Simulation of the Quasi-Static Deformation of 2D Assemblages of Rigid Discs
Although the importance of dilatancy in the constitutive behaviour of granular materials has been recognized for some time, conclusions about its evolution and dependence on different...

Interparticle Sliding and Rolling
Numerical experiments are done with a continuum plasticity program in order to study the initiation and evolution of shear bands. Many elements are used in order to resolve families of...

Computer-Monitored Grouting
With grouting operations going on at many locations around the clock on a typical large dam-foundation project, how do you make sure that the designed mix is always being used and as-built...

Flows of Hazardous Materials Through States by Rail
This paper presents information on the tonnages of hazardous materials passing through each of the contiguous 48 states (and the District of Columbia) by rail. The quantities are estimated...

Measurements of Nutrient and Metal Fluxes from the Sea Floor in the Area Around the Whites Point Sewage Outfall, Los Angeles, California
Studies are underway to determine the influence of sewage outfall-impacted sediment on the exchange of nutrients and trace metals in the coastal marine environment. Utilizing a benthic...

Dynamic Flushing of Pocket Marinas
The expanding demand for marina space combined with just concerns for the coastal environment has developed an urgent need for methods for evaluation of the flushing characteristics of...

Experiments on Stratified Flows: A Comparison with Theory
Stratified flows caused by salt wedges in estuaries, fjord flows and power station cooling waters represent very complicated flow situations with regard to their stability and rates of...

Estuarine Tropical Forcing Functions: The Palizada River Delta (Southern Gulf of Mexico), a Case Study
The geomorphological characteristics of the fluvial - deltaic - lagoon - estuarine system of Palizada River (FDLESPR) in the southern Gulf of Mexico, allows the interaction of several...

The Tidewater Ecobotanical Garden: Lessons in Preserving, Restoring, and Interpreting Forested Coastal Wetlands
The West Neck Creek and North Landing River systems of the City of Virginia Beach are representative examples of the northern coastal margin of the Mid-Atlantic Tidewater. A 580 acre municipally-owned...

Modeling of Salt-Water Intrusion in River Mouth Region
By considering the fresh water and salt water as different phases in a two-phase flow system, a set of equations are given for describing the salt-water intrusion as well as the mixing...

Environmental Impact on Sepetiba Beach
This paper describes the erosive and sedimentary processes which have been causing damage to the most important beach on Sepetiba Bay in Brazil. Remote sensing techniques and data obtained...

Implementation of the North Fraser Harbour Environmental Management Plan
Since 1913, The North Fraser Harbour Commission (NFHC) has been responsible for administering the Port of North Fraser. This responsibility is especially challenging because the port is...

A Zoning Code Revision for Port Development?The Story of East Providence
The City of East Providence evaluated the effectiveness of the City's 30 year old zoning code and revised performance standards in the zoning text in light of possible marine...

Observations of Seasonal and Interseasonal Variability in Shelikof Strait, Alaska
Nearly five years of monthly mean current data from two locations (one nearshore on the shallow shelf and one in the Shelikof sea valley) are used in conjunction with surface geostrophic...

Recreational Impacts on Coastal Habitats: Ventura County Fairgrounds, California
The doubling of California's population since 1960 has presented new challenges to the California Coastal Act's mandates to maximize public coastal access and...

Distribution and Developing Trace of Productive Forces in China Coastal Development Zones
Following the setting up of special economic zones in 1979 and the opening of the 14 coastal port cities in 1984 in China, 14 economic and technological development zones were set up one...
