SOME MODELING EQUATIONS INFILTRATION IN DIFFERENT LOCATIONS OF THE PROVINCE OF BABYLON

Abstract

Abstract : The cumulative infiltration was measured at Field 15 sites in the province of Babylon in the soils of different textuer , and with different content of organic material using a Double ring infiltrometer , to compared some equations to describe the infiltration at different areas of the province of Babylon, including experimental and other semi - experimental addition to the equations of the physical basis , to see the best compatibility of these equations , which is commensurate with the circumstances of the province of Babylon soils . The results showed consensus high to infiltration calculated from equations ( Kostiakov, 1932 ; Michael, 1978 ; Kirkham and Feng,1949 ; Horton, 1940 ; Kostiakov-Philip and Philip, 1957) with infiltration cumulative Field , while values showed infiltration calculated from equations (1980 Ghosh and Philip, 1957 & Young, 1968 (1) and Philip, 1957 & Young, 1968 (2) and Philip, 1969 and AL Doori.1986 and Hadi 1, 2005 and Talsms-Parlange, 1972 and Hadi 2, 2005) less compatible with the values of Field infiltration measured in the province .
