Streamflow estimation at ungauged site using wavelet group method of data handling in Peninsular Malaysia

This study investigates the ability of wavelet group method (WGM) of data handling conjunction model in the estimation of flood quantiles in ungauged sites in Peninsular Malaysia. The conjunction method was obtained by combining two methods, discrete wavelet transform and group method of data handli...
