FLOOD ROUTING USING MUSKINGUM METHOD AND HEC-HMS MODELPayal Maharathi
Kinematic wave method was used for overland routing and Muskingum cunge method was applied for channel routing to describe the discharge on Narayani river and peak flow attenuation and dispersion observed in the direct runoff hydrograph. Channel cross section parameters are extracted using HEC- GeoRAS...
A physically based simplified discharge routing method, namely, the variable parameter Muskingum discharge-hydrograph (VPMD) routing method, having the capability of estimating the stage hydrographs simultaneously in channels with floodplains is presented herein. The upstream discharge hydrograph is routed ...
By analyzing the uniformizated data for flood forecast at the Luoshan Station,this paper provided correct measures for the factors that affecting the outflow of model and improved the method of checking and calculating the routing curve.It also researched the applicability of model to different flo...
the friction slope on the rising side of a hydrograph for a given flow, Q, may be quite different than for the recession side of the hydrograph for the same given flow, Q. This causes an effect known as hysteresis, which can introduce errors into the storage assumptions of this method. ...
Since the D8 method is applied for flow-direction determination in this study, the expression of the governing equation is essentially in a 1D (or quasi-2D) form. The continuity equation is written as∂y∂t+∂q∂x=iein which y is the water depth; ie is the rainfall excess rate,...
Reservoir Routing Reservoir acts storing water, and releasing it through the control structure with a certain delay Inflow hydrograph Outflow hydrograph Storage - Discharge Rel’n Outflow peaks are reduced Outflow timing is delayed Max Storage ...
The objective of this study is to quantify and delineate the spatial variability of channel losses over the contributing area of the upstream side of Wadi Al-Lith, in the western region of Saudi Arabia, by using Muskingum鈥揅unge flow routing method. HEC-HMS model was used here to simulate ...
In this research, using statistical data for the 903 km2 area Jooneghan-Farsan watershed at Chaharmahal & Bakhtiyari province, HEC-HMS model and the recorded flood hydrographs at the local hydrometric station, the effectiveness of the Muskingum model in the flood routing has been investigated. ...
MuskingumWe analyzed the characteristics of main karstic/non-karst reaches of the Lijiang River to uncover the causes behind different flood behaviors by providing a better understanding of the flood formation. Having 63 years of rainfall-runoff data and applying the HEC-HMS model, geo/hydrological ...
