Design of Riparian Habitat Replacement in Active Floodplains
Conventional flood control engineering techniques and approaches that have been traditionally been applied are now challenged by the public and no longer readily available as floodplain...

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,...

Overview of the US Army Corps of Engineers Flood Control Channels Research Program
The objective of the Flood Control Channels Research Program, currently being conducted at the US Army Engineer Waterways Experiment Station, is to develop design guidance and systematic...

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...

Bridge Hydraulic and Scour Analysis Using FESWMS-2DH
Stream crossings are usually designed to satisfy all engineering and enviromnental constraints at the lowest possible cost. As a result, roadway approach embankments leading to bridge...

Using HEC-RAS to Compute Scour at Bridges
HEC-RAS (River Analysis System) is an integrated system of software, designed for interactive use in a multi-tasking environment. The system is comprised of a graphical user interface...

Managing Border Irrigation for Near-Zero Discharge
A dimensionless database of previously executed simulations of sloping-border irrigation with tailwater runoff constitutes the heart of design-aid software showing the effects on runoff...

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...

Reduction of Downstream Impacts Through Use of Variable Detention Basin Volume Requirements
The Pre-post Match is the standard policy for regulating the design of detention basins for new developments despite evidence showing that as multiple developments occur in a watershed,...

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...

Emerging Concepts for Management of Salinity and Drainage in Irrigated Regions
The purpose of this paper is to very briefly highlight some physical and design concepts important to management of salinity and drainage in irrigated regions in an environmentally sensitive...

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...

Studies on the Erosion of a Compacted Soil
In the management of water there are certain applications in which compacted soil is used (i.e., dams, embankments, levees, spiliways, and channels). Engineers rely primarily on field...

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...

European Progress on river Renaturalisation
Most restoration projects in Europe have been designed to maximise species richness with little regard for channel stability. To recreate a sustainable natural channel it is necessary...
