A Checklist Assessment of Dune Vulnerability and Protection in Devon and Cornwall, UK
Various indices have been utilised as a measure of dune vulnerability both to natural and anthropogenic forces. To date most have had little success with respect to quantitatively assessing...
Smoke Plumes From In Situ Burning of Oil Spills
Mesoscale pool fire experiments with effective diameters up to 17.2 m were conducted to obtain data on the characteristics of burning crude oil on water. These experiments showed that...
Data Collection Program for the Design of a Wetlands Restoration Project
In this paper, a data collection program developed for wetland restoration projects in Southern California is described. The program will include itemized parameters in a checklist-type...
Pitzunda Peninsula Coast Dynamics
The dynamics of Pitzunda Peninsula during last 100 years is examined in this paper. The process of sediment shift and coastline evolution during last 30 years is considered in detail....
Development of the Double Cylinder Caisson Breakwater
A double cylinder caisson breakwater was recently developed to create a calm sea area in deep and high wave open sea areas. In order to confirm some subjects on design method and construction...
Field Implementation and Testing of a Machine Vision Based Incident Detection System
This paper contains test results of a video detection device installed in the field for over two years and the development and field deployment of an incident detection sysytems called...
Motorist Aid Systems ? Intelligent Roadside Controllers
Advanced technology call boxes, employing a variety of communications networks and embedded microprocessors, have brought a new level of functionality and extensibility to motorists aid...
Univeral System Architecture ? Based on European Field Trials
From the ongoing major IVHS/RIT operational field tests in Europe and taking into account the results of the 3 years Berlin field trial LISB it can be assumed that the winning communications...
Simulation-Based Training for Transportation Management Center (TMC) Operators
Effective simulation-based training for Transportation Management Center (TMC) operators enables operators to make the best use of their TMC and thereby to improve the efficiency and safety...
Infiltration in Two Sand Dune Areas in Saudi Arabia
Field infiltration experiments at several locations in two sand dune areas in Saudi Arabia were conducted. Results of these field tests are compared with predictions of the Green and Ampt...
Hydrology of Wetland Treatment Systems in East Orange County, Florida
Wetlands are increasingly being used as final treatment systems for industrial and domestic wastewater effluent discharges and stormwater runoff discharges. Hydrological monitoring and...
Non-Intrusive Crack Detection in Clay Landfill Cover Liners
Laboratory and field studies were conducted to demonstrate that the azimuthal variation in electrical resistivity can be used to indicate the presence of cracks in clay systems. Laboratory...
In Situ Bioremediation Via Horizontal Wells
The U.S. Department of Energy, Office of Technology Development, has been sponsoring full-scale environmental restoration technology demonstrations for the past 3 years. The Savannah River...
A Semi Passive Nutrient Injection System for In Situ Bioremediation
A permeable cutoff wall is installed across the path of a contaminant plume. The water in the wall can be amended with the desired nutrient solution using pumping and injecting wells within...
In-Situ Bioremediation Using a Recirculation Well
An existing model (Semprini and McCarty, 1991; 1992) of in-situ bioremediation using methanotrophic bacteria for degradation of volatile organic compounds was modified to simulate use...
Modelling Studies of Gas Venting and Steam Injection for NAPL Site Remediation
A fully coupled, fully implicit method for simulating gas injection and steam injection for in situ remediation of sites contaminated with volatile NAPL is presented. Numerical results...
Field-Scale Research at the TVA Columbus Groundwater Research Test Site
TVA has been conducting large-scale field experiments at their Columbus Groundwater Research test site at Columbus Air Force Base since 1983. This work has been performed in cooperation...
River Characteristics of the Blue Nile Watershed
A common difficulty in modeling hydrological systems is the lack of available field data to assess the model parameters. In some cases, it is physically very difficult and expensive to...
Nitrogen and Phosphate in Vadose Waters in Heber Valley
During the last decade best management practices have been gradually implemented in Heber Valley to maintain and enhance the qualities of surface waters that flow into Deer Creek Reservoir....
Sediment Entrapment by Stream Channel Vegetation
Degraded headwater streams are common in the mountainous West. They have experienced a variety of stresses from public and private uses and will require specific management consideration...
