Professional Associations Offer Design Resources for Civil Engineers
A civil engineer is trained academically and professionally to meet the challenges and solve the problems of ever expanding world populations. With an increased demand for civil engineers...

Industry Standards for Erosion Control Products�Future Tools for Civil Engineers
In 1990, the International Erosion Control Association (IECA) formed a Cooperative Standards Program (CSP), directed by the IECA Committee on Standards. The purpose of the CSP is to develop...

Stream Instability in Loess Base Channels
The incision of bess base stream channels is a common and destructive response to alterations within a watershed in the midwest. Monitoring and evaluating procedures are being performed...

Managing the Impacts of Storm Surges on Victoria Island, Lagos, Nigeria
Victoria Island is one of the barrier islands along the Nigerian Coast. The others are Lagos, Lekki, Ikovi, and Badagry. A general characteristic of these barrier islands in Nigeria is...

Channel Restoration Project along Toby Creek
Creek banks within Mecklenburg County, NC, are eroding, producing excessive quantities of sediment in the creek and causing bank instability. Seeking innovative approaches to these problems,...

A Comparison of Sediment Routing Models
In this paper the authors have compared the performance of coupled linear and non-linear methods of solution from these generic types, in order to assess their suitability for use in optimisation...

Propeller Wash Induced Erosion at Quay Walls
The characteristics are examined of the sea bed erosion produced by the scouring action of a ship's propeller wash acting against a quay wall. The rate of development of erosion...

Dam Foundation Erosion Study: Pit 4 Scale Model Simulation
This paper describes the results of a sub task of the Dam Foundation Erosion Study, a cooperative research study by Reclamation, PG&E, Colorado State University, and Western Area...

On Silt Abrasion Erosion of Three Gorges Hydraulic Turbine in the Future
In this paper the basic parameters of Three Gorges hydraulic turbine have been reviewed and the operation characteristics of Three Gorges hydropower Station pointed out. Combined with...

Sediment Erosion Rate in the Baltimore Harbor
In-situ erosion experiments were conducted at four selected sites in the Baltimore harbor in May 1995 using the VIMS Sea Carousel. The measurements showed that the erosion rate decreased...

Scour Power
New prediction methods consistently calculate scour around bridge piers allowing engineers to better tailor pier design in rock and consolidated material. The leading cause of bridge failure...

For Sure Shores
Fighting a long history of beach-destroying structures and man-made inlets, coastal engineers are finding that the answer to beach erosion lies in a deeper understanding of its dynamic...

Overview of Space Environmental Effects
The natural environment for low Earth orbit subjects satellites to various forms of damage, ranging from particulate impacts, ultraviolet light, atomic oxygen erosion and charged particle...

Applications of Large Domain Hydrodynamic Models to Generate Frequency-of-Occurrence Relationships
This paper describes theory and application of the Empirical Simulation Technique (EST), a statistical procedure for simulating time sequencing and frequency-of-occurrence relationships...

Wave Attenuation at the Mobile Stable Berm
This paper describes work examining the ability of submerged berms to `filter' certain erosive wave energy while allowing accretionary type waves to pass unhindered. Analysis of wave data...

Using Drop Structures for Stream Gaging
A long term monitoring program of 15 watersheds, for the purpose of studying channel response to erosion control measures being constructed in north Mississippi, is being conducted by...

A New Basic Principle for a New Series of Hydraulic Measurements. Erosion by Abrasion, Corrosion, Cavitation and Sediment Concentration
The DECAVER is a novel apparatus able to make new measurements in various domains where an erosion is produced in an aqueous medium. It gives the erosion rate and the accumulated erosion....

On the Erodibility of Rock and Other Earth Materials
An outline of a new method to determine the erodibility of rock and other earth and engineered earth material is presented. The method quantifies the relative capacity of the boundary...

Benefits of Hazard Mitigation Planning to Reduce Shoreline Impacts Due to Great Lakes Water Level Management Fluctuations and Severe Storms
Recent experience with flood hazard mitigation planning that encompassed aspects of pre-disaster preparedness and recovery operations have proven to be an effective tool in geographic...

Mathematical Models to Assess Stream Dynamics
A methodology is proposed to predict the behavior of meandering streams. Using a stream-shift model, lateral channel shift over a period of time is computed for several reaches with the...
