Structural Control of Ground-Water Induced Debris Flows
A number of case studies have attributed debris flow initiation to the effect of elevated pore pressure from a bedrock ground-water source. Debris flows on slopes underlain by Precambrian...

This paper gives a brief description of Lake Bosten, its importance to Xinjiang Province of the PRC, objectives of an on-going study, and some preliminary results. This on-going study...

Task Committee on Transport Processes at the Interface of Water Column and Bottom Sediment
The Task Committee on Transport Processes at the Interface of Water Column and Bottom Sediment was formed on October 1, 1989 under the Technical Committee on Hydrologic Transport and Dispersion...

A Review of the State-of-the-Art in Sediment-Water Column Interaction Measurement Techniques
This paper reviews the state-of-the-art measurement techniques available to water quality modeling practioners to estimate: (a) sediment oxygen demand rates, (b) sediment-water column...

Water Supply and Aeration Demands for Shrimp Farms
A computer model was developed simulating flow and aeration requirements for a range of farm sizes, from 50 to 2000 hectares. Climatic effects and water quality upset conditions were included...

Shop Creek Stormwater Quality Enhancement Project
The advent of NPDES regulations for stormwater discharges creates a need to verify, on a regional basis, the effectiveness of emerging water-quality control technologies such as extended...

CORMIX2: Expert System for Multiport Diffuser Discharges
The Cornell Mixing Zone Expert System (CORMIX) is a series of software systems for the analysis, prediction, and design of aqueous toxic or conventional pollutant discharges into watercourses,...

Evaluation of the ARS Low Drop Grade Control Structure
The ARS low drop grade control structure was developed by Little and Murphy to provide efficient energy dissipation and effective grade control for streams in northern Mississippi. The...

An Expert Advisor for Selective Withdrawal Operations
A rule-based computational advisor that aids in the selection of selective withdrawal operations for project release temperature maintenance is discussed. This advisor couples a one-dimensional...

Physical Forces Generated by Barge-Tow Traffic Within a Navigable Waterway
Movement of navigation traffic such as barge tows within a restricted inland waterway such as the Illinois, Mississippi, or Ohio Rivers can and will alter the flow field in and around...

Effects of Low Drop Grade Control Structure on Bed and Bank Stability
The channel response upstream of a low drop grade control structure was documented using field investigations, analysis of the engineering properties of bank materials, and repeat cross...

Hydraulic Modeling of Flow Control Gates
Flow control gates are subject to complex hydrodymanic loadings, which may in many cases only be predicted through investigation on a physical hydraulic model. Scaling of gate models,...

Storm Water Management and Wetland Restoration?Ballona Channel Wetlands
A storm water management plan was engineered to provide storm water dention necessary for site develop and at the same time to allow wetland restoration. Objectives of the project were:...

River Engineering and Environmental Resources
The federal government and the Corps of Engineers (CE) are committed to preserving and enhancing environmental quality. Research and development support for this commitment in the realm...

Measurement of Hydraulic and Environmental Effects of Aeration Devices in Douglas Reservoir
The releases from Douglas Reservoir experience periods of low dissolved oxygen (DO) content during the summer months. Tests were conducted during August 1989 to determine the effects of...

Sacramento's Proactive Stormwater Permit Program
In January 1990, with the encouragement and assistance of the California Regional Water Quality Control Board-Central Valley Region (Regional Board), the City and County of Sacramento,...

Long-Term Numerical Simulation of Three-Dimensional Hydrodynamics of Chesapeake Bay
A time-varying 3D numerical model of Chesapeake Bay has been developed to provide flow fields to a 3D water quality model of the bay. The water surface, 3D velocity field, salinity, and...

Urban Stormwater Quality Enhancement
Source Control, Retrofitting, and Combined Sewer Technology
This proceedings contains the papers presented at the Engineering Foundation Conference on Urban Stormwater Quality Enhancement - Source Control, Retrofitting and Combined Sewer Technology,...

The Stacked Drift Tunnel
The Mount Baker Ridge Tunnel is the first of its kind and the last: a forward thrust of technology and a look back to the flow of federal highway funds, which paid 90% of its cost. The...

An Update on the U.S. DOE Ocean Energy Program
This paper summarizes recent research accomplishments of the program and provides a synopsis of planned activities leading to a Net Power-Producing Experiment (NPPE), to be conducted at...
