Discharge Characteristics of Overshot Gates
Overshot gates are becoming increasingly popular for controlling water levels in open channels because of the ability of the gates to handle flow surges with limited depth changes. While...
The Effects of Water Surface Profiles on Manning's Roughness Coefficient
The Manning Equation has wide application in engineering practice. Nonetheless, certain aspects of it are still not widely understood. Often, engineers deduce the value of Manning's...
Contraction Scour at Bridges: Analytic Model for Coarse-Bed Channels
Contraction scour at bridges spanning coarse-bed channels is evaluated based on mass conservation of both water and transported sediment between a reference channel section near the crossing...
Mitigation Measures for Eroding Muddy Shores
A criterion for the stability of muddy coasts is proposed, accounting for bottom resistance, hydrodynarnic forcing and sediment supply. Although qualitative, this criterion provides a...
A Three Dimensional Oil Spill Model
This paper reports the development and testing of a comprehensive three-dimensional oil spill model. At present time, the model components include advection and turbulent diffusion, vertical...
Capillary Pressure-Saturation Relationships in Fracture
Understanding and quantifying unsaturated flow through fractures in rocky slope is important for design and construction of drainage system in large-scale hydraulic engineering. The data...
Comparison of Near-Field Dilutions Derived from In Situ Measurements and Simulated Dilutions at the Sand Island Sewage Outfall Plume, HI
Near-field dilutions of the Sand Island Treatment Plant (SITP) wastewater plume were derived from salinity measurements made at the sewage outfall between Sept. 25?Oct. 1, 1994, a period...
Irrigation of Grain Sorghum on the Delmarva Peninsula
Irrigated grain sorghum experiments were conducted for two years on a Norfolk sandy loam soil. Full irrigation was compared to partial irrigation and no irrigation in a randomized block...
Scour Protection in Bottomless Culverts
This paper will describe the relative severity of scour anticipated to occur at bottomless culverts and will provide some design guidance for scour protection based on research referenced...
Designing Concrete Culverts to Resist Scour Damage
Concrete culverts have been used for over 100 years. In this period, the main design concern centered on structural and hydraulic adequacy of the culvert. Scour is a relatively recent...
Regional Economic Impacts of a Land Fallowing Program?The Palo Verde Test Land Fallowing Program Case Study
The Metropolitan Water District of Southern California (MWD) and the Palo Verde Irrigation District (PVID) implemented a two-year test land fallowing program (Program) from August 1, 1992...
Laboratory Evaluation of a Conductivity Probe for Scour Monitoring
Laboratory tests were used to evaluate the ability of conductivity sensors to measure streambed elevation. Tests were completed on a 2.1-m probe with a resolution of about 8 cm that was...
Evaluation of Selected Instruments for Monitoring Scour at Bridges in New York
Reliable methods to monitor scour at bridges are needed to ensure public safety and minimize the cost to repair or replace vulnerable bridges. The U.S. Geological Survey, in cooperation...
Sedimentation Dynamics of Tidal Inlets
Tidal inlets are very dynamic systems subject to continuous morphological changes under the action of tides, waves and transported sediments. Although flow and sediment dynamics are interactive,...
Adhesion Kinetics of Fuel Oil #6 and Oil-in-Water Emulsions on Marine Sediments under Turbulent Mixing Conditions
Oil spilled in the marine environment is subject to a great variety of physical, chemical and biological processes, which determine its ultimate fate in the aquatic environment. Many of...
Tensioned Fabric Structures
A Practical Introduction
The objective of this publication is to provide basic information about the nature and characteristics of tensioned fabric structures. Its target audience includes architects, engineers,...
Creeping Suspicion
High-capacity, epoxy-coated anchors were installed at Upper Occoquan Dam to increase the stability of the 70-foot-high concrete gravity dam and powerhouse under revised Probable Maximum...
Building an International Community of Structural Engineers
This proceedings, composed of two volumes, contains the papers presented at the American Society of Civil Engineers (ASCE) Fourteenth Structures Congress held in Chicago, Illinois, USA,...
