Hydrodynamic Dispersion: Estimation and Prediction
The dispersion of dissolved, nonreactive tracers in groundwater is governed by diffusion and advection. A.E. Scheidegger introduced the term dispersivity to describe the effect that a...
A Numerical Solution Technique for Incompressible Flow
Presented is a numerical solution technique which employs the explicit predictor-corrector scheme of R.W. MacCormack in solving the governing two-dimensional equations of motion on a staggered...
Computer Aided Hydraulic Design of Open Channels

Debris-Flow Research and Engineering Practice
For debris-flow analysis to enter standard engineering practice, future research must extend existing models to deal with major complications that arise in field practice. This paper reviews...
Two-Dimensional River Modeling of Buckhorn Creek
A two-dimensional Finite Element Surface Water Modeling System (FESWMS-2DH) was used to simulate flow at a bridge crossing of a heavily vegetated flood plain where State Highway 130 crosses...
The Liquid Droplet Radiator in Space: A Parametric Approach
This study is a parametric investigation of the performance and operating characteristics of a cylindrical Liquid Droplet Radiator (LDR) for use in space. The LDR system mass per heat...
Surgery in the Microgravity Environment
As man becomes more active in space, the possibility of major medical emergencies requiring surgical procedures will increase. Surgery in the microgravity environment involves many challenges...
Simulated Water-Quality Changes in Detention Basins
A study has begun to simulate movement of stormflow through detention basins at four locations in the Irondequoit Creek watershed and determine the effect on peak flow and water quality....
Preparations for the Future?The European Highway Community
The need for infrastructural capacity in the future in Europe has been investigated by the European Conference of Ministers of Transport - ECMT. The principal traffic considered was international...
Natural Vibrations of Cables in a Flowing Fluid
Cable segments are important components in a wide variety of marine operations. Their nonlinearities are primarily geometric as characterized by large displacements and load-dependent...
Analysis of Hydraulic Impacts at the Tucson Reclaimed Water Recharge Project
The Tucson Reclaimed Water Recharge site has been implemented with increasingly sophisticated calculation methods as data collection efforts advanced. Initial project scoping utilized...
Jet Fuel from the Ground Up
The Port Authority of New York and New Jersey has implemented a multi-million dollar clean up effort to remove oil lenses beneath the bulk fuel farms it maintains at three New York area...
Design Considerations for a Navigational Channel
The hydraulic feasibility of the proposed navigation channel from Shuwaikh to the offshore area in Sulaibikhat Bay was studied. Channel width and alignment were determined considering...
Freshwater Inflow Requirements of a Texas Estuary
The objective of this study is to estimate the amount and scheduling of freshwater inflows required to maintain fishery productivity, especially shrimp, in Matagorda Bay, Texas. To estimate...
Waste Disposal in Coastal Waters
The increasing concentration of population and industry on coastal areas, is making greater demands for coastal disposal. However, the coastal waters are also used for recreation, and...
Quantification of Net Shore-Drift Rates in Puget Sound and the Strait of Juan de Fuca
The objective in this study was to determine the annual rate of net shore-drift at selected sites within Puget Sound and the Strait of Juan de Fuca. These sites were selected based on...
Numerical Solutions for Problems Related to Nearshore Morphology?!
In the development of numerical models of nearshore morphology various steps can be envisaged: 1. initial models: the initial bottom topography remains unchanged; spatial variations in...
Tractive Flows Adjacent to Site for Submarine Sewage Pipeline
Twin 3200 m long submarine sewage pipelines for the city of Vancouver are being placed across the outer tidal flats and upper slope of the Fraser River delta to a water depth of 107 m....
Coriolis and Our Land-Sea Environments
The characterizations of the Coriolis Acceleration Vector with water pile-up and circulating currents, which produce shoreline erosion or accretion were presented at the Coastal Zone 85...
Practical Application of Acoustic Doppler Profilers
This paper discusses the advantages and limitations of the acoustic Doppler current profiler (ADCP), and it reviews some of the experience gained to date with the ADCP relevant to currents...
