Dune Profiles Before and After Storm Events in Coastal Massachusetts
It is well known that short-term changes in dune profiles can have a major effect on the severity of storm damage to coastal areas. In light of this, the standardized methodology developed...

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...

Erosion Protection at Hydraulic Structures: A Report From the Task Committee
In 1991 the ASCE Hydraulics Structures Committee formed a task committee on Erosion Protection at Hydraulic Structures. The purpose of the committee is to determine current practices in...

Flow Resistance Properties of Flexible Linings
Flow resistance for flexible channel linings is a function of the relative roughness of the lining in accordance with boundary-layer principles. As with vegetation, flexible linings have...

Cable-tied Concrete Block Erosion Protection
An articulated concrete erosion protection system is investigated as a possible revetment for bridge piers to be used in place of the traditional rip-rap revetment. The system consists...

Gully Intrusion on Reclaimed Disposal Sites
A three-phase gully erosion study was initiated at the Engineering Research Center of Colorado State University, in cooperation with the U.S. Nuclear Regulatory Commission. The objective...

Debris Flow Initiation and Termination in a Gully
A comprehensive simulation model predicting the debris-flow discharge hydrograph, solids concentration in it and the process of variation of the channel due to vertical as well as lateral...

Local Scour Measurements at Bridge Piers in Alberta
A summary of local pier scour data collected by Alberta Transportation and Utilities (AT & U) over the past 30 years is presented. Several methods used to gather this data are...

Reference Surfaces for Bridge Scour Depths
Depth of scour is measured as the vertical distance between scoured channel geometry and a measurement reference surface. A scour depth measurement can have a wide range depending on the...

Depth of Cover Surveys for Waterway Crossings
The majority of pipelines cross at least one waterway of some type, especially the interstate lines which from start to end cross numerous bayous, canals and major rivers. These waterways...

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...

Numerical Beach Profile Modelling for Beachfill Projects
The use of beachfill in addressing coastal erosion problems is becoming increasingly popular. It is often more attractive than the conventional structural approaches for economic, aesthetic...

Hampton, New Hampshire: Beach Nourishment Project
An ongoing program of beach nourishment at Hampton Beach, Hampton, New Hampshire is a success and has resulted in long term use of a recreational facility at one of the most popular resorts...

Mitigation of Harbor Caused Shore Erosion with Beach Nourishment Delayed Mitigation, St. Joseph Harbor, MI
St. Joseph Harbor MI. was the first Corps of Engineers Section 111 erosion-mitigation project to be built. Between 1 Jun 76 and 5 Aug 85, about 1,067,000 cy of fine sand was placed in...

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...

Chesapeake Bay Field Modeling and Monitoring Projects
'Traditional' erosion control measures often do not meet the corps of Engineers' requirement for economic justification. The costs of these measures are much greater than the benefits...

Articulating Block Mat Revetment for Whaler's Village
The desire of homeowners to live along the California coastline presents the engineer with many unique design opportunities and constraints. Housing built atop coastal cliffs and bluffs...

Coastal Processes and Engineering on a Micronesian Fringing Reef
In 1980, portions of the fringing reef flat protecting the village of Tafunsak, Federated States of Micronesia, were dredged to provide fill material for an airport runway access road....

Observation of the Post-Construction Performance of a System of Groins along an Eroding Beach
A system of six groins was constructed along an eroding coast of reversing sediment transport. This paper describes the performance of the groin system in terms of the evolution of the...

Investigation of Coastal Conditions at Oregon Inlet, NC for the Replacement of the Herbert C. Bonner Bridge
The Bonner Bridge across Oregon Inlet was constructed in 1962 and is approaching the end of its service life. Planning for a future crossing must consider natural inlet migration expected...
