Observations of Artificial Destratification
Artificial destratification using bubble plumes is one means whereby low dissolved oxygen in the hypolimnion of lakes and reservoirs may be averted. Temperature and DO were measured at...
Design and Performance of Emergency Spillway Channel Erosion Protection?Grenada Lake Dam, Grenada, Mississippi
Grenada Lake Dam located on the Yalobusha River in northeast Mississippi is part of the Mississippi River and Tributaries comprehensive plan for flood control. The 13,000-ft-long earthfill-type...
Wind Induced Circulation in Shallow Lakes
Clear Lake is a relatively shallow lake in Northern California. Natural flows are small but at times they do transport heavy metals into the lake. In order to predict water quality constituent...
What Sank the Lacey Murrow?
This month marks the third anniversary of the sinking of the Lacey V. Murrow Floating Bridge near Seattle, Wash., in the midst of a major rehabilitation project. Early on Nov. 25, 1990,...
U.S. Experience With Armor-Stone Quality and Performance
In the past 30 years problems with deterioration and cracking of armor stone in the United States have been concentrated in northern regions, particularly around the Great Lakes. The explanation...
The Assessment of Armourstone for Shoreline Protection
To protect shorelines from erosion, Ontario Hydro is using armourstone at various Generating Stations along the perimeter of the Great Lakes. Armourstone is carefully evaluated prior to...
Service Records of Chicago District Breakwater Stone and How These Relate to Test Results
Breakwater stone production is limited to areas with geologic outcrops capable of producing large rocks. The most reliable breakwater stone is that which exhibits the highest degree of...
Problems With Armor-Stone Quality on Lakes Michigan, Huron, and Erie
The instances of deterioration of armor stone at coastal structures on the Great Lakes result from numerous distinct causes, both intrinsic and extrinsic. However, the proof of specific...
Some Case Histories of Armor Stone Production
The blasting techniques used to produce armor stone, derrick stone, and underlayer stone [one to twenty tons] for the construction of rubblemound breakwalls and the confined Dike Disposal...
The 1984 Major Rehab of the Muskegon Harbor, MI South Breakwater: An Extreme Example of Misguided Design of a Stone Structure
It can be inferred from the Shore Protection Manual that the stability of any coastal structure is increased in proportion to the weights of the armorstones. The south breakwater at Muskegon...
Concrete-Faced RCC Dams
In the past 10 years, roller compacted concrete (RCC) has gained wide acceptance as a cost effective material for constructing and rehabilitating dams. Since the first RCC dams had seepage...
Rehabilitating Small Earth Embankments with RCC
The rehabilitation of existing earth dams using roller compacted concrete (RCC) is gaining wider acceptance in the engineering and construction community. Presented herein is a discussion...
Gravel Equilibrium Beach Design for Arresting Shore Erosion at Flathead Lake, Montana
Erosion of the north shore of Flathead Lake, Montana, is caused by summer wind waves generated along a 22-mile fetch. The preferred method for arresting erosion there is a beach composed...
An Overview of Segmented Offshore/Headland Breakwater Projects Constructed by the Buffalo District
Since 1977 the Buffalo District has constructed three segmented offshore breakwater projects and currently has one under construction. In addition, the District has recently completed...
Sylvan Beach Pier Rehabilitation Study
The Sylvan Beach Pier is a navigation guide jetty located at the east and of Oneida Lake in Oneida County, New York. It protects the entrance to the New York State Barge Canal which crosses...
Construction on Wisconsin's Lake Michigan Coast
This paper provides a preliminary evaluation of a set of 100 residential properties along Wisconsin's Lake Michigan coast; an examination of the vulnerability of coastal homes and adequacy...
Modeling Three-Dimensional Circulation and Sediment Transport in Lakes and Estuaries
The transport of fine sediments due to currents and wind waves in estuaries and lakes have been studied by means of field experiments, laboratory experiments, and a comprehensive three-dimensional...
Nowcast Protocol for the Great Lakes Forecasting System
The Great Lakes Forecasting System is a cooperative federal-university undertaking designed to implement a predictive system for each of the Great Lakes. The desired forecasts concentrate...
Hydrodynamic and Water Quality Modeling of Lower Green Bay
A confined disposal facility (CDF) for dredged material presently exists in lower Green Bay, Wisconsin. A planned expansion of the CDF is being studied to assess its impact on current...
Pollutant Transport Modelling in Large River Plumes
The Niagara River plume in Lake Ontario and the Fraser River plume in the Strait of Georgia are of similar spatial dimensions, and arise from rivers with comparable discharge. Both rivers...
