Risk-based Analysis of Major Rehabilitation of Hydraulic Structures Using REPAIR
This poster session presents a demonstration of a computer model developed by the Corps of Engineers to analyze investment proposals. The primary purpose of the model is evaluate investments...

Effects of Spatial Data Resolution and Subarea Size on a Distributed Runoff Model
Spatial data layers of elevation, land use, and soils for a small agricultural watershed in Pennsylvania were used to study the effect of resolution degradation of raster data on the output...

Maryland SHA's Procedure for Assessing Existing Bridges for Scour Vulnerability and for Rating Unknown Foundations
The Maryland State Highway Administration developed a recommended screening procedure for rating existing bridges for Item 113, Scour Critical Bridges, in the National Bridge Inventory...

Comparison of General vs. Multi Sector NPDES Storm Water Permits
In November 1990, in response to the 1987 amendments to the Clean Water Act, the EPA initiated the National Pollutant Discharge Elimination System (NPDES) storm water permitting program....

Two-Dimensional Modeling of River Dynamics for the Expansion of Clover Island, Kennewick, Washington
The Port of Kennewick, Washington, is proposing to redevelop Clover Island as a waterfront village concept. The island is located in the Columbia River between McNary and Priest Rapids...

Protection against Flooding: A New Delta Plan in the Netherlands
The Netherlands are situated on the delta of three of Europe's main rivers: the Rhine, the Meuse, and the Scheldt. As a result, the country has been able to develop into an important industrial...

3D Flow Structures?From Laboratory to Field Applications
One laboratory experiment and one field application have been modeled. For each one different sources of errors in the model results could be detected. It may be concluded that the applicability...

Mitigation Measures for Eroding Muddy Shores
A criterion for the stability of muddy coasts is proposed, accounting for bottom resistance, hydrodynarnic forcing and sediment supply. Although qualitative, this criterion provides a...

The Use of an Equivalent Porosity Method to Model Flow in Marshes
Two dimensional modeling of marshes under unsteady flow conditions often involves description of sections that alternately wet and dry. The equivalent porosity method (King and Roig, 1988;...

Data Analysis for Computer Modeling of Thermal Discharges
Assessment of the thermal discharge impact upon the environment and design of the appropriate discharge structure necessitate a range of data activities, from extensive field measurements,...

Dam Foundation Erosion Study: Pit 4 Scale Model Simulation
This paper describes the results of a sub task of the Dam Foundation Erosion Study, a cooperative research study by Reclamation, PG&E, Colorado State University, and Western Area...

On Silt Abrasion Erosion of Three Gorges Hydraulic Turbine in the Future
In this paper the basic parameters of Three Gorges hydraulic turbine have been reviewed and the operation characteristics of Three Gorges hydropower Station pointed out. Combined with...

Designing Concrete Culverts to Resist Scour Damage
Concrete culverts have been used for over 100 years. In this period, the main design concern centered on structural and hydraulic adequacy of the culvert. Scour is a relatively recent...

Study of Hydraulic Jump Lengths on Inclined Channel Beds
A hydraulic jump is generally used to dissipate kinetic energy of flow to protect man-made structures such as spillways, drop structures, and outlet works. It serves as a perfect location...

Evaluation of System Constant Volume Control
System constant volume control (SCVC) has been developed for optimal control of canal systems. The objective of system constant volume control is to maintain a reference storage (or target...

Tensioned Fabric Structures
A Practical Introduction
The objective of this publication is to provide basic information about the nature and characteristics of tensioned fabric structures. Its target audience includes architects, engineers,...

Recasting a Foundry (Available only in Structures Special Issue)
Even as the Philadelphia Naval Shipyard sails toward closure under the 1991 Base Realignment and Closure Law, work at the base foundry has accelerated since the 1980s. The foundry uses...

Retail Renovations (Available only in Structures Special Issue)
As stores change ownership and retailers establish outlets in older urban buildings, renovation and rebuilding of stores is a national trend--and a growing business niche for structural...

New Orleans Rolls the Dice (Available only in Structures Special Issue)
To compete with the gambling meccas of Las Vegas and Atlantic City, New Orleans recently took a gamble by erecting the world's largest casino building. With the structure...
