Development of a Wetland/Riparian Resource Model for the Missouri River System
Wetlands and riparian areas are significant resources along the Missouri River, providing important fish and wildlife habitat. These resources required evaluation as part of the review...

Missouri River Least Tern and Piping Plover Model Development
As part of the update of the Missouri River Master Water Control Manual, the U.S. Army Corps of Engineers is evaluating the effects of numerous water management alternatives on endangered...

Modeling Pollutant Fate and Transport in Constructed Wetlands
The Constructed Wetlands Fate and Aquatic Transport Evaluation Model (CWFATE) was developed to evaluate alternative design and operations of the constructed wetlands treatment system (CWTS)...

Floodflow Effects on Riparian Vegetation in Arizona
A relation for estimating changes in the condition of riparian vegetation as a function of stream power was developed for stream channels in central Arizona. Flood and vegetation data...

Roughness Coefficients for High-Gradient Channels in New York State
Manning's roughness coefficients (n values) were computed for a range of flows at six streams in New York State (USA) that have high energy gradients (greater than 0.002) and large median...

Width Adjustment: Relative Dominance in Unstable Alluvial Streams
The mechanisms that control the relative dominance of width adjustment in unstable streams are described. Specifically, the role of the following factors affecting the fluvial environment...

Costs and Benefits of Meeting the San Francisco Bay Copper Objective by Regulating Small Treatment Plants
Metals in aquatic environments, even in very small amounts, are of concern because of potential toxicity to aquatic life forms. Copper is of particular concern in the San Francisco Bay...

A Highway Maintenance Operation Database
This paper presents the major findings of a study to develop a system design for the implementation of an electronic network which uses personal computers in local highway maintenance...

A Methodology for the Evaluation of Global Warming Impact on Soil Moisture and Runoff
Global warming is expected to increase the intensity of the global hydrologic cycle. Precipitation and temperature patterns, soil moisture requirements, and the physical structure of the...

Ecological Considerations in Groundwater Management
A wide variety of potential effects of groundwater management on terrestrial vegetation and aquatic biota are described and illustrated with examples from California....

Effects of Reservoir Management on Establishment of Riparian and Wetland Vegetation in Northeastern Washington
The effects of various reservoir pool management scenarios on the establishment of riparian and wetland vegetation in arid regions of the Pacific Northwest are discussed. This study quantifies...

Competitive Advantage of Using Computers in Structural Design
More and more structural analysis and design work is done using computers. The trend will continue because the software is becoming more powerful and the cost of computers is falling....

Towards a `Simple' Long Term Evaluation of HSGT
The author examines, analyzes, and pursues the roots of several fundamental economic and related theories and techniques commonly used to determine technological performance, its measurement...

Are Landscape Patterns Related to Marsh Loss Processes?
Marsh loss that occurs in Louisiana is seldom associated with shoreline erosion of lakes and bayous; instead, marshes break up internally. Marsh loss is attributed to processes that stress...

Production and Decomposition of Spartina patens in a Degrading Coastal Marsh
Production and decomposition rates were calculated for Spartina patens in a mesohaline coastal marsh in Louisiana. Production was estimated to be 800 g m-2 ur-1 during 1991 and 1,696 g...

Plant Establishment Enhancement Technique for Shoreline Stabilization and Protection
Once established, vegetation is capable of significantly reducing erosion along streams, rivers, bays, sounds and other tidal shorelines. In the last 15 years, many attempts to establish...

People and Resources Within the Barataria-Terrebonne National Estuary
South Louisiana's geographic complex is a product of two discrete ingredients: one natural and the other cultural, or human. Relief, soils, landforms, rocks, vegetation, climate, and other...

Using GIS to Monitor Wetlands Loss/Gain
This paper represents the work being done at the National Wetlands Research Center (NWRC) for the U.S. Army Corps of Engineers (COE) to monitor wetland change in the Mississippi River...

Traffic and Lead Pollution on Lake Maracaibo's Western Coast
This project focused on Nerium Oleander (NO) (Berberia), an ornamental plant. Chemical analyses (acid digestion and atomic absorption spectrophotometry) of the plant's tissue and the soil...

Effects of Surface Brine Disposal on the Marshes in Coastal Louisiana
In 1986, more than 1 billion barrels of brine were disposed of in Coastal Louisiana. Disposal of brine into surface water body is economically practical but environmentally detrimental....
