Statistical modeling of annual maximum precipitation in Oued El Gourzi Watershed, Algeria

Comparison of physical and statistical methods for estimating probable maximum precipitation in southwestern basins of Iran

The probable maximum precipitation (PMP) is the greatest depth of precipitation for a given duration that is physically possible over a given size storm area at a particular geographical location at a certain time of the year. In this study a physically based method was compared with a statistical procedure to calculate PMP in the southwest arid regions of Iran. In order to estimate PMP using a...

Performance evaluation of artificial neural networks in statistical downscaling of monthly precipitation (Case study: Minab watershed)

On ALADIN precipitation modeling and validation in an Alpine watershed

Highly resolved precipitation forecasts are necessary in many applications, especially in mountain meteorology and flash flood forecasts for smallto medium-sized alpine watersheds. Here we present precipitation forecasts simulated by the limited area model ALADIN applying different grid resolutions (1x = 10 km and 4 km). Target area of the investigations is the Alpine Ticino-Verzasca-Maggia wat...

Statistical modelling of annual maximum flows in Turkish rivers

The lognormal, Gumbel, smemax, log-Boughton, loglogistic, Pearson-3 and log-Pearson-3 distributions are applied to the annual flood peaks series longer than 21 observations of 112 unregulated natural streams in 23 major basins in Turkey. The parameters of most of those distributions are estimated by the methods of: (a) moments; (b) maximum likelihood; and (c) probability weighted moments. A det...

study of annual precipitation and its relaticr4ship with module in karaj watershed

in water resources projects knowledge of hydrological parameters is required. some of these parameters depend on the volume of water designed for those projects. in order to obtain a better yearly precipitation mean for karaj watershed, an attempt is made to homogenize the records of the various rainfall stations, using stations having longer recording periods. efforts are also made to determin...
