Instream and Streambank Environmental Feature Guidelines
Tightened regulatory requirements and a renewed appreciation for the benefits of preserving our diminishing natural resources have led to a recent profusion of stream restoration projects...
A Fish Bypass Screen at Puntledge Project
An Eicher screen has been designed for the Puntledge Diversion Project on Vancouver Island in British Columbia, Canada. Its purpose is to reduce the mortality of downstream migrating juvenile...
Fish Entrainment and Strategies for Diversion
Hydroelectric power projects often impound reservoirs which contain important recreational fisheries. The entrainment of fish through these facilities and the possible associated entrainment...
An Improved Design of Fishways Under High Variation of Headwater
For the purpose of mitigating environmental impact, it is necessary to build fish passing facilities for fish migration when a dam is constructed on a river. But when the headwater variation...
Sandstone Materials Used as Riprap
A study was conducted to determine if sandstone materials could be potentially used as riprap. Nineteen rock samples (16 sandstone samples) were collected in six western states. The rock...
West Columbus, OH LPP Gate Closure Analysis - A Study of the Requirements for Multiple Closures
Providing flood protection by levees and/or floodwalls often requires the use of temporary closures, in lieu of the more expensive relocation of highways and railroads, in order to maintain...
Climatic Perspective on the 1993 Mississippi R. Flood
The 1993 summer flooding in the Upper Mississippi River Basin was the most devastating flood of modern times with damage estimates in the range of 15-20 billion dollars. The paper describes...
Impacts of the 1993 Flood on the Mississippi River in Illinois
The 1993 flood has now been recognized as one of the greatest floods on the Mississippi and Missouri Rivers. Its geographical extent included portions of Iowa, Missouri, Illinois, Wisconsin,...
Evaluating an Autoregressive Model for Stream Flow Forecasting
Daily stream discharge generated by an Autoregressive Model is helpful in the design and risk assessment of temporary riverine construction projects. This case study uses actual daily...
Problems of Stream Flood Simulation and Prediction
The article presents a report on the natural flooding in a stream and the problems encountered when simulating and predicting stream floods. The complexity of flood characteristics, the...
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...
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,...
