    Probable maximum precipitation for 24 h duration over southeast Asian monsoon region - Selangor, Malaysia
    (Elsevier, 2001) M.N. Desa M.; A.B. Noriah; P.R. Rakhecha
    The probable maximum precipitation (PMP) for stations in Malaysia using Hershfield formula is routinely estimated as mean plus 15 standard deviations processed from yearly maximum rainfall values. The value of 15 as frequency factor is too high for a humid region such as Malaysia. In this paper, yearly maximum 1-day rainfall data of about 30-60 years for 33 stations in the region of Selangor, Malaysia, were analysed in an attempt to estimate PMP for 1-day duration based on an appropriate frequency factor for the first time.

    Probable maximum precipitation for 24-h duration over an equatorial region: Part 2-Johor, Malaysia
    (Elsevier, 2007) M.N. Desa M.; P.R. Rakhecha
    Probable maximum precipitation (PMP) is a characteristic of rainfall at a particular location that can be used in designing water impounding structures. The PMP for rainfall stations in Malaysia by Hershfield statistical method in earlier studies was estimated using a frequency factor of 15 which is the highest value in the world. The value of 15 as frequency was found to be too high for a humid country like Malaysia. The objective of this study therefore was to provide a fresh and reliable estimates of PMP in Malaysia using historical rainfall data.
