A physical and natural resource survey was conducted of the ponds and lagoons on Horn and Petit Bois Islands, Gulf Islands National Seashore, Mississippi. Petit Bois Island contains 17...

Status of the Spiny Lobster (Crustacea: Palinuridae) Stocks Off Northeast Brazil in Relation to Fishing Effort and Environmental Conditions
Conditions for the development of relatively abundant populations of spiny lobsters of genus Panulirus, mainly P. argus and P. laevicauda, off Northeast Brazil are consistent with hydrologically...

Tourism Versus Conservation in Fernando De Noronha Island, Brazil
Conscious of the problems created by tourism expansion and searching for a definition of the uses compatible to the restoration and the maintenance of ecological equilibrium, the previous...

Impact on a Primitive Fishing Community in Maric? County, Caused by Urbanization
The fishing communities studied in this paper, although influenced by the more important urban growth movement of the metropolis of Rio de Janeiro, have reacted in a different manner to...

Automated Design of Wastewater Plants
Computers have been used for individual steps in design of wastewater treatment plants, and now these steps have been tied together, linked by an aggregate computer program the designers...

Frame Based Expert Systems?The Clear Choice for CAPP Systems
This paper gives a brief overview of Computer Aided Process Planning (CAPP) systems. We attempt to examine some of the representational problems specifically associated with production...

Expert Systems for Assessment of Radon Gas
This paper covers a brief discussion of enviro-geotechnical aspects of radioactive toxic radon gas. Basic information required for assessment and controlling this gas is summarized and...

The Distribution of PCB Contaminated Sediment in the Kalamazoo River Valley, Michigan
Heightened environmental awareness beginning in the 1970s focused upon lowering contaminant levels in the Kalamazoo River system through the improvement of water quality. The Michigan...

Generating Instream Recreational Alternatives
A methodology combining an optimization model and a spreadsheet program is presented to assist resource managers in developing and evaluating instream recreational alternatives. Recreational...

Methodologies to Estimate Instream Benefits for Use in Water Allocation
In the 'utility valuation' approach, the recreational experience possible at given flow levels is examined to derive a utility that the resource provides to the...

Generation of Compromise Alternatives Between Maximum Benefits and Maximum Acceptance
This paper proposes a procedure to generate a set of compromise alternative solutions between maximization of benefits and maximization of acceptance. A small set of near optimal strategies,...

Southeastern Drought of 1988?A Federal Perspective
The drought that has plagued the Southeastern United States for most of the 1980's is continuing in two major river basins within the geographic boundaries of the South Atlantic...

People and Practicality in Water Management
A discussion of the water control management responsibilities of the St. Louis District, U.S. Army Corps of Engineers, is given, with particular emphasis upon people issues and upon practical...

Instream Flows for Recreational and Aesthetic Resources
Methods for assessing impacts of instream flow changes on recreation and aesthetics are presented. Impacts to recreation can be predicted by quantifying recreational use, predicting impacts...

Knowledge-Based Real-Time Management of Risk Processes
A project proposed to the Commission of European Communities within the framework of the European Strategic Program in Research and Information Technology (ESPRIT) aims at the development...

Baseflow and Beta Distribution
For water resources projects, design engineers are often required to separate total flow into baseflow and direct runoff. During such studies, baseflow is considered a crucial parameter;...

Climate Change and U.S. Water Resources: Results from a Study by the American Association for Advancement of Science
The time horizon of the changes that might occur is similar to the time required for planning, approval, funding, construction and economic life of such major water facilities as dams,...

Utilization of Expert Systems for the Operation of Reservoir Systems
This paper illustrates how knowledge-based expert systems can obtain, organize, document, store, and utilize valuable complex reservoir systems experience, obtained by experienced water...

IJC Challenges in an Era of Uncertainty
Since its creation pursuant to the 1909 Boundary Waters Treaty between the United States and Canada, the International Joint Commission (IJC) has evolved into an effective mechanism for...
