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...

REMOTS Sediment Profiling at the Field Verification Program
Disposal of uncapped highly polluted Black Rock Harbor muds took place in April-May 1983 at a buoy located within the Central Long Island Sound Disposal Area in 62-66 feet of water. Baseline...

Strip Mine Reclamation Using Dredged Material
This alternative was investigated through the creation of a field study to demonstrate the feasibility of using a cover of dewatered dredged material to reclaim surface mine deposits....

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...

Improved Techniques for Removal of Sediments Contaminated with Hazardous Materials
Realizing the need to improve the capabilities of response personnel in dealing with cleanup operations involving contaminated sediments, the U. S. Coast Guard and the U. S. Environmental...

Sediment Resuspension from Dredging Activities
Dredges are a logical choice for removing contaminated sediments from our Nation's waterways. Historically, the dredging industry has emphasized increased production in an...

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 Testing of a Large Make-Up Pipeline
A 37 mile pipeline which consists of sections of 114 inch, 96 inch and 66 inch pipes was constructed for delivering secondary sewage effluents for power plant makeup. During initial operations,...

Flow and Scour Patterns around Gabion Structures
There is a need for simple, inexpensive and effective means for streambank protection and fish habitat enhancement. Initial results are presented of laboratory research on the performance...

Local Scour at Fish Rocks
There is a growing interest in the enhancement of rearing habitat for juvenile anadromous fish in the Pacific Northwest. This has focused attention on the need for a better understanding...

Prototype Studies of Corps of Engineers Structures Experiencing Cavitation Damage
A number of Corps of Engineers structures have sustained damage caused by the occurrence of cavitation. The damage has varied from slight pitting to severe erosion. The damage has occurred...

Sedimentation Consolidation Models?Predictions and Validation
In very soft sediments, questions have arisen concerning the capability of standard computational techniques used to implement calculations. The problems mainly lie in the manner in which...

From Field to Map�Untouched by Human Hands
After a few years of experience with computerized surveying systems, surveyors are finding that increased efficiency and accuracy are justifying capital expenditures. Several users of...

A Home for the Navy's Trident Subs
On 7,000 acres near Seattle, Washington, sits the largest military base constructed in the U.S. since World War II. The Navy's multimillion-dollar Trident project, a combination...

Alaska's Native Log Bridges
There are several thousand bridges of this type which carry heavy logging trucks in Alaska and remote areas of the lower 48 states. Covers bridge safety, wheel-load distribution, field...

Surveying Takes Another Giant Step Forward
The introduction of short-range electronic distance measurement in 1971 revolutionized surveying. Thousands of surveying and engineering firms across the U.S. today routinely use EDM for...

Best Ways to Dewater Dredged Material
Left to its own devices, fine-grained dredged material placed in confined disposal areas reaches an equilibrium water content near its Atterberg liquid limit. The high water content of...

Threaded Rebars Spin Down Time
A rebar splicing technique was a major factor in saving two year's construction time on California's $33 million, 9000 ft (2743 m) Antioch Bridge. Rebar splicing...

Current Trends in Design and Construction of Embankment Dams
This report is concerned primarily with the embankment itself although foundation and abutment treatment are considered essential elements of the embankment. It covers a broad range of...

Intermediate Service Levels in Water Distribution
This paper is concerned with design standards for secondary water distribution networks. Based on field studies in the Middle East and Africa, mathematical equations were developed for...
