.The results can be used to study the basic data of water balance,reservoir and pit surface water infiltration in the follow-up work area.
