New Methods for Modelling Dam-Break Wave
Recent developments in numerical analysis for hyperbolic equations have led to new methods which solve shallow water equations including complementary equations for hydraulic jumps. An...

Two-Dimensional Dam-Break Flow Simulation in a Sudden Enlargement
The paper presents the use of a two-dimensional depth averaged mathematical model for an unsteady dam-break flow simulation in a sudden enlargement. Continuity and two momentum equations...

Free surface flow modelling on a complex topography
The aim of this paper is to describe the different construction stages and the validation of a free surface flow model on a complex topography. This model is based on the two dimensional...

Strain Measurement on the Runner of a Hydroelectric Turbine
Twelve strain gages were installed on the 10-m-diameter runner of Unit G-23 (700 MW) at Grand Coulee Dam, Third Powerhouse. The gages were located on both the pressure and suction sides...

Non-Intrusive Experimental Setup for Inflatable Dam Models
A method which allows for a non-intrusive evaluation of the dynamic response of the inflatable dams under overflow and impounding water conditions is presented. The internal pressure variations...

Probable Maximum Flood Estimation for New and Existing Dams
Although various attempts have been made to streamline the procedures to determine PMF hydrographs for the design of new and rehabilitation of existing dams, there still remains a great...

Natural and Dam Break Flood Routing in Mountain Rivers
The accuracy of four one-dimensional flood routing methods is assessed for extreme floods in various mountain river settings. This preliminary assessment focusses on the prediction of...

Nonlinear Hydrodynamic Pressures on Arch Dam Faces
A finite difference method was used to calculate the nonlinear hydrodynamic pressures on the rigid arch dam faces. The arbitrary reservoir shapes were transformed to a regular cubic by...

An Improved Design of Fishways Under High Variation of Headwater
For the purpose of mitigating environmental impact, it is necessary to build fish passing facilities for fish migration when a dam is constructed on a river. But when the headwater variation...

Energy Dissipation for a RCC Stepped Spillway
A two-dimensional physical model study was used to quantify the kinetic energy dissipation of the steps in a roller compacted concrete (RCC) stepped spillway. The steps were effective...

1993 Mississippi Record Stages and Levee Failures
Record-setting stages, flooding duration, and multiple levee failures are distinguishing features of the Mississippi River 1993 flood. The peak stages reached at stations along the Illinois...

Bed Load Prediction in Steep Mountain Rivers
The characteristics of the stream channel morphologies in a very steep mountain ravine are explained by the data obtained through the longterm field observation. The bed load transportation...

Velocity Control Rings for RC Pipe on Steep Slopes
This paper discusses the use of internal concrete rings to reduce velocity and concrete erosion for reinforced concrete pipes on steep slopes in the Southern California area....

Management of Sediments on the Red River Waterway Project
The Red River is a large alluvial river system with the lower 280 miles currently being developed for shallow draft navigation. The navigation project entails construction of five locks...

Prediction of Accretion Below Muhuri Closure Dam in Bangladesh
An equation for prediction of siltation below a closure dam in the coastal area of Bangladesh has been developed using a diffusion equation of vertical transport of sediment. Applicability...

Investments in the Future
The projects that earned the 1994 Outstanding Civil Engineering Achievement Awards of Merit were improvements to the nations transportation and environmental infrastructures. On the outskirts...

Chicago's Waterfalls
The 1994 Outstanding Civil Engineering Achievement Award goes to successful implementation of an elegantly simple idea: aerate sluggish water by letting it fall through man-made waterfalls....

Alternatives for Overtopping Protection of Dams
Prepared by the Task Committee on Overtopping Protection of the Hydraulics Division of ASCE. This report summarizes the results of an inventory and...
