Spatial distribution of soil under the influence of infiltration rate

Abstract

The infiltration capacity of soil influences the occurrence of overland flow. Further, the prediction of runoff has a crucial role in designing hydraulic structures as well as water resources planning and management. The study was conducted to determine infiltration rate by double ring infiltrometer, to compare the observed infiltration rates with the calculated infiltration rates, to study the suitability and validity of Horton’s equation and Kostiakov’s equation and to examine the spatial variability of infiltration rates of different agricultural plots. Puriya park, K. K. Wagh COAET, Nashik, was selected for the study area. Infiltration rate was measured by double ring infiltrometer. Further, it was observed that infiltration rate was higher in loamy sand soil than sandy loam for same condition. Soil without vegetation has lower infiltration rate as compare to soil with vegetation. Kostiakov’s equation was suitable than Horton for calculating the infiltration rate of sandy loam and loamy sand soil.
