| Abstract | Multiple regression analysis was used to investigate a
relationship for estimating runoff curve number (CN) in terms of
saturated hydraulic conductivity (Ks ) , average mean slope of the
.watershed (Sb), antecedent moisture condition (AMC) and vegetal cover
factor (Vc) taking into account nine watersheds in Thailand and two
Indian watersheds. Analysis showed no relationship based on the
available data . However, there was some correlation between CN and AMC
out of all the considered independent parameters used in the regression
analysis for a power type of relation. However, the parameter AMC alone
could not account sufficiently the variations in the CN values for any
of the considered watersheds. The main reason was probably the
non-representability of the rainfall data available, which affected the
estimation of CN as well as AMC. An additional reason might be that the
CN-AMC relationship was affected by other parameters also such as
varying saturated hydraulic conductivity during different storm events
etc. However, it was not feasible in the present study to estimate the
variations in these parameters during different storms and hence these
parameters could not be accounted in the analysis for establishing a
relationship for estimating the runoff curve number . |
