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 Webb2 feb. 2024 · The following table was adapted from Hydrologic Analysis and Design (4th Edition) (McCuen, 2024).
