Grade-Control Structures for Salt River Channelization
Soil cement grade-control structures have been designed and constructed in conjunction with channelization projects along the Salt River in Phoenix, Arizona. The structures were designed...
System Downstream Control for On-Demand Irrigation Canals
A nonlinear programming (NLP) Model has been developed to assist downstream control for optimal control of canal systems, called system downstream control (SDC). The objective of system...
Grade Control Structures for Pipeline Crossings in the Arid Southwest
Pipeline crossings at streams, rivers, and washes are at risk due to bed and bank erosion in the river environment. Buried pipelines may be exposed in the channel bottom by scour of bed...
Successful Implementation of Grouted Boulder Grade Control Structures on Drainageways in the Denver Metropolitan Area
This paper describes the development of design guidelines for the Grouted Sloping Boulder drop structure as an alternative for the sloping riprap drop structure. A number of partial failures...
Comparison of Water Backwash and Brush Cleaning Systems for Vertical Panel Fish Screens
Vertical plate fish screens have been installed at a number of locations within the Pacific Northwest The vertical orientation of the screen panels requires screen cleaning systems designed...
A Method to Study Suspended Sediment Induced Flow Characteristics Changes
Sediment-laden turbulent flows occur in nature and through man-made hydraulic structures. Our current understanding of this two-phase flow phenomenon is incomplete, and many important...
Soil Water Chemistry of Irrigation with Drainwater
The use of drainwater for irrigation was demonstrated as a management option that reduces net farm drainage and provides control over water quality (O'Brien and Guitjens,...
Hydraulic Effects of Habitat Structures in Flood Control Channels
Three field sites have been established and laboratory flume experiments begun to assess the effect of habitat enhancement measures on water-surface profiles and local scour in flood control...
Design of the Inlet/Outlet Tower for the Eastside Reservoir Project
The Eastside Reservoir is currently being constructed near Hemet, California, by the Metropolitan Water District of Southern California. When completed in 1999, water will enter and be...
Evaluation of System Downstream Control
System downstream control (SDC) has been developed to optimally and automaticaly control canal systems. The objective of system downstream control is to maintain a reference water depth...
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...
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...
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...
A System Approach for Identifying and Improving Hydraulic Numerical Modeling Reliability
A system response approach which uses Fourier transform through a multiple-input/ single-output (MISO) nonlinear system to evaluate the model performance of verification and simulation...
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...
