Abstract

Water Infiltration into the soil accounts as one of the processes that is considered by most of researchers moreover it has an important role in the water cycle. Due to the importance of infiltration phenomenon, scientists are continuously endeavoring to find an appropriate model for quantifying the infiltration rate. In the recent years, developing the simulation models related to the soil has been being increased. Also these models have been developed for evaluating of the problems concerned to environment and agriculture. The present study has been programmed for identifying the best INFILTRATION MODELS for two LAND USEs including rangelands and woodlands in DAVOOD RASHID WATERSHED located in Lorestan province. In this research, Measuring of infiltration rate was done by double rings methods and some INFILTRATION MODELS including Kostiacove, Philip, Horton, Soil Conservation Service (SCS) and Green Ampt were considered for estimating of infiltration rate. Results showed that all of the infiltration characteristics comprised of accumulated infiltration, ultimate infiltration rate, and average of infiltration rate, time to fixed infiltration rate and the slope of infiltration rate in the rangelands were less than woodland LAND USE. In addition, the best models for simulating of infiltration in rangeland and woodland LAND USEs have been chosen SCS and Philip models with coefficients of descriptive 0.967 and 0.993 respectively. Also, coefficients of efficiency relevant to two mentioned models were higher than other models and Horton model was selected as the weakest model in two investigated LAND USEs of rangeland and woodland.
