Development of Transport Model for Groundwater Planning and Management in Taipei Basin
The objective of this paper is to develop a groundwater model for contaminant transport simulation. The transport model, in conjunction with the previously developed flow model, is used...
Flood Monitoring Network In Southeastern Louisiana
A flood monitoring network has been established to alert emergency operations personnel and the public about hydrologic conditions in the Amite River Basin. The U.S. Geological Survey...
HEC River Analysis System (HEC-RAS)
The Hydrologic Engineering Center (HEC) is developing next generation software for one-dimensional river hydraulics. The HEC-RAS River Analysis System (HEC, 1994) is intended to be the...
Revised Hydraulic Design of the Rio Hondo Flood Control Channel
The US Army Engineer District, Los Angeles has completed a major review study of the Los Angeles County Drainage Area (US Army, 1992) and has determined that the existing flood control...
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...
Hydro Plant Research Data Acquisition System
The Colton Hydroelectric Development, located on the Raquette River in the northwestern part of New York State, is the site of a two year research project to test the use of heated trashracks...
Improved Hydraulic Features of the HEC River Analysis (HEC-RAS)
The Hydrologic Engineering Center (HEC) is in the process of developing a Next Generation (NexGen) of hydrologic engineering software. The goal in the area of river hydraulics is to develop...
MAC3D: Multiblock Numerical Model for Hydraulic Applications
The MAC3D computer code is a three-dimensional numerical model for incompressible flow. To enhance geometric flexibility, it uses multiblock grids, which are composite structured grids...
Depth-Averaged Flow Model in Curvilinear Coordinates
Implementation of a depth-averaged model in orthogonal curvilinear coordinates permits to resolve questions about grid refinement, the representation of complicated boundaries, and the...
A Three-Dimensional Numerical Simulation of Seasonal Flow and Salt Transport in the C&D Canal
Two seasonal-scale, three-dimensional hydrodynamic models with salt transport using CH3D-WES were constructed to represent the most critical periods of environmental concern: fishery spawning...
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,...
Some Benefits of Grid by Number Sampling
Describing the overall sediment composition of gravel-bed river reaches and depositional bars is a difficult problem due to spatial variations in the sediment size. Past research has focused...
Laplace Valve Stroking for Complex Piping Systems
LaPlace valve stroking to control water hammer is applied in complex piping systems with friction and without friction. Two types of system are analyzed. The law of operation of the valves...
Expansion and Contraction of Powder River Between Moorhead and Broadus, MT: Geomorphic Observations and Numerical Modeling
Sixteen years of annual surveys demonstrate that the channel of Powder River expands at high flows and contracts at low flows. Channel contraction is associated with the formation of benches...
