Flood frequency analysis of homogeneous regions of Jhelum River Basin

Jhelum River is one of the major tributary of the Indus Basin River system. It drains the Northeast part of the Pakistan which includes the territory of occupied Kashmir, Azad Jammu and Kashmir, Northwest Frontier Province (NWFP) and Punjab. The major problem in the Jhelum River Basin is the scarcity of flow data. Therefore, under the circumstances of the lack of sufficient hydrological data, a regionalization technique was used to provide the estimate of the flow characteristics for unguaged catchments. The present study covers the Northeast part of the Pakistan up to the Mangla Dam. Maximum annual flow data for the selected fifteen gauging stations were assembled. Design flood for window (DFW) software for flood frequency analysis and MINITAB-11 were used for multiple linear regression analysis. The Gumbel distribution was found best fit by applying Chi-square test. Key words:
