Earth Spillway Design Using SITES Software
The USDA Natural Resources Conservation Service has, recently released new software for the design and analysis of water resource structure sites. This software, SITES, is based on the...
Combined Flood Hazard Mitigation Techniques for Comprehensive Planning? The Saugus River Coastal Flood Risk Reduction Plan
The development of an alternative Coastal Flood Risic Reduction Plan for the Saugus River was initiated by the Executive Office of Environinental Affairs (EOEA) of Massachusetts in April...
Probabilistic Approach for Cancer Risk Assessment
Carcinogenic chemicals have entered ground water systems from surface spills and leaching from subsurface disposal sites. Of particular interest in this study was the contaminant tetrachioroethylene...
Canal Control and Automation for the Central District System
The Central Nebraska Public Power and Irrigation District system provides irrigation and hydropower benefits in south-central Nebraska. Because of its complexity, the system relies heavily...
Hydraulic Design of Subsurface Flow Wetlands
Although Subsurface Flow Wetlands (SFW) have received steadily increasing international attention during the past 10 to 15 years, comprehensive design criteria are not available for some...
Selection of the Form of Calculated Flood Hydrograph in Projecting Water Release Facilities
Traditionally, in evaluating hydraulic structures, river flood runoff hydrographs are determined by maximum flood water volume and discharge, duration of the flood and some other parameters,...
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...
River Meander Zones and Floodplain Reconnection
A natural disturbance regime concept is described for understanding ecosystem changes due to human activities. Re-establishment of river meander zones is proposed as an application of...
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...
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...
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
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...
