A New Look at Old Man River
After the 1993 Midwest flood, a research team conducted one of the largest aerial mapping projects in U.S. history�a year-long, $3.7 million effort that demonstrates the utility of photogrammetry...
Sustainable Development, Botswana Style
A sustainable development project in Botswana, Africa, collected information on industrial wastes. Sustainable development is defined as development that meets the needs of the present...

Florida's Big Bellies
FPL designed and installed double reverse tapered poles, affectionately called big belly because the width gradually increases toward the middle and narrows at both ends. The poles replace...
Grouting to Great Depths
Logan Martin dam on the Coosa River in Alabama has been plagued by underseepage since its construction in 1964. The karst forming the dam's foundation allows water to flow...
Calendar: Bridges 1998 Calendar
Featured bridges are: C&O R.R./Lafayette Street Underpass Bridge (VA); Clear Creek Bridge (UT); Stoneman Bridge (CA); Marble Fort Bridge (CA); Rocky Mountain Viaduct (VA); Smokemont...
Returning Veteran
The Veteran's Memorial Bridge on the Cuyahoga River is a vital link in the transportation system of Cleveland and a gateway to the city's downtown area. But time...
Historical Development of Bridge Scour Evaluations
Scour of bridge foundations (piers and abutments) is the largest single cause of bridge failures in the United States. Conversely, uncertainties of the scour depth at bridge piers and...
Siting Low Profile Grade Control Structures for the Muddy Creek Demonstration Stream Restoration Research Project
In the Fall of 1993 Reclamation began a demonstration stream restoration research project on Muddy Creek, near Great Falls, Montana. Muddy Creek captures return irrigation flow from a...
Features of a Chevron Weir Rock Ramp
This paper presents the features of a new type of low profile grade control structure, the chevron weir rock ramp. As the name infers, the planform of the structure is in the shape of...
Distributed Parameter Hydrologic Modeling and NEXRAD for River Forecasting: Scale Issues Facing the National Weather Service
With the advent of NEXRAD (Next Generation RADar), the National Weather Service has the opportunity to move from current lumped parameter modeling to more of a distributed parameter hydrologic...
Three-Dimensional Numerical Model for Fish Bypass Studies
This paper describes a numerical model developed for evaluating different options for fish bypass systems at Wanapum Dam on the Columbia River, WA. The model predicts the complex patterns...
An Extended Relaxation Technique for Unsteady Flows in Networks
A recent enhancement to the FLD WAY model is the addition of an extended relaxation technique for modeling unsteady flows in a dendritic (tree-type) network of channels with tributaries...
Application of High-Resolution Schemes to Free Surface Flows in Irregular Channels
A 1-D flow model employing a high resolution scheme based on the Total Variation Diminishing concept is applied to non-prismatic channels of irregular cross-section. The hydraulic properties...
Depth-Averaged Equations for Free Surface Flows
Depth-Averaged equations for free surface flow are derived by applying fundamental physical principles of mass conservation, momentum and moment of momentum on a control volume from the...
Effect of Grade Control Structures on DEC Streams
Controlling the grade of a channel with structures has been an effective means applied to streams. Although, the effectiveness of grade control structures is not readily apparent until...
Siting of Grade Control Structures
In siting a grade control structure in a stream, hydraulic considerations must be integrated with other important siting factors. A review of several of the important siting factors is...
White River Fish Screen Project?Hydraulic Modeling
In 1983, Puget Sound Power and Light Company (Puget Power) proposed in a license application to FERC for the overall White River Project replacement of the existing fish screens constructed...
Hydraulic Performance of Open Channel Breaching
Flood flow in natural channels with floodplains is often confined in the main channel by the presence of levees. The hydraulic performance of these kinds of channels can be seriously affected...
