Relationship between Infiltration Capacity and Topography, Soil Type and Land Use in Urban Area

Abstract

This study aims to make clear relationship between infiltration capacity and topography, soil type, and land use in urban areas. Infiltration capacities in urban areas are measured with a rainfall simulator. Topography of objective areas are upland, low land, and hilly land. Soil types of objective areas are sand, loam, and alluvial soil. Land uses are sports ground, bare land of temple or shrine, and garden of houses. Number of plots of infiltration test are 27. Nine plots are taken for each topography. The statistical analysis of final infiltration rates of 24 plots was done by Hayashi's quantification theiory 1.
