Sandbar Formation in Side-Diversion Channels
Prediction of sandbar formation in side-diversion channels is desirable in a wide range of river engineering problems. However, the mechanism by which they form is still not well understood...
Performance of Submerged Vanes for Control of Sediment in an Irrigation Canal
Removal of accumulated sediments from irrigation canals is necessary in order to maintain canal capacity. Removal of these sediments may be enhanced by directing and concentrating sediments...
An Improved Design of Excluding Sediment into River Intake Structures
The function of excluding sediment into river intake structures is usually achieved by the device of sluice ways. Although many sluice ways have been constructed and many formulas are...
Strengths and Weaknesses of Shallow Water Equations in Steep Open Channel Flow
The paper evaluates the strengths and weaknesses of shallow water equations in steep open channel flow. These equations, 1) St. Venant equations, 2) steep slope shallow water equations...
Theoretical study of unstable waves in the rapids of the river
This paper examines how the velocity distribution in free-surface flow affects the kinematic and dynamic velocities of disturbance waves on hillslopes or in high-gradient rivers, thereby...
Numerical Analysis of High Velocity Flow with Zero-Depth Line and Oblique Shock Wave in Steep Open-Channels
This paper deals with the numerical analysis of 2D steady high velocity flows with the zero - depth line and the oblique shock wave in steep open channels by means of the method of characteristics....
Numerical Experiments on Instability in Unsteady Flow Modeling
The problem of numerical instability in modeling unsteady open-channel flows is investigated using the technique of numerical experiments. The model is based on the one-dimensional de...
Investigation of an Anisotropic k-? Model
In this paper the eddy viscosity hypothesis is abandoned and explicit expressions of Reynolds stress are deduced directly from the transport equations. Anisotropic k and ? equations are...
Fortification of MMOC Models for Steep-Channel Flows
The Multimode Method of Characteristics(MMOC), designed to solve unsteady flows, is a new comprehensive scheme formulated by merging several individual characteristic schemes of the specified-time-interval...
Numerical Modelling and Laboratory Verification for the Turbulent Flow Field in the Branching Channel
Adopting the depth-averaged k-? turbulence model and using the finite volume method and SIMPLE procedure, the turbulent flow field in the branching channel is numerically solved and verified...
Thermo-Hydrodynamic Modelling of the Chicago Sanitary and Ship Canal
A one-dimensional numerical model of the Chicago Sanitary and Ship Canal and Lower Des Plaines River has been developed as a tool for assessment of the waterway's thermal response to actual...
Water Quality Enhancement Technology for River-Reservoir Systems
Water quality enhancement technology is applied to a wide variety of field conditions in surface waters including rivers, lakes and reservoir epiliminia, lake and reservoir hypolimnia,...

The Chien Tan Dragon Boat train will be the flagship station of the 87 km Taipei Rapid Transit System (RTS) in Taiwan, which consists of eight heavy rail lines, two medium-capacity lines...
Settlement Analysis
The U.S. Army Corps of Engineers Manual, Settlement Analysis, presents guidelines for calculation of vertical displacements and settlement of soil under shallow foundations. As soil is...
Reduction of Head Losses in Tunnels by Means of Shotcrete
Head losses in blasted rock tunnels conveying water to hydropower stations often significantly reduces the energy production in the plant. Typical values on the head losses in tunnels...
