Theoretical expressions have been derived for obtaining optimum slope of graded check borders by using Horton's (1940) and Philip's (1954) infiltration functions for various border dimensions. Field evaluation of these expressions revealed that the theoretical expression involving Philip's infiltration function yields values of slope close to the field observed values as compared to the expression using Horton's infiltration function.
