Water Supply
The Foothills Project adds 125 mgd (5.5 m�/s) to the Denver area water treatment capacity, and saved approximately $1 million in energy costs in the first year of its operation. The $163...
Refuse Recycling
The refuse recycling plant at Columbus, Ohio, is a pioneer in burning as fuel a combination of refuse and coal. This hybrid fuel has advantages over burning either alone. One winter in...
Caisson
The Jamaica Bay Water Pollution Plant was renovated and upgraded from l973-l983 and included sinking a 116 ft. x 105 ft. caisson 50 ft. deep adjacent to city streets and buildings. The...
Sewage Plant
The Sacramento Regional Wastewater Management Program cost $460 million, took 10 years to build, and solved problems in sludge disposal, odor control, conveyance systems, combined sewer...
A Case Study in Low-Level Radioactive Waste Storage
Capital funds have been appropriated for the design, engineering, and construction of an interim low-level radioactive waste storage facility. This project is currently in the preliminary...
Onsite Storage Facility for Low Level Radwaste
The Tennessee Valley Authority (TVA) has designed and constructed an onsite storage facility for low level radwaste (LLRW) at its Browns Ferry Nuclear Plant in northern Alabama. The paper...
Safety Investigations of Existing Spent Fuel Storage Structures for Increased Spent Fuel Storage Capacity
Delays in the solution of disposal problems continue to create the need for additional on-site spent fuel storage capacity at commercial nuclear power generating facilities. Rod consolidation...
Allen-McColloch Pipeline Computer Based Control System
The Allen McColloch Pipeline (AMP) was designed to deliver 416 cfs of treated water from the Metropolitan Water District of Southern California's Diemer Water Treatment Plant...
Environmental Engineering
The purpose of the Annual Conference on Environmental Engineering is to pursue scientific knowledge and promote sound engineering judgement and practice in the solution of the many environmental...
The Theory of One-Dimensional Consolidation of Saturated Clays
The theory of nonlinear finite strain consolidation is reviewed. A modification of the effective stress equation to account of settling and consolidation as a unified phenomenon is proposed....
Particle Interaction and Stability of Suspended Solids
The physics of particle interaction, which is responsible for the problem of the apparent tardy settling of suspended solids in tailings discharge slurries containing initially low concentrations...
Validation of Consolidation Properties of Phosphatic Clay at Very High Void Ratios
The void ratio-effective stress and void ratio permeability relationships for phosphate slime mine tailings were measured by several methods. The measurements were used in nonlinear finite...
Consolidation of Mining Wastes
This paper describes laboratory and field tests for determining consolidation properties of soft sediments, presents data on several types of mining wastes, and presents the results of...
Prediction of Viable Tailings Disposal Methods
A sand-fines-water diagram is proposed to analyze and describe slurries composed of coarse and fine particulate matter. The diagram can be used to predict and plan disposal methods for...
Waste Phosphatic Clay Disposal in Mine Cutsr
Research was undertaken to assess the applicability of waste clay disposal back into phosphate mine cuts. The pit was monitored for two years with measurements of clay surface elevation,...
Centrifugal Modeling of Phosphatic Clay Consolidation
As a by-product of beneficiation, quantities of dilute clay slurry are produced which are stored in retention ponds. One method of accelerating consolidation is to surcharge the clay with...
Application of Finite Strain Consolidation Theory for Engineering Design and Environmental Planning of Mine Tailings Impoundments
A knowledge of the consolidation behavior of mine tailings, during and after deposition, is important in estimating final impoundment capacity, rate and pore fluid expulsion during and...
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,...
Thalweg Disposal: Demonstration of an Alternative
Disposal of dredged material in the main channel, or thalweg, is an alternative disposal option for maintenance dredging. The material dredged from the Upper Mississippi River is clean...
