Infiltration Trenches for Urban Runoff Control
A two-dimensional finite element model has been developed to simulate the transient flow in a variably saturated porous medium for the study of infiltration trenches. Parameters such as...
UNET: A Model of Unsteady Flow Through a Full Network of Open Channels
UNET is a PC-based dynamic wave, unsteady flow model for the solution of the full network problem. The program applies a linearized implicit finite difference scheme to solve the full...
Glacial Basin Flow for a Power Operation Model
A power operation model was developed and used to estimate the project energy generation and reservoir level fluctuations. In order to precisely simulate the daily project operation, daily...
Utilization of Expert Systems for the Operation of Reservoir Systems
This paper illustrates how knowledge-based expert systems can obtain, organize, document, store, and utilize valuable complex reservoir systems experience, obtained by experienced water...
Channel Changes in the Platte River, 1926?1986
The Platte has changed significantly during the last century. A meandering channel with extensive riparian vegetation growth has replaced, the once braided and unvegetated channel in some...
Flushing Flow Analysis Concepts
Many environmentally oriented groups who oppose water resources projects, have conceived various types of flow requirements to supposedly meet a variety of biological purposes in rivers....
Idealized Debris Flow in Flume with Bed Driven by a Conveyor Belt
The generalized viscoplastic fluid (GVF) model is used to derive the theoretical expressions of two-dimensional velocities and surface profile for debris flow established in a flume with...
Fixed-Wheel Gates Uses and Limitations
The fixed-wheel type of gate, which derives its name from sets of wheels mounted on axles fixed to the gate, rolls upon and transmits the hydraulic load of the gate to guide tracks bearing...
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...
Economic Trade-Off between Hydropower and Other Competing Water Uses: A Case of Coteau Creek Station
Using the Coteau Creek hydropower generating station in Saskatchewan as a case study, economic trade-offs between water used for hydropower generation, and irrigation and recreational...
Simulations of Multireservoir System Operation
Simulation modeling has evolved from a direct examination of operating policies into operational decision support systems, integrated multiple use expansion planning systems and special...
Efficiency and Vibration Testing
To gather the necessary data to assure the most efficient and reliable operation of the system, Idaho Power Company implemented a plant testing program in 1988. The testing program consists...
Flow Characteristics in an Irregular Spillway Model
A physical model of the spillway for a proposed water supply reservoir near Meridian, Texas, was constructed to determine the optimum spillway design which would maintain an acceptable...
Freeboard Allowances for Chute Spillways
Allowances must be made for the physical phenomena which cannot be modelled, such as wave action, air bulking, splash and spray; the simplifications of behaviour implicit in the calculations;...
Physical Model Study of New York State Dam
The New York State Dam is located on the Mohawk River near its confluence with the Hudson River. Downstream from the dam, the river flow is divided into six channels as the water passes...
A Design Parameter Study of Turbine Draft Tube by Viscous Flow Analysis
Viscous flow analysis based on the full Reynolds-averaged Navier-Stokes equations is being applied to predict successfully turbulent flow characteristics and energy losses in different...
Mitigation of Ice Effects at Hydroelectric Intake Structures
The design and operation of hydroelectric facilities throughout the northeast United States and Canada must contend with winter conditions for a large part of their yearly operation. During...
Tailwater Management for Beneficial Uses
Tailwaters can provide significant benefits for recreation, fisheries, assimilative capacity for treated wastewaters, and water supply for municipalities and industries. Development and...
Using IFIM at the Upper Greenwich Project and Other Hydropower Developments
The Instream Flow Incremental Methodology (IFIM) is widely used at numerous hydroelectric projects today for determining flow releases. IFIM is capable of quantifying changes in aquatic...
Computerized Measurement of Turbine Flow and Performance, Including Penstock Protection
The application of computer technology now makes it possible to measure turbine flows accurately, reliably and economically. The measurement is based on the differential pressure produced...
