A dynamical model for orographic rainfall with particular reference to the Western Ghats is presented. The model assumes a saturated atmosphere with pseudo-adiabatic lapse rate and is based on linearized equations. The rainfall, as computed from the theoretical model, is in good agreement, both in intensity and in distribution, with the observed rainfall on the windward side of the mountain. Th...

A knowledge of rainfall distribution over a finite area is needed for small bydraulic structures design. Hydrologists have always been concerned about Depth- Area- Duration (DAD) for a specific storm in a watershed. An intense storm occurred on June 6, 1992 which claimed some lives in parts of Mashhad, Khorasan Province, Iran. Data of rainfall depth at 29 raingauge stations around the city and ...

The magnitude, rate, and extent of past and future East Asian monsoon (EAM) rainfall fluctuations remain unresolved. Here, late Pleistocene-Holocene EAM rainfall intensity is reconstructed using a well-dated northeastern China closed-basin lake area record located at the modern northwestern fringe of the EAM. The EAM intensity and northern extent alternated rapidly between wet and dry periods o...

We studied the temporal patterns of tracer throughput in the out ̄ow of large (30 cm diameter by 38 cm long) undisturbed cores from the Panola Mountain Research Watershed, Georgia. Tracer breakthrough was a€ected by soil structure and rainfall intensity. Two rainfall intensities (20 and 40 mm hr71) for separate Cl7 and Br7 amended solutions were applied to two cores (one extracted from a hillslo...

Sheet sediment transport was modelled by artificial neural networks (ANNs). A three-layer feed-forward artificial neural network structure was constructed and a back-propagation algorithm was used for the training of ANNs. Event-based, runoffdriven experimental sediment data were used for the training and testing of the ANNs. In training, data on slope and rainfall intensity were fed into the n...

quantitative measurement of meteorological drought, z score(z), rainfall anomaly (rai), standard precipitation (spi) indices and percent of normal precipitation (pnpi) based upon seasonal and annual rainfall data of the 15 meteorological stations of meteorological in hamedan province were used. also, in studying influences of drought on agriculture relative yield index of wheat was used. the re...

Benefiting from the high spatiotemporal resolution and near-global coverage, satellite-based precipitation products are applied in many research fields. However, the applications of these products may be limited due to lack of information on the uncertainties. To facilitate applications of these products, it is crucial to quantify and document their error characteristics. In this study, four sa...

This paper presents a new rainfall estimation method, EPSAT-SG which is a frame for method design. The first implementation has been carried out to meet the requirement of the AMMA database on a West African domain. The rainfall estimation relies on two intermediate products: a rainfall probability and a rainfall potential intensity. The first one is computed from MSG/SEVIRI by a feed forward n...
