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...

Analysis of Model Uncertainty Using Bayesian Monte Carlo
Bayesian Monte Carlo analysis combines Bayesian inference with standard Monte Carlo techniques to provide improved estimates of the uncertainty in water quality model parameters and results....

Longterm Response of Lakes to Acidic Deposition
The longterm response of lakes in the northeastern United States to different levels of acidic deposition was predicted by using a lumped parameter hydrologic/biogeochemical model, the...

Nonpoint Source Loads and Phosphorus Budget for Lake LBJ
Nonpoint source loadings from stormwater runoff are a major contributor of pollutant loadings in many locations. A phosphorus budget is developed for Lake Lyndon B. Johnson (LBJ). Lake...

Southeastern Drought of 1988?A Federal Perspective
The drought that has plagued the Southeastern United States for most of the 1980's is continuing in two major river basins within the geographic boundaries of the South Atlantic...

A Multivariate Analysis of Stillwater Lakes, Nevada
Stillwater Lakes located in western Nevada has been experiencing an astounding number of fish and waterfowl deaths since August 1986. This problem is explored through a multivariate statistical...

Decision Support for Short Term Export Sales From a Hydroelectric System
A stochastic dynamic programming (SDP) model was recently developed and implemented at British Columbia Hydro and Power Authority (B.C. Hydro) to provide decision support for short term...

Storms and the Occurrence of a Turbidity Interface/Maxima in a Fresh Water Estuary
A combination of Landsat, field data and modeling analyses reveals a turbidity interface/maxima in the lower reaches of a freshwater tributary or 'estuary.' Mode...

Settling Basin Model for the Personal Computer
The SETSIZE program, models sediment deposition in a settling basin. The program can be applied to determine the length of time until dredging or cleaning is necessary or solve for an...

Incremental Damage Assessment (IDA) For Lake Darling Dam
An Incremental Damage Assessment (IDA) has been completed for Lake Darling Dam, located on the Souris River, near Minot, North Dakota [1]. The IDA has indicated that a reduction in flood...
