Abstract: The framework of the hydrological study for Western Nepal (part of the Nepal Irrigation Sector Project), prepared for the Institutional Development of Hydrology and Meteorology (DHM), Ministry of Science and Technology, includes the determination of the probable maximum precipitation (PMP) of 77 basins. The paper presents the study that was undertaken for the purpose of point and areal PMP determination in Western Nepal, including presentation of the Hershfield Method (1961) adapted to point PMP having durations longer than 24 hours. The analysis is based on rainfall data available in 109 rainfall stations in that part of Nepal during the period 1956-1998. Based on the point PMP depth values thus obtained, a map of equal PMP depth values is presented for Western Nepal.
