How to manage the cumulative flood safety of catchment dams
Dam safety is a significant issue being taken seriously worldwide. However, in Australia, although much attention is being devoted to the mediumto large-scale dams, minimal attention is being paid to the serious potential problems associated with smaller dams, particularly the potential cumulative safety threats they pose in catchments. This paper establishes the significance of this problem an...
متن کاملReal Time Flood Forecasting - Indian Experiences
The real time flood forecasting is one of the most effective nonstructural measures for flood management. For formulating the flood forecast in the real time, the observed meteorological and flow data are transmitted to the forecasting station through the different means of data communication which include telephone, wireless and network of telemetry stations etc. The collected meteorological a...
متن کاملField experiments on coarse-sediment displacement upstream of flood mitigation dams
This study deals with the transport behavior of the coarse-sediment at Masudagawa flood mitigation dam (FMD), Japan. Radio frequency identification system (RFID) was used to trace the displacement of the IC tagged particles following major flood events since June 2011. Through this, the relationship between recovery rate of the tagged particles and distribution of shear stress over the FMD bed ...
متن کاملPush-over analysis of concrete gravity dams due to flood inflow
This study numerically predicts the failure scenario of a cracked concrete gravity dam through a push-over nonlinear analysis. The mixed-mode Linear Elastic Fracture Mechanics (LEFM) was employed using the extended finite element method (XFEM). The dam base was considered to be fully fixed without any foundation effects. The hydrostatic pressure on the dam's upstream face was increased incremen...
متن کاملThe Impact of Dams on Flood Flows in the United States
Natural flood regimes provide a wide array of important ecological functions. Our goal is to assess the hydrologic impact of dams on flood flows throughout the United States. Regional regression models of the median annual 1-day maximum flow were developed as a function of natural watershed characteristics, dam storage, and population density. Most of the regressions have adjusted R2 values in ...
