Hydropower
Recent Developments
The Foothills Project has been under consideration by the Denver Board of Water Commissions for many years. It is one of the major steps in the continued efforts of the Board to provide...

Numerical Modelling of Pollutant Transport from a Pond to a Stream
The problem of transport of pollutants in groundwater flow from a polluted shallow pond to a natural stream is considered. A numerical model predicting changes in quality of ground water...

Control of Select Priority Pollutants in Stormwater
A simulation program to generate the runoff quantity and quality for each storm event over a 5 year period was written. Chemical loading rate data from highways was used. Runoff was considered...

The Effects of Long Term Withdrawals on the Mid and Lower Hawthorne Aquifers, Cape Coral, Florida
The paper reports on a study to assess the water resource availability of two artesian aquifers (the mid-Hawthorn and lower Hawthorn) in Cape Coral, Florida. The impacts of future withdrawal...

Application of Interactive Computer Simulation to Water Resources Problems in Civil Engineering Education
The major educational advantage of interactive simulation is expedient demonstration of system management and control procedures and interrelationships among system variables. An 8 year...

A Ground Water Flow Model for Protection of the Northwest Well Field, Dade County, Florida
A new study was initiated to determine the appropriate cone of depression for the Northwest Well Field and to develop land use restrictions within that area. A finite-difference ground...

The Microcomputer as an Intelligent Workstation in Large Scale Hydrologic Modeling
In an effort to improve the efficiency of the hydrologic modeling activities of the Maryland State Highway Administration (MSHA), a cooperative project between MSHA, the Federal Highway...

Advances in Selective Withdrawal
The authors present the results of recent selective withdrawal research in the form of a general mathematical description of this stratified flow phenomenon. A new description for boundary...

Statewide Hydrologic Data Base and Analysis System
The Wyoming Water Research Center (WWRC) at the University of Wyoming has developed, in cooperation with the Wyoming State Engineer's Office, a statewide Water Resources Data System (WRDS)...

Flow and Mixing Calculations for a Two-Dimensional Reservoir Water Quality Model
A two-dimensional reservoir water quality box model has been developed and applied to several Tennessee Valley Authority reservoirs including a mainstem reservoir that is fully mixed vertically,...

Portland's New Water Pumping and Hydropower Station
The City of Portland, Oregon, recently placed into service a 100 mgd pumping station as a major milestone in developing a backup and emergency groundwater supply. The facility is also...

Stream Research at Coweeta Hydrologic Laboratory
Stream research at Coweeta Hydrologic Laboratory has been directed primarily towards an understanding of long-term responses to logging. Forest logging causes many changes in streams including...

Yakima Remote Control System: Supervisory Control and Data Acquisition
The Yakima Remote Control System is a computerized supervisory control and data acquisition (SCADA) system developed for the operation of the Bureau of Reclamation's Yakima Project in...

Assessment of Sediment Problems in Peoria Lake, Illinois
Peoria Lake, located on the Illinois River in Illinois, is the deepest lake in the river valley. Since 1903, the lake has experienced approximately a 31% loss of original storage capacity...

Make-up and Blowdown of a Cooling Pond
A mathematical model was developed to simulate the operation of a recirculating cooling pond for a planned nuclear power plant in the Midwest. The objective of the pond operation is to...

Quick Stroking: A Fast and Accurate Algorithm for Time-Optimal Valve Closure Synthesis
In this paper, a fast, simple, yet effective technique for valve motion synthesis is developed. This technique called Quick Stroking is applied to a practical example problem, and it may...

Cazenovia Creek Model Data Acquisition System
