abstract obtaining reliable precipitation observations is important for hydrological simulations and weather forecasting. radar data can provide insight in the spatial variation of precipitation and can also detect large areas of rain and estimate rainfall rates. weather radar systems nearly always operate in s-, c- or x-band. since x-band systems require smaller antennas than those at c- or s-...

St. Armands Key, a barrier island located in western Sarasota County in Florida, has had a history of chronic flooding. It is relatively low and bowl-shaped and has experienced flooding caused by both excessively high tides and rainfall events. The existing stormwater drainage system on the Key includes one pump station and gravity drainage pipes, which are not adequate to meet the level of ser...

Within-event variability in rainfall intensity may affect pesticide leaching rates in soil, but most laboratory studies of pesticide leaching use a rainfall simulator operating at constant rainfall intensity, or cover the soil with ponded water. This is especially true in experiments where macropores are present--macroporous soils present experimental complexities enough without the added compl...

This study investigates the relationship between large-scale climate variability, rainfall oxygen isotopic composition (δO), and cave dripwater δO at Gunung Mulu and Gunung Buda National Parks in northern Borneo (4°N, 115°E) on intraseasonal to interannual timescales. A 3-yr timeseries of rainfall δO contains prominent seasonal and interannual variability. The seasonal cycle in rainfall δO is d...

The aim of the project is the development of an Early Warning system for flood events based on precipitation analysis and related to historical flooded area detection.The recently change of Humanitarian International Agencies in the way of approaching the emergency preparedness has lead UN (United Nations) system to create a tightened collaboration with different research centers, where ITHACA ...

A long-lived heavy precipitation area was observed along the southwest coast of Taiwan from 13 to 18 June 2008 during the Terrain-Influenced Monsoon Rainfall Experiment (TiMREX). Rainfall amounts exceeded 500mm along portions of the coast, and the coastal plains experienced severe flooding. The precipitation systems were influenced by blocking effects, as the southerly moist monsoon flow imping...

Information about streamflow characteristics e.g. runoff-rainfall (R/O) ratio, rate and timing of flow, surface and subsurface drainage (SSD), and response time to rainfall events is necessary to accurately simulate fluxes and for designing best management practices (BMPs). Unfortunately, those data are scarce in the southeastern Atlantic coastal plain, a highly urbanizing region characterized ...

Permeable pavements and similar stormwater control devices have not been exploited in the UK, in part because their adoption has been hindered by a lack of detailed knowledge of their hydrological performance. This paper describes a research programme that produced detailed information on the hydrological behaviour of a car park surface. The study involved the construction of full-scale permeab...

Background: Three groups of factors related to topography, geology and hydrology have influence on the triggering of shallow landslides in soil material. In this paper a single representative factor (T-factor) for the topography is proposed, which can be used to define threshold values for the possibility of shallow soil slides. This study was carried out in the Dayi area, Guizhou Province, Chi...
