Perspectives on Modelling Consolidation of Dredged Materials
The physical and mathematical aspects of this problem are highly nonlinear and material-property relationships extend beyond the scope of standard geotechnical engineering. The potential...
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...
Trends in Computerization in the Eighties
This paper addresses trends in computer-aided productivity tools for Civil Engineers in the eighties. Certain aspects of the past history, present status, and future of CAD/CAM and CAE...
Water for Resource Development
The primary goal of these proceedings is to provide an awareness of the many areas of resource development in which hydraulic engineering plays a key role. The papers cover a variety of...
Modeling the Drying of Dredged Material
The drying of dredged material was modeled mathematically as a diffusive process and the governing equation was solved using an integral method. Closed form solution equations are presented...
Impacts of an Overboard Disposal Operation
The objective of this study was to establish an acceptable dredge disposal site which would be physically and environmentally suitable for periodic use over the 50-year project life of...
Dredged Material Disposal Modeling - Chesapeake Bay
A plan to deepen the approach channels to Baltimore Harbor from 42 feet to 50 feet involves in part the overboard disposal of about 9. 5 million cubic yards of dredged material in the...
Turbidity Generated by a Model Cutterhead Dredge
The study of turbidity generation indicates that, in general, turbidity increases with an increase in the cutter speed and an increase in the cutter swing velocity. A silt curtain deployed...
Computer Models for Dredged Material Disposal Planning
Short term and long term planning for the disposal of dredged material can be significantly enhanced using state-of-the-art computer modeling. Computerized mathematical models can be constructed...
Shoaling Problems and Improvements Sunny Point, North Carolina
The Military Ocean Terminal, Sunny Point (MOTSU), is located on the Cape Fear River, approximately 18 miles downriver from Wilmington, North Carolina. The facility has experienced significant...
The National Dredging Data Management System
The ADDAMS computer program is a collection of user-friendly computer models for planning, designing and managing confined disposal areas. Models which can be used to determine the size...
Dredge Cutterhead Flow Processes
Feasibility studies of new dredge intake and cutterhead shielding techniques were conducted to improve hydraulic cutterhead dredge performance. Simple modification of the suction mouth...
Mixed Layer Modelling of Stratification in Lakes
Mathematical models for vertical heat transfer processes in lakes and reservoirs are grouped into two classes: diffusion models and mixed layer models. In recent years much of the progress...
Modeling of Estuarial Hydrodynamics and Water Quality
The estuary is perhaps the most complex environmental system with which the analyst must deal. Driven largely by tides and hydrologic fluxes, its hydromechanical behavior is further modified...
Numerical Model of Mississippi River at Lock and Dam 26
Replacement work was initiated in November 1979. The first stage cofferdam constricted about half of the river channel. As a result, the flow velocity at the constriction increased causing...
Development of Response Plans for Toxic Spills
A plan is proposed for managing the response to a toxic spill into a river system and the minimization of its effects on water utilities, industry and the environment. As technical aids...
Hydraulic Uncertainty in Risk Analysis
Considerable effort has been expended in defining and evaluating hydrologic uncertainties; however, the analysis and evaluation of hydraulic uncertainties has received little attention....
Dynamic Reliability Models for Hydraulic Structures
In addition to the determination of capacity and layout of hydraulic structures under normal design, one other important but related task that faces engineers is the evaluation of reliability....
Reliability Analysis as Reflected from the Fourth International Symposium on Stochastic Hydraulics
Reliability analysis is perhaps one of the most practically important branches of the general field of stochastic hydraulics. Its potential applications include quantitative evaluation...
