      Estimate of the maximum probable precipitation for Alberta river basins [J. P Verschuren] on *FREE* shipping on qualifying : J. P Verschuren.   A generalized method to estimate the probable maximum precipitation (PMP) has been developed for catchments in eastern India (80° E, 18° N) by pooling together all the major rainstorms that have occurred in this area. The areal raindepths of these storms are normalized for factors such as storm dew point temperature, distance of the storm from the coast, Cited by: 7.

J. Hydrol., In this paper a version of a generalised method of estimating probable maximum precipitation (PMP) is applied to the catchments of four large dams in India. The value of a secure dam is high both in terms of human life and in economic terms.

The probable maximum precipitation (PMP) is defined as the highest precipitation (measured by a rain gauge) for a given period that is meteorologically reliably recorded in the rainfall station. Estimation of the PMP is very important, especially forAuthor: Sutopo Purwo Nugroho, Seno Adi.

Estimation of Peak Flood Discharge (PFD) at a desired location on a river is important for planning, design and management of hydraulic structures such as dams, bridges, barrages and design of storm water drainage systems.

However, studies based on rainfall data could be disturbed by the occurrence of missing data.

Therefore, studies of procedures and methods used to estimate missing data are essential. The most common spatial interpolation method used in estimating missing rainfall data is normal ratio (NR) weighting method (Chow et al, ). PROBABLE MAXIMUM PRECIPITATION IN BARCELONA Table I.
