Calibration of Channel Roughness for Mahanadi River, (India) Using HEC-RAS Model
Hydrodynamic Model Calibration Simulation Flood Hydrograph Validation HEC-RAS
2013/3/19
Channel roughness is the most sensitive parameter in development of hydraulic model for flood forecasting and flood plane mapping. Hence, in the present study it is attempted to calibrate the channel ...
Modelling Open Channel Flows with Vegetation Using a Three-Dimensional Model
Hydrodynamic Turbulence Model Vegetation
2013/3/19
The effects of vegetation on the flow structure are investigated in this paper. In previous studies of modelling vegetated flows, two-equation turbulence models, such as the model, were often used. Ho...

2013/7/22
This paper presents a study of changes in the percentage of flow and the tide ebb prism in the North Channel of the Yangtze River Estuary. The analysis is based on data measured before and after the ...
WIDENING RATE OF ESTUARINE REGULATION AND ITS PRELIMINARY CALCULATION IN THE TRAINING LINE OF NORTH DEEP-CHANNEL OF THE CH ANGJIANG RIVER ESTUARY
Widening Rate Changjiang River Estuary Estuarine Regulation
2013/7/22
Based on the morphological relationships of rivers and estuaries, a formula for calculating widening rate of training works in estuaries has been derived. The widening rate is related to dimensions of...
MODEL STUDIES ON LOCAL SOCUR IN THE REGULATION PROJECT OF THE DEEP CHANNEL IN THE CHANGJIANG ESTUARY
Local scour Groins and jetty Model test Changjiang Estuary
2013/7/22
The local scour of the 1st-phase regulation project of the deep channel in the Changjiang Estuary were experimentally studied. The local-scour pits around head of the groins and the north jetty were s...
