Construction Through Crude Oil
When the Hilltop Interceptor project in Cleveland confronted oil-saturated sandstone, designers had to rethink their shaft construction and support procedures. Among the hazards were volatile...
Financing the Future of Storm Water
For Sarasota County, Fla., draining storm water no longer means draining municipal funds. By establishing a modern storm-water utility, the county has provided a dedicated funding source...
Hydraulics of Subsurface Flow Constructed Wetlands
Resistance to flow through subsurface flow wetlands is described by Darcy's law or by Ergun's equation. Both representations are combined with the continuity...
Application of a Hydrodynamic Model in Design of the Kingman Lake Wetland Restoration Project
The U.S Army Corps of Engineers Baltimore District is restoring 45 acres of wetlands within Kingman Lake in the District of Columbia through the placement of dredged material from the...
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...
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...
Hydraulic and Engineering Considerations in Designing Constructed Treatment Wetlands for a Lake Restoration
A 12,600 ha (31,000 acre) hypereutrophic lake in central Florida is being restored by constructing a 2,020 ha (5,000 acre) wetland filter to remove suspended sediments and particulate...
Water Control Structure Choice for Wetland Restoration/Creation
Ducks Unlimited is a non-profit conservation organization, whose mission is to fulfil the annual life cycle needs of North American waterfowl by protecting, enhancing, restoring, and managing,...
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...
Engineering Features of the Red Bluff Research Pumping Plant
In 1995, the construction of the Red Bluff Research Pumping Plant (RBRPP) was completed. The pumping plant is a research facility for evaluating the biological/engineering features of...
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...
Analysis of Bank Stabilization in Steep Complex Streams Using A Two-Dimensional Model
In cases where the channel is fairly uniform, and not divided, one-dimensional hydraulic models, such as HEC-2, generally give adequate results for scour evaluations and bank protection...
Genetic Algorithm Design of Piped Irrigation Systems
The design of piped irrigation systems is a complex matter. In its simplest form it involves the selection of the sizes of pipes and other hydraulic elements so as to ensure that the varying...
Effects of Approach Flow Conditions on Pump Sump Design
An important obstacle to the development of a generalized sump design is the variability of flow conditions in approach areas. The geometry and alignment of the areas immediately upstream...
The Scour at Bridges Management Program in Rhode Island
The Rhode Island Department of Transportation (RIDOT) has developed and implemented a comprehensive two-phase scour susceptibility program for screening and assessment of scour at bridges....
