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...

Analyze the static simulation of the dam by using the strength reduction principle, get the stress, strain and displacement distribution rule and the corresponding safety factor in the water level change and rainfall infiltration are two working conditions of the reservoir’s retaining dam body respectively, get the displacement of the slip plane when the unstable failure happens on the dam, the...

The characteristics of rainfall-runoff relations were hypothesized for the study area using existing infonnation. These hypotheses were incorporated into the Hydrologic Simulation Program-FURmAN, and the rrodel was calibrated concurrently at 21 strearn-gage sites in the study area. The simulation e=ors after rrodel calibration were not large enough to reject the hypothesized characteristics. A ...

Abstract Rainfall-induced slope instabilities are ubiquitous in nature, but simulation of this type hazards with centrifuge modelling still poses difficulties. In paper, we introduce a rainfall device for initiating failure medium-sized centrifuge. This system is simple, robust and affordable. An array perforated hoses placed close above the model surface to generate raindrops. The intensity de...

T he growth of urban population, combined with an increase of extreme events due to climate changes call for a better understanding and representation of urban floods. Rainfall and infiltration are two important factors that affect the watershed response to a given precipitation event. In this paper, we evaluate the influence of the representation of infiltration and spatially variable rainfall...

Soil erosion is a global challenge, seriously threatening soil and water resources andenvironmental qualities. One of the important factors to consider in the process of runoffgeneration and soil erosion is the physical and chemical properties of soils under differentland-uses. The aim of this study is to estimate soil erosion and runoff in rangeland, rain-fedand abandoned rain-fed agriculture ...
