With the objective of investigating the hydrological homogeneity of India's hydrometeorological subzone 3-a and identification of a suitable frequency distribution for it, a regional flood frequency analysis has been carried out using the index flood procedure and the L-moments. Based on analysis of flood data at 12 gauged sites, the Mahi-Sabarmati basin is shown to be hydrologically homogeneous and follows the generalized normal distribution. Regional curve developed based on the analysis has been recommended for carrying out flood frequency analysis at both gauged and ungauged sites in this region.
