Numerical Modeling for Sediment-Pass-Through Operations of Reservoirs
Numerical modeling using the FLUVIAL-12 model was made to determine the feasibility and effectiveness for Sediment-Pass-Through (SPT) operation for Cresta and Rock Creek Reservoirs in...
Reservoir Sediment Removal: Hydrosuction Dredging
Hydrosuction dredging is a relatively little-known method of removing sediment deposits from reservoirs. The method is similar to traditional hydraulic dredging except the difference between...
Bed Material and Numerical Modeling in a Gravel/Cobble Bed Stream
The characteristics of bed material in a cobble or gravel river and their use for numerical simulation of flushing flow needs are discussed. There are three types of bed material: 1) material...
Use of HEC-2 and HEC-6 to Determine Levee Heights and Revetment Toe Scour Depths
The paper presents the use of HEC-2 and HEC-6 to determine levee heights and revetment toe scour depths. These adjustments are due to the U.S. Army Corps of Engineers, Los Angeles District...
Hocking River Sedimentation Study
The channel improvement project located on the Hocking River in Athens, Ohio is estimated to have prevented over 68 million dollars in flood damages since its completion in 1971. However,...
Management of Sediments on the Red River Waterway Project
The Red River is a large alluvial river system with the lower 280 miles currently being developed for shallow draft navigation. The navigation project entails construction of five locks...
Sedimentation and Remediation Aspects of Recreation Lakes
Relatively higher rates of silting in Lake Shafer, Indiana during the past few years have been a matter of concern to its owners, operators, and users. Potential causes for observed increases...
Sediment Modeling in the Rio Grande Conveyance Channel
The Rio Grande Conveyance Channel and the Rio Grande Floodway convey water from the San Acacia diversion dam to Elephant Butte Reservoir. The Conveyance Channel was built in early 1950's...
Performance of Submerged Vanes for Control of Sediment in an Irrigation Canal
Removal of accumulated sediments from irrigation canals is necessary in order to maintain canal capacity. Removal of these sediments may be enhanced by directing and concentrating sediments...
NPDES Storm Water Permit Compliance at Air Force Installations
Recent changes to the National Pollutant Discharge Elimination System (NPDES) program require that storm water discharges associated with industrial activity be regulated under the NPDES...
Costs and Benefits of Meeting the San Francisco Bay Copper Objective by Regulating Small Treatment Plants
Metals in aquatic environments, even in very small amounts, are of concern because of potential toxicity to aquatic life forms. Copper is of particular concern in the San Francisco Bay...
Non-Point Pollution Loadings and their Impacts on Tennessee Valley Reservoirs
This is a three-year study which began in March 1992. The project has focused on inflow streams entering storage projects including Douglas, Cherokee, South Holston, Watauga, Norris, Chatuge,...
Non-Point Source Pollution Reduction
The paper reports on the results of a study to determine the effectiveness of the best management practices (BMPs) for use in the Tampa Bay Watershed. The study aims to determine the efficiency,...
Thermo-Hydrodynamic Modelling of the Chicago Sanitary and Ship Canal
A one-dimensional numerical model of the Chicago Sanitary and Ship Canal and Lower Des Plaines River has been developed as a tool for assessment of the waterway's thermal response to actual...
Development of Long-Term Three-Dimensional Hydrodynamics in Long Island Sound for Use in Water Quality Modeling
The Blumberg-Mellor (1987) three-dimensional hydrodynamic model has been adapted by the National Oceanic and Atmospheric Administration's National Ocean Service (NOS) to provide hydrodynamic...
Design and Testing of Two Ice-Preserving Winter Lake Aeration Systems
As part of an effort to achieve ice-preserving lake aeration for winterkill prevention, two non-mixing lake aeration systems were designed and field tested. Each creates a fish refuge...

Chicago's Waterfalls
The 1994 Outstanding Civil Engineering Achievement Award goes to successful implementation of an elegantly simple idea: aerate sluggish water by letting it fall through man-made waterfalls....
Deicing Denver
Glycol-based deicing fluids are an essential part of winter operations at most airports. While these chemicals help ensure safe and timely aircraft operations, stormwater runoff contaminated...
