Modeling Vertical Stratification in the Pamlico River Estuary Using Modern Hydrodynamics
A modern hydrodynamic model is applied to the Pamlico River estuary. Good agreement was obtained between measured and predicted water elevations and salinity distributions during the one...
A Flexible Curtain Structure for Control of Vertical Reservoir Mixing Generated by Plunging Inflows
To maintain salmon habitat in the Sacramento River, efforts are being made to pass cold water inflows through Whiskeytown Reservoir, California, with minimal warming. In Whiskeytown, summer...
Sacramento River Environmental Requirements
Environmental requirements have altered bank protection engineering and construction on the Sacramento River, California. Conflicts between public safety and environmental protection remain...
Flow Diversion in a Steep, Coarse-Bed Stream
A case study is presented of the hydraulic design of a diversion structure in a high velocity, coarse bed streamcourse. Mill Creek, a tributary to the Upper Jordan River in the southern...
The Definition of a Short Composite Column
A `short' column in composite construction is defined as one which can be designed for its cross-section strength alone without the need to consider stability effects. An extensive study...
Depth of Cover Surveys for Waterway Crossings
The majority of pipelines cross at least one waterway of some type, especially the interstate lines which from start to end cross numerous bayous, canals and major rivers. These waterways...
Pipelines Crossing Highways and Railroads by Tunneling
When new pipeline construction requires the crossing of highways and railroads, a pipeline is generally installed in pipe or tunnel linear plate encasement which has been installed by...
Earthquake Risk GIS Analysis for Ningxia Hui Autonomous Region, China
The Ningxia Hui Autonomous Region is a small autonomous region in the eastern part of northwest China and below Inner Mongolia with an area of 66,400 square meters. Ningxia's population...
Geographic Information System Planning for Geotechnical and Earthquake Engineering Applications at the Savannah River Site, SC
The Savannah River Technology Center (SRTC) of the Savannah River Site is in the planning stages of compiling a geological, geophysical, and seismological data base on an industry standard...
Closing the Gap: Transit Revenue Opportunities
The LandEagle Project is based on the premise that public transit systems can be financially self sustaining; an idea usually greeted with wonder and amazement. This paper explores methods...
Pin Piles Save Silos
The United Grain Corp. annually ships about 200 million bushels of wheat and other grains to destinations around the world from its leased facility on the Columbia River at Vancouver,...
Drilling with Direction
Norfolk, Va.'s 48 in. diameter raw water main crosses three rivers in its 52,000 ft route. At the Elizabeth River, an aerial or subaqueous crossing was not feasible, so a...
Bi-Directional Load Testing of Shafts to 6000 Tons
This paper describes the use of Osterberg cells (O-cells) to perform bi-directional load testing on full size production drilled shafts for a major bridge foundation near Owensboro, Kentucky....
Lessons Learned from Elk Creek Dam
This is the third of a series of papers published on the design and construction of Elk Creek Dam. The first paper discussed design and construction concepts to provide water tightness...
Concepcion Dam Design & Construction Problems and Their Solutions
Concepcion Dam is a curved axis gravity structure 68 m high and 695 m long. It supplies water to Tegucigalpa, the capital of Honduras. The dam contains 290,000 cubic meters of RCC. Challenges...
Construction of Urugua-I RCC Dam
Considerations concerning the RCC construction process and its relation with the design and quality are analyzed. The paper contains topics related to the experience obtained at Urugua-i...
57 Years of Coastal Engineering Practice at a Problem Inlet: Indian River Inlet, Delaware
This paper presents a review of Indian River Inlet's behavior in its natural state prior to jetty construction and summarizes the level of understanding of coastal processes and inlet-bay...
An Engineering Assessment of Hydrodynamics and Beach Response at Little River Inlet, NC-SC
The Waterways Experiment Station's (WES) Coastal Engineering Research Center (CERC) conducted an analysis for the U.S. Army Engineer District, Charleston (SAC) of the monitoring data collected...
The Flow in the Front Stagnation Region of a Square Plate with a Small Disturbing Wire in its Upstream
The flow in the front stagnation region of a square plate was investigated experimentally in a water channel. A small wire was placed in the upstream of the square plate to create a small...
Pressure Losses Across Sequential Stenoses in Collapsible Tubing
The fluid dynamics of a model of a diseased artery with multiple stenoses were investigated in a recirculating steady-flow system over a range of Reynolds numbers (Re) from 30 to 1100....
