Flood Design Discharge and Case Studies | SpringerLink
2017年11月4日 · Design discharge is the maximum flood that any hydraulic cross section allows to pass safely without inundation problems on the channel banks. Figure 7.1 indicates the bank-full level of a flood occurrence in a cross section, It is the amount of discharge that is calculated by taking into consideration the allowable and tolerable risk level.
Flood Discharge Prediction Based on Remote-Sensed …
2021年12月10日 · Based on the same research goal, this paper uses the rainfall and flow data of the target basin from 2010 to 2018 to establish a flood flow prediction model based on the fusion of spatiotemporal characteristics of machine learning and achieves satisfactory results in the prediction of flood peak and flood arrival time.
Adjustment of flood discharge capacity with varying boundary …
2021年11月5日 · It is of necessity to investigate the adjustment of flood discharge capacity in the Lower Yellow River (LYR) because of its profound importance in sediment transport and flood control decision-making, and additionally its magnitude is influenced by the channel and upstream boundary conditions, which have significantly varied with the ongoing ...
Reservoir Effects on Flood Peak Discharge at the Catchment Scale
2018年11月19日 · Using a parsimonious Instantaneous Unit Hydrograph-based model, we show that the flood peak attenuation is mainly controlled by three system characteristics: (1) the reservoir position along the river channel, (2) the spillway dimensions, quantified by the reservoir storage coefficient; and (3) the storage capacity.
Flood design discharge determination is very significant decision in water-related structure planning and construction. Water structures that require proper flood design discharge are canals, derivation tunnels, dams, culverts, bridges, and levees. Various scientific probability and statistical methods are used for determining the
A Method for Real-Time Measurement of the Vertical Vortex at Flood …
2024年8月28日 · In this study, ultrasonic sensors were used to measure the vertical vortex at flood discharge outlets in real time, and numerical simulations and model experiments were conducted. When a sound signal passes through a vortex, its propagation characteristics will change, which helps to determine the existence of the vortex.
A watershed-scale multi-approach assessment of design flood discharge ...
2024年3月1日 · Estimating flood peak discharge with USGS Regional Regression Equations (USGS-RREs) is a semi-empirical approach that accounts for various factors that influence flooding, such as the size of the drainage area, topography, the type of soil, and precipitation magnitude (e.g., average 24-hr maximum precipitation) in some cases (Vogel et al., 1999 ...
Hydraulic Reconstruction of Paleolandslide-Dammed Lake Outburst Flood …
1 天前 · The peak outburst flow discharge for the Xuelongnang landslide-dammed lake, estimated by the DL-Breach model, is 10,693.75 m 3 /s with a flood volume of 2.04 × 10 8 m 3, corresponding to the red point in Figure 14, which lies on the regression line. The physically based DL-Breach model, when compared with the empirical parametric model and ...
Joint Optimization of Water and Traffic Flow Discharge During Flood …
2024年8月15日 · More people can evacuate by delaying the flood's arrival at vulnerable regions through optimal placement and control of the water flow from the reservoirs. This paper proposes an optimization model to jointly control the reservoir system (in a water network) and the evacuation plan (in a transportation network) for maximizing the number of ...
