The Infiltration Characteristics of Soil Mixed with Water Absorbant High Polymer

Abstract

Water holding substances mixed in soils affect the infiltration characteristics of soils, thus rainfall-runoff process changes. Therefore, the headwaters conservation and the flood-prevention may be controlled.
The laboratory experiments with the artificial rainfall, have been made by a lysimeter with diameter φ 200.
The effect of mixture ratio of soil and water absorbent high polymer was examined. The soil parameters of each mixture case are identificated by the analysis of hydrograph data.
