Land Application of Dredged Material at Port Manatee
Maintenance dredging of approximately 600,000 cu yd of highly plastic clay was conducted in October 1983. This material was deposited on a nearly 200 acre tract of farmland in a depth...
Dredging Developments in the Canadian Arctic
The use of dredges in the Canadian Arctic in connection with oil exploration programmes has lead to the adaptation of existing and adoption of new techniques. Further development is required...
Agricultural Crop Production and Quality Effects when Soils are Amended with Dredged Lake Sediments
Lake renewal achieved by pumping loose sediment from the lake bottom requires a disposal area for that sediment and the associated water. Application of this sediment to agricultural land,...
Placing of Impermeable Underwater Membranes
An impermeable underwater membrane has been applied successfully in the construction of a lowered road section in the Netherlands. In this paper the construction technique is discussed...
An Offshore Mound Constructed of Dredged Material
The concept of using dredged material to intentionally construct an underwater mound was tested and confirmed at the Dam Neck Disposal Site, 4 miles offshore Virginia Beach, Virginia....
Acoustic Silt Density Measurement
Significant savings can be achieved on the costs of operations for the deepening and maintenance of navigation channels and harbor basins in muddy areas provided that computations are...
Case History: North Slope Alaska Hydraulic Dredging
Alaska's North Slope Borough, with the aid of dredging machinery consultant Michael Weston, and geotechnical consultant Rittenhouse-Zeman & Associates, has pioneered...
Safe Landfilling of Contaminated Dredging Spoil
This paper deals with the assessment of the expected emissions of toxic substances from highly contaminated harbor dredged material. The material in question arises from the canal between...
Aquatic Bioassays in Dredged Material Management
Dredged material ranges from gravel and coarse sand to fine silts and clays, and may be free of contaminants or highly contaminated with a variety of chemicals from industrial, municipal,...
Development of the Dredging Wheel
The 'bucket line' dredge and 'cutter suction' dredge are two distinct types of equipment. The cutter suction system has developed more...
Soil Analysis and Dredging
Analysis of soils before dredging can make or break a dredging project. It is seldom possible to obtain all of the information needed for selecting equipment and estimate outputs. The...
Capped In-Water Disposal of Contaminated Dredged Material
The Seattle District and the Corps of Engineers Waterways Experiment Station (WES), Vicksburg, Mississippi, are cooperating in a field demonstration study to evaluate the effectiveness...
An Application of Acoustic Core Analysis
This technique has shown itself to be extremely successful at Roberts Bank, in a highly variable bottom material, where shallow depths were not a significant problem, and some borehole...
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...
Plunge Pool Erosion in Cohesive Soils at Two Dams in Kansas
Results of a field study of two plunge pools scoured by horizontal pipe outlets discharging on cohesive channels are analyzed. Formulas for critical tractive shear stress based on plasticity...
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...
Sedimentation Study for the Rochester, Minnesota, Flood-Control Project
In a cooperative effort, the U. S. Army Engineer District, St. Paul (NCS), and the Soil Conservation Service (SCS) planned a combined flood-control project. The SCS portion of the project...
Coping with High and Low Pressures of Transient Flow
Conditions exist in most long distance water pipelines, such that abnormal but inevitable occurrences will cause transient flow. Often the most crucial conditions for consideration by...
