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...
An Interagency Overview of Selected Stream Sedimentation Models
The author's experience in developing stream sedimentation models is presented. The interagency study consisted of three phases. Phase one involved making an inventory of the computer...
Assessing Stormwater Impacts
The evaluation of stormwater effects to watershed ecosystems must adopt an integrated approach due to the inherent complexity of assessing such environments, arising from the vulnerability...
Why Design Storm Methods Have Become Unethical
This paper discriminates between continuous and event modelling, and describes some dimensions of ethical design for sustainable ecosystems. Arguments are presented that event modelling...
Modeling Hydrologic and Pollutant Transport Processes for Stromwater Runoff to Surface Waters
Combined sewer overflows and stormwater discharges, which are considered point sources, and certain nonpoint sources (NPSs) display the characteristics of precipitation-driven events....
Coping with EPA's Transportation Storm Water Permit
EPA has released NPDES storm water monitoring data from group applicants. This paper will analyze the data to determine which pollutants are present in storm water runoff from transportation...
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...
Combined Stormwater Drainage and Treatment
Due to continuing public concern regarding environmental protection for the nation's waterways, new and more stringent water quality control regulations have been developed. This is most...
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,...
Numerical Experiments on Instability in Unsteady Flow Modeling
The problem of numerical instability in modeling unsteady open-channel flows is investigated using the technique of numerical experiments. The model is based on the one-dimensional de...
Fortification of MMOC Models for Steep-Channel Flows
The Multimode Method of Characteristics(MMOC), designed to solve unsteady flows, is a new comprehensive scheme formulated by merging several individual characteristic schemes of the specified-time-interval...
Numerical Modelling and Laboratory Verification for the Turbulent Flow Field in the Branching Channel
Adopting the depth-averaged k-? turbulence model and using the finite volume method and SIMPLE procedure, the turbulent flow field in the branching channel is numerically solved and verified...
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...

Partnering for Success
Partnering as a method of doing business is spreading throughout the construction industry. With everyone fed up with the litigious nature of the industry, partnering represents an opportunity...
Investments in the Future
The projects that earned the 1994 Outstanding Civil Engineering Achievement Awards of Merit were improvements to the nations transportation and environmental infrastructures. On the outskirts...
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...
Reclaiming Water With Wetlands
Drought is a fact of life in southern California. The limited supply of potable water could stall economic growth in the region and may be available only in restricted amounts for environmental...
