A hydraulic model study is being conducted at the Alden Research Laboratory, Inc. (ARL), to study the effects of adding a hydroelectric generating station at the site of an existing lock...
Loose Riprap Grade Control Structure Design
The Soil Conservation Service has been using loose riprap grade control structures based on the equal energy concept for several years with mixed success. Previous model studies resulted...
Improved Intake Design for Downstream Migrating Fish at Hydropower Plants
Fish guidance efficiency of screens is a function of the submergence of a hydropower intake. The submergence of an intake can be reduced through the use of intake extensions or guides...
Gropps Lake Dam
Gropps Lake Dam has a concrete ogee spillway with earthen abutments at either end of the spillway. The dam features an internal drainage system, outlet works, an energy dissipator, a steel...
G.I.S. Applications in Nonpoint Source Pollution Assessment
A Geographic Information System (GIS) provides a flexible tool for developing the oftentimes cumbersome soils and land use mapping database required in watershed storm water management...
A Knowledge-Based System for the Environmental Design of Waterways (ENDOW)
Knowledge-based software systems accept problem descriptions from users and apply logic in order to generate a solution or solution set. These systems function over very narrow problem...
LISP or CLIPS: Selecting an Expert System Tool in Hydraulic Engineering
The transfer of Artificial Intelligence(AI) technology from the research laboratories to the scientific and engineering environments has been made possible by phenomenal advances in computer...
GIS Visualization Techniques in Surface Water Resource Planning
Geographic information system (GIS) computer graphic displays of surface water resource conditions provides a means for valuation-by-visualization (VBV) of alternate plans. GIS display...
Verification of WASURO Using the Puerto Nuevo Physical Model Study Results
The Jacksonville District, US Army Corps of Engineers, used the hydraulic design computer modeling program, WASURO, for preliminary design of the Rio Puerto Nuevo Flood Control System....
Combined Application of HEC-1 and HEC-2 Simulation Models in Dike Safety Analysis
The potential flood impact of a breach in a dike for a large spreading-area on a nearby waste storage facility was investigated. An HEC-1 model was used for generating breach hydrographs...
Detention Basin Design to Control Flood Volumes
A desk-top method is presented for hydraulic design of detention basins. The main objective is to control the flood volume rather than the peak discharge. The method is based on the pre-determined...
Rainfall-Runoff Modeling in a Small Urban Watershed
Knights Branch watershed is located in Dallas, Texas, and it covers an area of about 5 mi2 (13 km2). Due to...
Liability Insurance Coverages for Designers of Temporary Structures
A recent survey completed by the American Consulting Engineers Counsel (ACEC) indicates that in 1990 approximately 40 claims occurred per 100 firms. There also is an indication that claims...
Limit States Design of Wooden Formwork for Concrete Walls
Load and resistance factors are developed for ultimate limit states design of wooden formwork components for concrete walls when the lateral concrete pressures are computed using the ACI...
FHWA'S Bridge Temporary Works Research Program
The Federal Highway Administration (FHWA) has developed a research program to address bridge falsework design and construction. This resulted from the collapse of the Route 198 bridge...
Development of Standards for Slipform & Jumpform Works
Review of past work indicates substantial effort has been made to publish construction standards and guidelines for slipforms but published material pertaining to jumpforms is scarce....
Temporary Lateral Support System for Historic Building Facades in Boston
This paper describes a system of vertically cantilevered structural steel trusses, designed by the author, that provided temporary lateral support for a group of five and six story, 120...
Who Pays for the Unexpected in Construction: Hi-Rise Engineers Point of View
The unexpected in high-rise construction can be traced to design criteria evolving from environmental models and probes, as well as 3 general problems dealing with quality control in contract...
A Design for Automated Pavement Crack Sealing
An automated crack sealing system can have substantial economic benefits including reduced labor costs, improved quality, and improved safety. While automating crack sealing is technically...
Animation of Automated Space Construction
