Contaminant Fate and Transport Model in Pool-and-Riffle Streams
The complex nature of solute transport and transformation processes in natural streams has been investigated using numerical solution of a proposed mathematical model. This model is based...
Lake Michigan Diversion at Chicago
Water has been diverted from Lake Michigan to the Mississippi River basin beginning with the construction of the Illinois and Michigan Canal in 1848 to serve navigation needs. During the...
The Regulation of Lake Ontario During the Spring of 1993; a Period of Record Supplies
A wet summer in 1992 and record water supplies to Lake Ontario during early 1993 resulted in very high levels on the lake. Actions by the International St. Lawrence River Board of Control...
Multi-Reservoir Systems Optimization by the Aggregation/Decomposition Methodology
Studies on long term optimization of multi-reservoir systems are enhanced by the availability of closed-loop policies as available in Stochastic Dynamic Programming (SDP). SDP offers a...
Pipe Utility Evaluations With the Aid of GIS
Geographical Information Systems (GIS) are starting to be used on a day to day basis to solve community problems and optimize the use of their valuable resources. One engineering application...
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...
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...
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...
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...
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,...
Floodflow Effects on Riparian Vegetation in Arizona
A relation for estimating changes in the condition of riparian vegetation as a function of stream power was developed for stream channels in central Arizona. Flood and vegetation data...
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...
Air Concentration Measurements in Highly-Turbulent Flow on a Steeply-Sloping Chute
The U.S. Bureau of Reclamation's (Reclamation) stepped spillway overtopping protection research program required air concentration profile data be obtained during testing in a large, 15.2-m-high...
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...
Modeling Kinetics of Sediment Removal in Water Columns
Many physical, chemical, and environmental factors govern the rate of cohesive particle sedimentation in aquatic environments. A new information-based model that uses experimental information...
Flow and Chloride Transport in the Tidal Hudson River, NY
A one-dimensional dynamic-flow model and a one-dimensional solute-transport model were used to evaluate the effects of hypothetical public-supply water withdrawals on saltwater intrusion...
