Utilization of the Ottawa River Regulation Modeling System (MORRO)
The MORRO model was developed in Canada for use by the Ottawa River Regulation Planning Board (ORRPB) to integrate the operation of the Ottawa River during the spring freshet season, when...
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...
Effects on Reservoir Water Quality Caused by Changes in Inflow Plume Hydrodynamics
In this paper, the effects of environmental changes on the hydrodynamic behavior of the Las Vegas Wash inflow into Lake Mead are discussed from the view-point of water quality. It is hypothesized...
Validation and Intercomparison of Three-Dimensional Numerical Models of Estuarine and Lake Hydrodynamics
Three-dimensional numerical models have been developed and used to study the circulation and transport of water quality parameters in estuaries and lakes. This paper discusses two important...
Climate Change Effects on Great Lakes Levels
The Great Lakes Environmental Research Laboratory has developed conceptual models for simulating moisture storages in and runoff from the 121 watersheds draining into the Laurentian Great...
Borden Field Data and Multivariate Geostatistics
A large-scale field experiment on natural gradient transport of solutes in groundwater was conducted in an unconfined sand aquifer in Borden, Ontario by extensive monitoring after the...
Development of a GIS for the U.S. Great Lakes Shoreline
The Computer Mapping Center of the Detroit District, U.S. Army Corps of Engineers (USACE) is developing a Geographic Information System (GIS) to contain physiographic, demographic, and...
IJC Challenges in an Era of Uncertainty
Since its creation pursuant to the 1909 Boundary Waters Treaty between the United States and Canada, the International Joint Commission (IJC) has evolved into an effective mechanism for...
How Many Years to Fill with Sediment, a Sediment Study of Lake Powell on the Colorado River
A study to determine the current capacity and to update information on the life expectancy of Lake Powell was conducted by the Bureau of Reclamation. The study documented the present storage-elevation...
Hydraulic Features of Canyon Lake Hydropower Plant
The original hydraulic features of the Canyon Lake dam were well adapted to the addition of hydropower. Design, construction and anticipated operational details of the added hydropower...
