Prediction of Soil Infiltration Rate Based on Silt and Clay Content of Soil

摘要

Soil infiltration rate is often determined using difficult and time consuming field tests, but it may be more suitable and economical to develop a method which predicts soil infiltration rate based on easily available physical properties of soil. Therefore, a relation between soil infiltration rate and some physical properties of soil is needed. In this study, for predicting soil infiltration rate (IN) based on silt content (SI) and clay content (CL) of soil, a two-variable linear regression model was suggested. The statistical results of study indicated that in order to predict soil infiltration rate based on silt content and clay content of soil the two-variable linear regression model IN = 37.87 - 0.315 SI - 0.527 CL with R~2 = 0.9042 can be strongly recommended.
