Evolution of a Three-Dimensional Curvilinear-Grid Hydrodynamic Model for Estuaries, Lakes and Coastal Waters: CH3D
Traditional finite-difference models of estuarine, coastal and lake hydrodynamics and transport use rectangular Cartesian grids in the horizontal directions. In order to accurately represent...
A Field and Modeling Study of Fine Sediment Transport in Shallow Waters
As part of a major effort to understand and quantify the phosphorus dynamics in Lake Okeechobee, the transport of fine sediments has been studied by combining numerical modeling with an...
A 3D-Stereo Graphics Interface for Operational Great Lakes Forecasts
A system for real-time predictions of Great Lakes physics and transport characteristics is now being implemented. The full 3D nature of the predictions demands accurate, high speed computer...
Contaminant Loading from Fox River to Lower Green Bay
The heavily industrialized lower reach of the Fox River, downstream of the DePere Dam, and lower Green Bay, Lake Michigan, are modeled. Hydrodynamics and contaminant transports to the...
Effects of Forest Cover on a Snowpack in the Sierra Nevada
Adjacent snowpacks in a clearing and under a forest canopy were compared over a decade at a site near Lake Tahoe. This comparison provides a few indications of the differences in snowpack...
Validation of Hydrophysical Components of a One-Dimensional Lake Model
A dynamic one-dimensional lake model has been developed in alternative structures, MINLAKE and FRMPND, for water-quality control strategies and lake eutrophication studies. Hydrophysical...
Artificial Recharge in the Southern Ogallala?Experiences with Playa Lake Water and Filter Underdrains
Ground water in southern portions of the Ogallala Aquifer has declined significantly over the past several years. Attempts to recharge playa water in the past have failed due to the clogging...
Multi-Date Image Analyses Used for Determining Flood Area Impacts in the Saginaw River Basin, Michigan
During the months of September and October 1986, a series of storms swept across the Lower Peninsula of Michigan. These heavy downpours caused $400 million worth of flood damages. Significant...
Numerical Simulation of Mudflows from the Hypothetical Failure of a Debris Blockage Lake Below Mount St. Helens, WA
This paper evaluates the characteristics of mudflow events resulting from the hypothetical breaching of a debris blockage dam using a variety of lake levels and impounded water volumes...
Water Quality Study in an Arid Region Lake: Lake Bosten, Northwest China
This paper gives a brief description of Lake Bosten, its importance to Xinjiang Province of the PRC, objectives of an on-going study, and some preliminary results. This on-going study...
Physical Modeling Study of the Niagara River Plume
A rotating laboratory facility is used to study the dynamics of the Niagara River discharge into Lake Ontario. The current tests are limits to buoyant discharge conditions, which occur...
Validation and Recent Enhancement of a Three-Dimensional Curvilinear-Grid Finite-Difference Model for Estuarine, Coastal and Lake Circulation: CH3D
This paper describes the validation and recent enchancement of a three-dimensional curvilinear-grid hydrodynamic model: CH3D. The model employs finite-differences techniques and allows...
Overview of Mathematical Models?River Nile/High Aswan Dam
This paper has been directed towards the presentation of seven reliable planning tools (mathematical models) that can be used for the investigation of the planning options facing policy...
Decoverly Lake?Functional Hydraulics & Aesthetics
The Decoverly Office Park is located in Rockville, MD. In 1984, engineering design on the seven office building park and pond was begun by the consulting engineers. From the beginning,...
Spillway Gates for the El Naranjero Dam in Spain
In June 1986 Zwag Zschokke Wartmann Ltd received the order from Hidroelectrica Espanola S.A. in Madrid, Spain for the design and model testing of 5 radial gates on the 'El...
Modeling Not By the Numbers
A model is likely to be the tool for making predictions of the ecological impact of an engineering decision. However, ecologists often find it difficult under pressures of time and lack...
Great Lakes Waters: Too Little or Too Much?
Water supplies in the Great Lakes Basin, the world's largest fresh water supply, are more than adequate to meet current and projected needs. However, supplies could become...
A Seawall for Sea Mammals
With glass walls only 75 ft from Lake Michigan, an aquarium addition demanded solid seawall protection. Yes, in a strange twist of logic, the first step in creating a whale habitat for...
Barrier Islands: Dynamic Coastal Landforms Requiring Complex Management Decisions
Barrier islands and spits are found along ten to twenty percent of the world's coastline, and are the predominant coastal landforms composing about eighty-five percent of...
Instrumentation of Landfill Cover Liners: Moisture Transport Studies
Accurate estimation of the amount of water leaking through the cover liner, into the landfill, is vital for estimating the possible amount of leachate that can be generated into a landfill...
