Tampa Bay 205J Water Quality Impact Study
Tampa Bay was identified by the State of Florida Department of Environmental Regulation (FDER) as to the top priority for an impact study using federal 205(j) grant funding. The study...

Groundwater Modelling
The numerical simulation of groundwater flow and transport has evolved from a technical curiosity to an established method of hydrological analysis. In this brief review the progress that...

Numerical Modeling of Groundwater-Lake Systems
Groundwater inflows can have important effects on the chemistry and biology of a lake ecosystem. For example, studies of lakes in Northern Wisconsin documented localization of ferromanganese...

Utilization of Numerical Models in Groundwater
For many years numerical models have been used in groundwater hydrology. In a recent assessment of the availabilty and use of models, a number of problem areas were identified. Some of...

Risk Assessment for Groundwater Contamination: I
This paper constitutes Part I of a two-part article. Both parts focus on the risk assessment and management process in terms of the ever-present problem of groundwater contamination and...

Risk Assessment for Groundwater Contamination: II
This paper constitutes Part II of a two-part article. Both parts focus on the risk assessment and management process in terms of the ever-present problem of groundwater contamination and...

Water Quality Modeling of Key Largo Coral Reef
A numerical model called CORALSIM has been developed for the Key Largo Coral Reef National Marine Sanctuary in the Florida Keys. The model was developed as a management tool to study the...

Digital Simulation of Flows in Hawaiian Soils
In attempting to numerically solve the nonlinear equation for flows in porous media, the Galerkin process, which bears a great similarity to direct methods of the calculus of variations,...

Use of a Two-Dimensional Flow Model to Quantify Aquatic Habitat
This paper describes the use of a numerical two-dimensional flow model to evaluate the impacts of potential hydropower retrofits on downstream flow distributions at Lock and Dam No. 8...

Simultaneous Withdrawal of Saline/Fresh Waters in a Stratified Aquifer
The objective of this study is to develop computational tools for simulating the flow behavior of an aquifer in response to simultaneous pumping of two stratified fluids from both sides...

Development of a Demand Management Plan for Greater Boston
The Metropolitan District Commission (MDC) in Boston is preparing a long-term water supply plan for its present and potential service area. The MDC is committed to a program of water conservation...

A Stepwise Approach to Environmental Systems Maintenance Management
This paper provides a systematic approach to establishing a maintenance management program for environmental infrastructure. It begins by discussing the definition of program objectives,...

Denver's Dual Utilization Sludge Management Plan
The Metropolitan Denver Sewage Disposal District No. 1 (District) has adopted a Dual Utilization approach to sludge management. This technique uses composting during periods of inclement...

Environmental Auditing ? A Management Tool
This paper discusses environmental auditing as implemented within the Aluminum Company of America (Alcoa) and focuses on auditing as a management tool. The program is covered from its...

Environmental Auditing As a Management Tool
The authors define environmental auditing, explain the purposes of auditing, and describe an audit approach....

Geothermal Salt Recovery From Evaporating Ponds
The water from geothermal reservoir 'Los Azufres' in Michoacan, Mexico, is characterized by its high content of chloride, silica, borum and arsenic. Due to the...

Roller Compacted Concrete
Roller compacted concrete has emerged recently as an economical material and rapid method of construction for use in gravity dams, overflow structures and heavy duty pavements. The economics...

Economics of Ditch Maintenance in Northwestern Ohio
A history of drainage and settlement in the Black Swamp of Northwestern Ohio is presented. The Ohio Ditch Law and county ditch maintenance program is explained. An economic comparison...

Innovative Management in a Period of Austerity: The Glamorgan Heritage Cost Experience in the U.K.
Restraint in UK economic growth gave rise to a new countryside management approach which was non-statutory, dependent upon voluntary agreements. In essence the land remains in private...

Formation of a Caribbean Coastal Management Unit
Rational management of Caribbean coastal areas is hindered by the poor state of knowledge of coastal ecosystems and by shortage of manpower with expertise in coastal management. To address...
