Modeling Critical Depth in Open Channels
This paper explores multiple critical depths. Reasons behind and characteristics of their occurrence are reviewed. A method to determine multiple critical depths is proposed for use in...

Confirmation of Seismic Safety at Stafford Dam
A critical aspect of the North Marin Water District's mission to maintain reliable water supply facilities and water service is periodic assessment and re-evaluation of the seismic safety...

Mapping Debris-Flow Hazard in Honolulu Using a DEM
A method for mapping hazard posed by debris flows has been developed and applied to an area near Honolulu, Hawaii. The method uses studies of past debris flows to characterize sites of...

Structural and Non-Structural Debris-Flow Countermeasures
Debris-flow can potentially occur for almost any torrents whose gradient is steeper than a given critical value and the frequency at which the debris-flow occurs depends on geological...

Modeled Hydraulic and Salt Transport Patterns in the Sacramento-San Joaquin Delta
Modeled hydraulic and salt transport patterns in the Sacramento-San Joaquin Delta have been summarized as the basis for detailed environmental assessment of proposed water management projects...

Variability in Solutions of Constrained Optimization Problems: Ocean Outfall Design Case
Uncertainty in optimization model resulting from parameter uncertainty has not been well studied in the hydraulics and water resources areas. To make valid decisions, knowledge of the...

The Seattle Forecast Model: A Tool for Water Resources Management in the Seattle Area
The Seattle Forecast Model, SEAFM, developed by Hydrocomp Inc. for the Seattle Water Department, is an interactive, graphic system for streamflow forecasting and reservoir analysis of...

Wastewater Treatment for Better Environment
Wastewaters from households, industries, and combined sewers are collected and transport to the treatment plant with the effluent commonly disposed of by dilution in rivers, lakes or estuaries....

Recent Developments in Safety Research from the Gas Research Institute
Recent developments in Safety Research, as supported by the Gas Research Institute (GRI), have consisted primarily of hardware-oriented applications to various gas industry safety operations....

Canadian Pavement Management Systems
A large portion of the investment in Canada's road system is in pavement structures. In the 1960's a coordinated national effort toward protecting the investment, through good pavement...

Pierce Transit's Experience with an Alternate Fuel Compressed Natural Gas January-December 1992
At the end of 1992, Pierce Transit's CNG fleet consisted of 30, 40-foot Orion buses, 19 ElDorado Buses, on GMC 'New Look' bus, one 1990 Chevy Celebrity, and one Collins Shuttle van. As...

The Financing Fray
Interview with two executives of the U.S. firm Morrison-Knudsen: Donn Smith, senior vice president of project finance at M-K's International Group, and Richard White, vice...

Dutch Globetrotting Pays Off
The Dutch have been doing business overseas for centuries, and Dutch consultants today continue the tradition. Several Dutch consulting firms are profiled. At Fugro-McClelland, N.V., Chief...

The Copper-Clad Library
The design vocabulary for the new Phoenix Central Library includes saddlebags, power bellies, tensegrity and corrugated siding. The saddlebags are copper-clad, steel-framed core structures...

Runoff As A Resource
Recent studies have shown that storm-water flows from urban and industrial areas typically contain significant quantities of the same pollutants found in wastewater and industrial discharges....

Letter from Oman
The bonanza days of the 1980s are over, but the oil-rich sultanate continues to be a rewarding, if challenging, market. Oil remains a focus of investment, and the government is planning...

Cost Effective Risk Allocation for Coastal Engineering Projects
Project participants will benefit significantly by routinely taking a more systematic, structured, and global view of risk than is sometimes done at present. Enhanced and broadened cognizance...

Geomechanics of Subsidence Due to Pumping of Groundwater
In this talk we describe a nonlinear theory for the classical problem of pumping of groundwater from a layered soil. The model soil system consists of three horizontal layers where a very...

Dynamic Response Analysis of Pile Foundations by Using Variational Calculus
Various approaches have been developed for the frequency-domain dynamic response analysis. The one proposed by M. Novak (1974) is simplest of all and yet produces the results very close...
