Computation of Gradually-Varied Flows in Channel Networks
For computing steady-state, gradually-varied flows, a new algorithm is presented which allows solution of the entire channel system simultaneously, and unlike other available methods,...

Numerical Simulation of Stratified Flows
The two-dimensional width-averaged equations for flow in estuaries or resevoirs are derived, and the basic assumptions are stated. The heat and salt conservation equations are coupled...

The Role of Hydraulics and Sediment in Large River Ecology
The National Science Foundation has sponsored a project under the long term ecological research (LTER) program which is called the 'Illinois Rivers' LTER project....

SCADA and Network Analysis
Connecticut Natural Gas Corporation (CNG) is a gas distribution utility serving 130,000 customers in Connecticut. Gas purchase costs and pipeline maintenance costs account for 65% of CNG's...

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...

Lake Water Level and Sediment Management?Case Studies in Illinois
Estimation of the sedimentation in the lake is based on the soil erosion rates in the watershed, the sediment transport in the stream system, and lake trap efficiency. Erosion rates are...

Analyses of Sediment Transport Data by Microcomputer Software
The MINITAB statistical software project has been popularly used on mainframe computers since 1972. In June 1984, a subset of the program was made available for the IBM-PC microcomputer;...

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...

Fish Diversion in Hydropower Intake
Hydraulic model studies were conducted to develop a fish screening system to be used in the turbine intakes of Priest Rapids Development on the Columbia River, Washington. The system studied...

Microcomputer Applications in Flood Management
Historically Salt Lake City has been subject to flooding from spring snow melt runoffs. Even though the volume and the rate of runoffs were similar during both years, the 1984 runoff created...

Exfiltration Trench Design as Part of a Stormwater Management Plan
The paper discusses a program structured to assist the design consultant or the agency reviewer by means of a menu driven format. A flood routing microcomputer program developed by the...

3-D Orthogonal Curvilinear Circulation Modelling
A three-dimensional circulation model has been developed using an orthogonal curvilinear coordinate system. The model as constructed is capable of simulations on a variety of time and...

Three-Dimensional Simulation of Flow, Salinity, Sediment, and Radionuclide Movements in the Hudson River Estuary
The three-dimensional, finite difference model FLESCOT was applied to a 106-km reach of the Hudson River estuary in New York between Chelsea and the mouth of the river. It predicted the...

Hydraulic Study Requirements for Bulb Type Hydropower Units at a Navigation Lock and Dam
A replacement Lock and Dam at Alton, Illinois on the Mississippi River is presently under construction. This paper presents the results of studies performed for adding six bulb type hydropower...

Unique Utilization of a Physical Model to Develop a Construction Sequence of a Major Cofferdam
Lock and Dam 26 Replacement is being constructed on the Mississippi River about 2 miles downstream of the existing Locks and Dam No. 26 at Alton, Illinois. This paper discusses the unique...

Microcomputer Program for Daily Weather Simulation
Extensive climatic data have been collected by the National Weather Service and other agencies, and are available in printed form or on magnetic tapes. The published data are expensive...

Macro Data Acquisition Systems on Minicomputers
Selection of the proper minicomputer for a real-time data system is a careful design process based on system requirements. Hardware should be purchased after requirements are set and not...

Computer Techniques for Acquisition and Reduction of Cross-Section Data
DuPage County, Illinois, has initiated a county-wide stormwater management program for planning and flood mitigation purposes. Field data with horizontal and vertical control are obtained...

Water System Analysis?Modeling Hydraulics
The work described in this paper is part of the planning and design effort for expanding and improving the water supply system for St. John the Baptist Parish, Louisiana. The parish is...

Near Real-Time Climatic Data in Illinois
The need for making real-time climatic data available for use was recognized in Illinois, and a concerted effort began in 1983 to develop a system for collecting and disseminating near...
