River Meander Zones and Floodplain Reconnection
A natural disturbance regime concept is described for understanding ecosystem changes due to human activities. Re-establishment of river meander zones is proposed as an application of...

Design Guidance?Instream and Bank Restoration Structures
Despite an urgent need for river and stream restoration design criteria, little guidance has emerged in recent years. Existing guidance is largely unsatisfactory, promoting empiricism...

Ecosystem Management in the State of Florida
The Florida Department of Environmental Protection (DEP), acting at the direction of the 1993 legislature and the Governor, has developed a concept for implementing ecosystem management...

Modeling Combined Stresses on Aquatic Ecosystems
A mechanistic ecosystem response model is being developed by incorporating exposure/response relationships for selected natural and anthropogenic stresses into an existing hydrodynamic...

The Potential for the Department of Defense to Use Space-Based Remote Sensing to Support DOD and Other Government Agencies' Environmental Programs
This paper describes the potential for the Department of Defense (DOD) to support other government agencies in the management of national and worldwide environmental programs. The DOD...

Biosphere II - Its Effects on Space Colonization
In the middle of the Arizona desert, a strange sight can be seen. A small world with ecosystems and different climate zones, just like Earth, is enclosed in glass and steel. The 3.15 acre...

Impacts of Natural and Manmade Changes on the San Luis Rey River Environment
Almost all rivers continually change their position and shape based on various geomorphic and hydraulic factors, caused by natural as well as manmade activities on the riverine environment....

The Role of Partnering and Public Involvement in the Lackawanna River Corridor Greenway Study
Development of partnerships and active public involvement programs has, in the past, been de-emphasized for the more traditional Corps studies. However, as the Corps continues to progress...

Technical Understanding in Successful Environmental Negotiations
Scientists at the National Ecology Research Center conducted a series of case studies of consultations concerning the environmental conditions to be included in Federal Energy Regulatory...

Water Polishing by Constructed Wetland Ecosystems
This paper gives results of a five-year study of minerals and nutrients reduction in a large constructed wetland facility in Central Florida, on the periphery of Orlando. The 120 ha system...

Riparian Wetlands and Flood Stages
The paper studies concurrent flood stage records from two fourth-order streams in the hills of northwest Mississippi with similar soils, watershed relief and overall land use. The streams...

Instream and Streambank Environmental Feature Guidelines
Tightened regulatory requirements and a renewed appreciation for the benefits of preserving our diminishing natural resources have led to a recent profusion of stream restoration projects...

Assessing Stormwater Impacts
The evaluation of stormwater effects to watershed ecosystems must adopt an integrated approach due to the inherent complexity of assessing such environments, arising from the vulnerability...

Why Design Storm Methods Have Become Unethical
This paper discriminates between continuous and event modelling, and describes some dimensions of ethical design for sustainable ecosystems. Arguments are presented that event modelling...

Modeling Ecological Impacts of Destratification
Artificial destratification has long been advocated as a means of improving water quality in lakes and reservoirs. The results have been varied with examples of both water quality improvement...
