Constructing of control structures, like dams, change temporal and spatial unequal distribution of water ,and also play an effective role in reduce or eliminate of damage that caused by floods. So reservoir dam’s effect on floods discharges reduction must be determined. In this study the rain Information and flood hydrographs were used to check the flood routing for previous period of Maroon da...

On January 2019, the biggest flood in last decade struck Gowa and Makassar. The claimed enormous number of victims caused severe damage to many buildings; this can be anticipated by Flood Routing. This study aims analyze hydrograph, propagation time, determine inundation model during downstream Bili-Bili reservoir. research was conducted through three phases: delineation watershed using ArcGis ...

The most widely and popularly used method for prediction of flood hydrograph resulting from a known storm in a basin area use historical rainfallrunoff data and unit hydrographs derived from them. These procedures are highly unreliable due to the climatic and physical changes in the watershed and their implementation to ungauged catchments. The use of physically based rainfall-runoff estimation...

detention rockfill dams are an easy and common tool for flood control. due to their coarse pores, the flow in void spaces is turbulent and non-darcy. different relationships introduced by researchers are used to define the hydraulics of the flow within the rockfill materials. the present research is aimed at gaining a better understanding of the differ-ence among these relationships and the sou...

The support vector machine is used as a data mining technique to extract informative hydrologic data on the basis of a strong relationship between error tolerance and the number of support vectors. Hydrologic data of flash flood events in the Lan-Yang River basin in Taiwan were used for the case study. Various percentages (from 50% to 10%) of hydrologic data, including those for flood stage and...

Real-time correction models provide the possibility to reduce uncertainties in flood prediction. However, most traditional techniques cannot accurately capture many sources of uncertainty and provide a quantitative evaluation. To account for a wide variety of uncertainties in flood forecasts and overcome the limitations of stationary samples in a changing climate, a Bayesian theory based Self-a...

Abstract. With the increasing attention on environmental flow management for maintenance of habitat diversity and ecosystem health mountain gravel-bed rivers, much interest has been paid to how inter-flood low can affect river morphodynamics during subsequent flood events. Previous research found that antecedent conditioning lead an increase in critical shear stress a reduction sediment transpo...
