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...
Considerations in 2-D Modeling of Hydraulically Steep Flow
Simplifications in the equations used to describe shallow water flow lead to some difficulties in modeling supercritical flow. The hydrostatic assumption produces two significant differences...
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 Rest of the Best
Nominations for this year's Outstanding Civil Engineering Achievement Award ranged from a channel built to control flood waters to the construction of a wastewater pollution...
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...
Lessons Learned from the Design, Construction and Operation of Hydroelectric Facilities
A Thousand Points of Data
Significant cracking was discovered in a multistory parking garage shortly after construction. Was it safe to open? Based on visual inspection, a bridge was down-rated, with potential...
Northridge: Questioning Our Codes
The earthquake that struck Southern California at 4:31 A.M. Pacific Time on January 17, 1994 was responsible for 61 deaths, more than 9,000 injuries and $30 million in damages. From its...

Sludge Under Pressure
Few wastewater engineers ever have to deal with high-pressure pumping. In San Diego, however, city engineers will soon oversee a 100,000 ft long psi main that will transport sewage sludge...
Development of Mechanized Wet Mix Shotcrete Application in Norwegian Tunnelling Industry
From 1971 to 1980 wet mix shotcrete won the Norwegian market 100%. In the same period hand held spraying was replaced by hydraulic manipulators. From 1980 to 1986, steel fibre use increased...
Design of Shotcrete Linings at the Channel Tunnel
Shotcrete is one of the essential support elements of tunnels driven according to the principles of the New Austrian Tunnelling Method (NATM). Whereas originally the NATM was mainly based...
