Investigation of Long-Term Transport in Tanshui River Estuary, Taiwan
Publisher: American Society of Civil Engineers
Abstract: The net, long-term transport of materials in estuaries is governed primarily by the residual (or tidally averaged) circulation in the system. Knowledge of the residual circulation is essential for predicting the transport ...
Modeling of Flow Resistance in Mangrove Swamp at Mouth of Tidal Keelung River, Taiwan
Publisher: American Society of Civil Engineers
Abstract: The effects of mangrove trees on the flow field in a tidal estuary during high freshwater discharge events are investigated using a depth-averaged two-dimensional hydrodynamic model. The model is refined to include the ...
Dynamic Routing Model with Real-Time Roughness Updating for Flood Forecasting
Publisher: American Society of Civil Engineers
Abstract: A flood routing model with time-varying roughness updating was developed to simulate flows through natural channels based on the dynamic wave theory. Taking observed stages as the targets, a roughness updating technique ...
Procedure to Calibrate and Verify Numerical Models of Estuarine Hydrodynamics
Publisher: American Society of Civil Engineers
Abstract: In most hydrodynamic models, friction and turbulent diffusion/dispersion coefficients are the important calibration parameters affecting the calculation of surface elevation, velocity and salinity distribution. This paper ...
Modeling Salt Water Intrusion in Tanshui River Estuarine System—Case-Study Contrasting Now and Then
Publisher: American Society of Civil Engineers
Abstract: A vertical (laterally integrated) two-dimensional numerical model was applied to study the salt water intrusion in the Tanshui River estuarine system, Taiwan. The river system has experienced dramatic changes in the past ...
