Convection-Diffusion Analysis of Sedimentation in Initially Dilute Solids-Suspensions
The settling of suspended solids in solids-suspensions is treated from the viewpoint of the relative fluxes established as a result of the upward diffusion of water and the downward convection...
Infrastructure: Money and Methods
State and local governments have started to cope with their infrastructure problems by passing bond issues, establishing infrastructure banks to centralize resources and decision making,...
Dispersal of Wastewater in the Ocean--A Cascade of Processes at Increasing Scales
An engineering system for marine waste disposal is described. Design decisions are based on broad categories of input information: the complete description of the waste to be discharged;...
Japanese Experience with Intake Designs
To diversify its power sources, Japan has operating or under construction some 37 nuclear power units. This technology and the design criteria are imported from the U. S. The power plants...
Experimental Study of Stratified Cooling Ponds
Experiments in a laboratory physical model were conducted to analyze the hydrothermal performance of vertically stratified cooling ponds. Temperature, velocity, and fluorescent dye measurements...
Utilizing a Wetland System for Urban Stormwater Management
The many benefits of utilizing wetland systems as an integral part of an urban stormwater management plan include flood protection (detention), water quality enhancement, and upgrading...
Incorporating a Hydro Plant into a Municipal Water System
While recently reformulating water use strategy and policy in association with the development of a new water supply reservoir, a large North Carolina municipality was prompted to assess...
