Gas Transfer and Secondary Currents in Open Channels
Laboratory flume experiments on water-wide controlled gas transfer, such as reaeration, are described. The experiments indicate that gas transfer is a surface renewal process, well described...
The Effect of Storms on Pollution Loading Estimates
A rather extensive field and modeling program is underway in the Sandusky Bay/Nearshore region of Lake Erie and the objective of this paper is to summarize the preliminary results of a...
Storm Dynamics in the Lake Ontario Region
A program package, RAINPAK, was written to develop appropriate rainfall input, based on concepts of the physical processes behind the temporal and spatial distribution of storm rainfall...
Effect of the Fluid Velocity on the Biofilm Development
In order to get basic information concerning the application of a biological treatment to the ammonia nitrogen removal from drinking water, we considered the relation between the biofilm...
Grand Canyon Water Line by Directional Drilling
The South Rim Village at Grand Canyon National Park obtains its water supply from a point called Roaring Springs which is located approximately 15 miles across the Canyon on the North...
In-Situ Microocosms for Calibrating Dynamic Models
The calibration of dynamic water quality models for lakes and reservoirs requires significant quantities of data, experience, and judgement. In particular, the identification of an appropriate...
Analysis of Freshwater Distribution System at the Long Beach Naval Complex
This account of the evaluation of freshwater pipelines at California's Long Beach Naval Complex discusses current methods for assessing the condition of damaged water lines....
Advancements in Aerodynamics, Fluid Mechanics and Hydraulics
The theme of these Proceedings is Advancements in Aerodynamics, Fluid Mechanics, and Hydraulics. As indicated by the title, the subject crosses disciplinary boundaries and deals with flow...
Rapid Assessment of Seismic Vulnerability
The choice of a seismic damage assessment method depends fundamentally on how the assessment will be used, but always involves definition of the expected ground motion and the structure...
ATC Methodology and Data for Rapid Assessment of Seismic Vulnerability
Recently developed Applied Technology Council (ATC) methodology and data provide a technical basis for rapid assessment of structure seismic vulnerability. Methodology developed under...
Nonlinear Quasi-Static and Transient Response Analysis of Shallow Shells: Formulations and Interior/Boundary Element Algorithms
Nonlinear integral equations are derived for the representation of displacements of shallow shells undergoing moderately large, quasi-static or dynamic deformations. A combined interior/boundary...
Seismic Response of Pipes Supported on Complex Frames
Analytical approaches and modeling techniques used to calculate seismic responses of piping systems, supported on complex open-frame structures, are evaluated. Seismic responses are obtained...
Offshore Platforms Subjected to Wave Forces
The dynamic analyses of offshore platforms are mostly based on the lumped mass matrix method in the frequency domain. Although the approximations involved in the lumped mass matrix method...
