Influence of a Sand Layer on Headcut Advance
The presence of an erodible material layer in the soil profile has been observed to influence headcut movement in earth emergency spillways. Large-scale flume tests were conducted to examine...

Monitoring and Modeling the Transport of Coarse Single Particles in Mountain Rivers
The dynamics of single cobbles was studied in the alpine river Lainbach using the Magnetic Tracer Technique (MATT) and radiotransmitters (PETSY = PEbble Transmitter SYstem). Our measurements...

Erosion and Deposition by Debris Flows in Mountainous Channels on North Fork Mountain, Eastern West Virginia
A study of four debris-flow impacted channels in the North Fork Mountain area of eastern West Virginia shows that the geomorphic effect of debris flows on channel morphology is variable...

Equilibrium Geometry of Channels with Cohesive Banks
An optimization model is used to assess the stability of gravel-bed rivers with cohesive channel banks and to determine the effect of the bank stability on the equilibrium hydraulic geometry....

Protecting a Pipeline
A 30-inch oil pipeline, presently under construction through mountainous terrain in central Colombia, transports petroleum from the Cusiana oil field to the coast. The discovery of the...

Prediction of Embankment Dam Breaching for Hazard Assessment
Downstream hazard assessments for dams require prediction of 1) whether a breach could form, and 2) the hydraulic characteristics of the breach for use in calculations of discharge and...

Saylorville Spillway: Emergency to Service Spillway
The spillway for Saylorville Lake located on the Des Moines River, 12 miles north of the city of Des Moines, Iowa, a large metropolitan, was designed as an emergency spillway. Due to subsequent...

Rehabilitation of a Toe Drain
Old or improperly designed toe drains can cause trouble for embankment dams. Toe drains installed without proper filtering can provide an easy course for internal erosion and piping of...

Geotechnical Modifications at Meeks Cabin Dam
This paper presents a summary of the geologic and geotechnical evaluation of a potential piping deficiency identified at Meeks Cabin Dam as well as description of remedial measures and/or...

Double Rock Park Stream Restoration Project
The Double Rock Park stream restoration is a pilot project for the Baltimore County, Maryland, Stream Restoration Program. The study assessed watershed conditions and the stream channel...

Coastal Erosion and Protection in China
The recent coastal erosion in China was becoming increasingly remarkable in the late fifties and had taken a turn for the worse in the late seventies. At present there exist about 70 per...

Are Landscape Patterns Related to Marsh Loss Processes?
Marsh loss that occurs in Louisiana is seldom associated with shoreline erosion of lakes and bayous; instead, marshes break up internally. Marsh loss is attributed to processes that stress...

Holocene Sedimentation and Coastal Wetlands Response to Rising Sea Level at the Aucilla River Mouth, a Low Energy Coast in the Big Bend Area of Florida
The shallow dip of the Florida carbonate platform results in low wave energy on Florida Big Bend coasts. Therefore sedimentation is dominated by river-and tidal-hydrodynamics near the...

Plant Establishment Enhancement Technique for Shoreline Stabilization and Protection
Once established, vegetation is capable of significantly reducing erosion along streams, rivers, bays, sounds and other tidal shorelines. In the last 15 years, many attempts to establish...

Washington State Coastal Erosion Management Strategy
The shores of Washington's inland coast - Puget Sound - undergo chronic and episodic erosion and landsliding. The problem is not nearly so great here as elsewhere in the U.S.A., but what...

Predicting Impacts of Management Measures on Fragile Coastal Wetlands Using a Predictive Landscape Model
We present a marsh development model that incorporates the hydrodynamics of erosion and sedimentation and meets all conventions proposed for spatial landscape modeling. Wave parameters...

Theoretical Study of Artificial Nourishment on the Suape Beach, State of Pernambuco, Brazil
This paper describes the theoretical studies developed to design the artificial nourishment on Suape Beach, State of Pernambuco, Brazil. The basis concepts are briefly discussed, as well...

The Economics of Managing Coastal Erosion
In the race to develop prime coastal land, many structures have been built in high hazard areas which are prone to coastal erosion. In a real sense, erosion is not generally viewed to...

Managing Beach Erosion in Fortaleza, Brazil
The littoral of the metropolitan region of Fortaleza City, State of Ceara in the Northeastern part of Brazil, has suffered significant morphological changes during this century. There...

Beach Stability and Coastal Erosion in the Eastern Caribbean Islands-A Regional Programme
The problems associated with coastal erosion have been facing the smaller islands of the Eastern Caribbean for many years. The skills necessary to manage the problems have not been available...
