CANUSLANT?An Evolving-Marine Pollution Contingency Plan
The progress of CANUSLANT exercises to data is addressed in this paper. This exercise model can be used to initiate or improve Marine Pollution Contingency planning....

Coastal Zone Management in Atlantic Canada: Developing the Necessary Regional Infrastructure
This paper focuses on the incremental development of a coastal zone management (CZM) constituency in the Atlantic Region and in particular on the recent establishment of the Atlantic Coastal...

The Changjiang (Yangtze) River Delta: A Review
The Changjiang river delta is the best studied one in China in terms of hydrology, sedimentology and evolution history. The construction of Pudong New Area in Shanghai in the 1990s has...

Preliminary Study on Impacts of Sea Level Rise and Response Strategies in Japan
This paper presents the outline of the study carried out by a Japanese committee on the impacts of and response options to the anticipated sea level rise and climate change induced by...

A Study of the Water Environment Improvement about Fishing Villages
In recent years water pollution has become a serious problem in anchorage and other sea areas, as a result of residential waste water from hinterland fishing communities of fishing ports,...

Infiltration into Thick Unsaturated Alluvial Deposits: A Preliminary Study
An infiltration and dye transport study in an unsaturated alluvial deposit was conducted using a square flooding type infiltrometer over a 50 hour period. Red and blue dyes were added...

The Use of Geographic Information Systems and Models on Personal Computer and Workstation Platforms, in the Development of a Wellhead Protection Program, Salinas Valley, California
The Salinas Valley is located on California's Central Coast. The ground water basin supports 850,000,000 M² of irrigated crops which have a market...

GIS Landscape?A Solution for Wellhead Protection
Wellhead protection is an emerging issue for water suppliers based largely on the 1986 Amendments to the Federal Safe Drinking Water Act (SDWA). State governments are developing wellhead...

Uptake of Contaminants by Overland Flow
A mathematical model is developed for the uptake of contaminants by overland flow. The model is based on the numerical solution of the Navier-Stokes equations coupled with a two-equation...

Nonpoint Source Pollution Model for Agricultural and Rural Watersheds
A dynamic hydrologic and nonpoint source pollution simulation model for agricultural and rural watersheds; capable of simulating rainfall-runoff, soil erosion, sediment transport, mixing...

Urban Nonpoint Pollution Control Kettering Demonstration Project
The development of effective nonpoint pollution control programs has become one of the most complex challenges facing local and state authorities. Because of the multifarious nature of...

Irrigation, Agrichemicals and the Environmental Impact, the Role of Hydrologic Non-Point Source Models
The importance of pollution loads from agricultural lands and the degradation of soils and water resources has brought about extensive efforts throughout the environmental and agricultural...

A Review of Fluid Movement in Compacted Clay: The Case of Macropore Flow
In constructing natural hydraulic barriers to infiltration, a typical design is one founded on the use of layers of compacted clay. Unfortunately, in analyzing the hydraulic performance...

Simulation of the Propagation of Conserevative Contamination
The hydrodynamic model of the pollutant transport in water bodies was developed and adopted for Volga water supply system of Moscow, which includes five reservoirs and a channel. The model...

Water Quality Modeling of Lower Green Bay
The impact upon water quality of the planned expansion of a confined disposal facility (CDF) located in lower Green Bay was studied using numerical hydrodynamic and water quality models....

An Operational GIS to Support State-Wide Hydrologic and Nonpoint Pollution Modeling
A geographic information system(GIS) that is structured for hydrologic and nonpoint pollution modeling(GISHYDRO) became operational in the Maryland State Highway Administration's Division...

Runoff Quality Enhancements in Wet Detention Ponds
Wet detention/retention ponds are designed to reduce peak discharge and improve water quality for urban runoff. These ponds remove particulate and dissolved pollutants by sedimentation,...

Estimating Detention Pond Efficiency by a Derived Distribution Approach
The paper describes a continuation effort by the first two writers in attempting to obtain a derived distribution for the outflow pollutant mass flexes from a wet detention pond. The derivation...

Fate/Transport Modeling of Immiscible LNAPL in Unsaturated Aquifers
In the past ten years since enacting CERCLA and SARA regulations there is a lack of model to adequately address the fate/transport of immiscible constituents in groundwater systems. This...

Application of Vadose Zone Flow and Transport Models
This paper summarizes application of two subsurface flow and transport models at Superfund sites, and evaluation of a number of other unsaturated zone models. The screening level models...
