Webbrunoff data of small experiment areas. Then the relationship among runoff coefficient (C), curve number (CN) and average slope of areas (Slope) is analyzed using linear regression. The regression equation is C =− + CN + Slope0.20 0.0095( ) 0.0016( ) in which, C: runoff coefficient CN: SCS curve number Webbgroup are given in standard curve number tables (SCS, 1986). These values are applied only AMC-to II and in order to derive curve number values for AMC-I and III, the following correction factors need to be applied (Rao et al., 2010).If the antecedent moisture condition I (dry), the is curve number is adjusted down by using the following formula
