Dam-break is a serious disaster resulting in severe damage to downstream communities. Therefore, analyzing the affected range and evolution process of dam-break floods advance valuable. However, difficulties challenges lie complexity breaking earth-rock dams, uncertainty floods, geographical variability. Given this, objective this study analyze characteristics flood evolution. The chooses Cheng...

The climate changes will be much more significant over the next 100 years and may lead to the heavy rainfall event. The heavy rainfall causes the flood hazard in the lowlands and geologic hazard in the mountains. Floods are also related to the changes in social economic conditions and land use. Recently, floods have been increasing due to rapid urbanization and human activity in the lowlands. T...

In order to provide parameters for sizing a damping reservoir, which was intended control the floods that occur in Ipiranga Stream basin, routine developed Visual Basic Applications (VBA) is used. From identification of most critical point flood, hydrological flow data are presented, estimated by dividing basin into sub-basins, using Rational method, resulting value higher than admissible one s...

Three geographic information system GIS -based distributed hydrological models were developed for flood simulation and forecasting in a subbasin of the Yellow River. A grid-and-topography-based distributed hydrological physical model, i.e., the GTOPMODEL model, is described that includes vegetation and root interception, evapotranspiration, and runoff generation via the saturation excess mechan...

Abstract Considering cost and time, the Muskingum method is most efficient flood routing technique. The existing models are only different in storage equation their efficiency depends on model type estimation of parameters. In this paper, nonlinear combined with a new lateral flow equation. Although includes five decision variables, done more accurately than previous studies. hybrid have 12 var...

In this paper, we unified two new algorithms, i.e., to selectively Bordercast the control packets in order to reduce the network load by limiting the number of control packets when ZRP searches for a new route. The second algorithm is proposed to optimize the performance of Query control mechanisms for the Zone Routing Protocol (ZRP) for mobile ad hoc networks for communication on an urban terr...
