Genetic Algorithms in Groundwater Management
The aim of this paper is to examine applicability of genetic algorithms in groundwater planning and management. A brief description of genetic algorithms and the associated advantages...
Groundwater Development and Related Issues
Optimum development and management of ground water resources requires consideration of all elements of the groundwater system and their inter-relations with total hydrologic cycle along...
An Attempt of an Aquifer Model with Lack of Data
The University of the Americas in Cholula, Puebla, Mexico withdraws water from an unconfined aquifer. Also the city of Cholula and the city of Puebla withdraw water too. A model aquifer...
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...
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...
Unsteady Spillway Inlet Conditions at the Weatherford Water Supply Reservoir
The Weatherford Water Supply Reservoir, in Weatherford, Texas has had frequent lake-side flooding and has experienced unstable spillway operation. Residents complained that the water had...
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,...
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...
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...
