Horizontal Density-Gradient Effects on Simulation of Flow and Transport in the Potomac Estuary
A two-dimensional, depth-integrated, hydrodynamic/transport model of the Potomac Estuary between Indian Head and Morgantown, Md., has been extended to include treatment of baroclinic forcing...
Slurry Removal From a 2-D Fluidized Region
A two-dimensional fluidization experiment is performed on fine sand with a 5.08 cm diameter source pipe with horizontally opposed orifices, 0.317 cm in diameter, spaced 5.08 cm. Slurry...
A Study on Estimation of Aquifer Parameters in Unsteady Seepage Flow
A method which automatically identifies aquifer parameters is proposed in this paper. The aim of this investigations is to estimate transmissivities and storage coefficients of unsteady...
3-D Cavity Flow Analysis by a New Fractional Step Method Based on the Finite Element Method
This paper describes a new finite element scheme for solving the time-dependent incompressible viscous fluid flow expressed in terms of the Navier-Stokes equations. The main feature of...
Long-Term Numerical Simulation of Three-Dimensional Hydrodynamics of Chesapeake Bay
A time-varying 3D numerical model of Chesapeake Bay has been developed to provide flow fields to a 3D water quality model of the bay. The water surface, 3D velocity field, salinity, and...
An Acoustic Doppler Discharge-Measurement System
A discharge-measurement system that uses a vessel-mounted acoustic Doppler current profiler has been developed and tested by the U.S. Geological Survey. Discharge measurements using the...
Effects of Turbulence on Price AA Meter Rotors
Field and laboratory studies were conducted during 1988 and 1989 by the U.S. Geological survey to determine the effect of turbulence on the performance of price AA meter rotors. Two different...
Limitation to Standard Parshall Flume Calibrations
Parshall flumes are widely used for metering open channel flows. An inspection of the original study which developed the rating equations indicates that the flumes were not tested for...
Urban Stormwater Quality Enhancement
Source Control, Retrofitting, and Combined Sewer Technology
This proceedings contains the papers presented at the Engineering Foundation Conference on Urban Stormwater Quality Enhancement - Source Control, Retrofitting and Combined Sewer Technology,...
The Stacked Drift Tunnel
The Mount Baker Ridge Tunnel is the first of its kind and the last: a forward thrust of technology and a look back to the flow of federal highway funds, which paid 90% of its cost. The...
Selection of Hole Size for Fluidization Pipes
Two-dimensional fluidization experiments are performed on fine and medium coarse quartz sands at depths of 25.4 and 42 cm. Four supply pipes are used with orifice diameters of 1.587 mm...
A Semi-Empirical Model for an OC-OTEC Spout Flash Evaporator
A phenomenological model for the thermal-hydraulics of a spout flash evaporator is presented in this paper. The model considers the two-phase flow behavior both in the spout and in the...
Asphalt in the U.S. Transportation Infrastructure
Asphalt has been the major pavement material responsible for development of the transportation infrastructure enjoyed by American citizens. This paper addresses issues to be monitored...
Resin Transfer Process Modelling: Computational & Experimental
In most cases, the resin transfer molding (RTM) researcher has a fundamental understanding of composites and possibly some mold design experience. The areas of resin flow dynamics and...
Use of Voluntary Consensus Standards by the Bureau of Reclamation
This paper outlines how the Bureau of Reclamation has historically participated in standards development for emerging technologies, and how present standards are applied or adapted for...
Construction Quality Assurance for Geomembranes
The results of and lessons learned from construction quality assurance (CQA) programs on 19 geomembrane liners are presented. The specifications are generally exceeded by comfortable margins...
Concrete Pavement?Specification by Modeling
Concrete pavement specifications have traditionally been prescriptive with construction in-put defined. This practice does not include a definition of the product intended, restricts innovation,...
Significance of Yield Surface Corner-Like Effects in Inelastic Stability Solutions
This paper presents the author's experiences with finite element prediction of the inelastic stability of steel plate structures. The implications of linear versus nonlinear...
Hydraulics/Hydrology of Arid Lands (H?AL)
This proceedings consists of papers presented at the International Symposium on the Hydraulics and Hydrology of Arid Lands which was held in conjunction with the 1990 National Conference...
Stratified Flows
This volume contains the edited and refereed proceedings of the Third International Symposium on Stratified Flows, convened on February 3-5, 1987 in Pasadena, California. It consists of...
