Title

DETERMINATION OF THE BEST INFILTRATION EQUATION FOR NEHMAT ABAD STATION OF (ISLAMIC AAZD UNIVERSITY OF TABRIZ) SOILS AND SENSITIVITY ANALYSIS OF INFILTRATION COEFFICIENTS TO INITIAL SOIL MOISTURE

Abstract

 Initial soil moisture has high effect on INFILTRATION characteristics, but it has not received much attention in measurement. This study was conducted to evaluate the initial soil moisture on INFILTRATION characteristics and SENSITIVITY ANALYSIS of Kostiakov, Philip, Horton, Modified Kostiokov and SCS INFILTRATION MODELs and to find out the best INFILTRATION MODEL for Nehmat Abad Agriculture Research Station soils in agriculture faculity of Tabriz Azad Islamic University. The INFILTRATION tests were carried out with double rings and 9 various initial soil moistures. The results showed that accumulation INFILTRATION and time to reach the final INFILTRATION reduces by increasing of initial soil moisture. Also Kostiokov and Philip methods were found the most suitable and SCS method unsuitable for the soils of the region. The coefficient of b in Kostiokov and Modified Kostiokov MODELs and S in Philip had low sensitivity to initial soil moisture but coefficients of C and A in Modified Kostiokov and Horton MODELs showed high sensitivity. Finally, results showed that Philip MODEL had least and Modified Kostiokov MODEL had the highest sensitivity to initial soil moisture variability.
