Comparing Flood Stage-Discharge Data?Be Careful!
A long term stage-discharge record is extremely valuable data. However, simplified applications of long term records to draw sweeping conclusions about man's effects should be avoided,...

Simulating Flow in the Tidal Potomac River
A one-dimensional unsteady flow model has been applied to the tidal Potomac River, including its major tributaries and marginal embayments, between Washington, D. C. and Indian Head, Md....

Real-Time Monitoring for Ohio Basin Water Management
The Ohio River Division (ORD) of the Corps of Engineers operates 77 reservoirs in this basin for the purposes of flood control, conservation, hydropower, low flow augmentation, water supply,...

Real-Time Monitoring and Flood Forecasting in Harris County, Texas
A new automated flood warning system is now serving the 2,700,000 residents of Houston, Harris County, Texas. Real-time rainfall and river level data from more than 90 sensors are automatically...

Real-Time Flood Forecasting on Small Computers
A real-time, rainfall-runoff, flood forecast model, developed by the Corps of Engineers Hydrologic Engineering Center (HEC), was applied to two of tributary basins in the Ohio River System....

Application of Geographic Information System for Hydrologic Investigation
The Illinois Department of Energy and Natural Resources is developing a geographic information system (GIS) under the federally funded Lands Unsuitable for Mining Program (LUMP). This...

State Space Approach to Flood Stage Estimation
A flood routing and stage prediction model is developed using the techniques of State Space and Kalman filtering. The governing equation is the physically based hydrologic method of flood...

Computer-Based Predictions of Atchafalaya Bay Sedimentation
The Atchafalaya River, a distributary of the Mississippi River, discharges into Atchafalaya Bay through the Lower Atchafalaya River and Wax Lake Outlet. The bay delta has grown rapidly...

The Impact of the I-664 Bridge-Tunnel Crossing on Sedimentation
A sedimentation evaluation was made of the proposed I-664 Bridge-Tunnel complex across the James River, Virginia. This paper briefly describes the procedures used and the results obtained...

Open Channel Flowrate Measurement Using Multipath Acoustic Flowmeters
Recent acoustic flowmeter developments have improved the applicability and accuracy of the multipath acoustic measurement technique. Accuracy, hardware cost and calibration cost can be...

Levees at St. Louis?More Harm Than Good?
The U. S. Army Corps of Engineers, St. Louis District (SLD), conducted an evaluation into the effects of Federal flood control projects on St. Charles County. Questions to be addressed...

Computer-Based Design of River Bank Protection
A study using the FLUVIAL-11 computer model was made for the Rillito River in order to determine the design configuration for the bank protection which must contain the design flood and...

Eight Open Channel Flow Programs for the Apple IIe Microcomputer
The purpose of this paper is to present eight programs in hydraulics and hydrology suitable for running on the Apple IIe and Apple IIc microcomputers. The programs are: Flood 1, Flood...

Water Surface Profiles in Compound Channels
The paper explores the use of the proposed compound channel Froude number in problems of water surface profile computation. It can be used not only to determine critical depth and to identify...

Boundary Shear Stress in a Meandering Channel
Longitudinal and transverse velocity, bed shear, and water surface elevation were studied in a fixed-bed, meandering, laboratory channel with naturally varying, non-prismatic cross sectional...

Numerical Modelling of Bed Evolution in Braided Channel Systems
The overall modelling approach adopted is based on an assumption of quasi-steady flow. The numerical algorithm is based on a split-operator approach, in which the flow energy equation,...

Biological Evaluation of Angled Screen Test Facility
The paper presents comparisons of model and prototype measurements as a means for evaluating the ability of a physical model to reproduce a geometrically complex prototype thermal intake...

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...

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....

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;...
