Modeling Water Table Response to Climate Change in a Norther Minnesota Peatland
Projections of global warming raise questions concerning the fate of wetlands in many parts of the world. In northern Minnesota, there is concern that the nearly 3 million hectares of...

Point Precipitation Models to Simulate Water Balance at a Constructed Wetland
We compare two point precipitation models in a water balance simulation performed at a wetland constructed to treat municipal wastewater. The first precipitation model uses a simple Poisson...

Flow Patterns in Constructed Wetlands
Wetland water flow is sensitive to evapotranspiration and rainfall, and to the internal configuration of substrates and biota. All wetlands are subject to significant dead zones and bypassing....

Fundamental Principles of Tidal Wetland Restoration
Recognition of the vital role of tidal wetlands for sustaining migratory bird life, for indigenous animal habitat, and for the fishery of contiguous waters has stimulated efforts to restore...

Integrated Description of Wetland Hydrology and Ecology by Mathematical Models
The agricultural utilization of the natural zone between the terrestrial and the aquatic system has reduced these important bufferzones in the last 30 years. The use of wetlands as nutrient...

Refined Modelling of Water Quality Constituents in a Semi-Enclosed Coastal Wetland Basin
Details are given of the refinements to a numerical model to improve the representation of the advective transport of water quality constituents. The higher order accurate scheme adopted...

Orange County Florida Landfill Dilute Leachate Wetland Treatment and Restoration System
The Orange County Landfill began operation in 1971 as an EPA demonstration project for the purpose of defining landfill operations in high groundwater table areas. To prevent groundwater...

Environmental Control of Wetland Plant Communities
We have determined hydrologic regimes at a variety of sites while conducting studies to identify factors controlling wetland plant community composition and distribution. We have had relatively...

Variability of Hydraulic Response of Constructed Wetlands
Dye tracer studies using Rhodamine WT have been performed on two field scale subsurface flow wetland units for further improvement of secondary treated municipal effluent at Byron Bay...

Wetland Management in Britain: A Comparative Approach
Wetland management in the United Kingdom is in an early stage of development. The importation of management aims and techniques from other countries with more advanced programmes is an...

A Hydrodynamic Model for a Tidal Wetland
A hydrodynamic model is developed for San Elijo Lagoon, a wetland with tidally influenced area of 1.5 km2 (380 acres). A quasi two-dimensional (2-D)...

Annual Oscillation of Mean Monthly Water Levels at U.S. Ports
The annual variation in water level is not widely recognized among engineers. It could effect the selection of design ship channel depth or marina channel dredging, and tidal wetland creation...

Extreme Events and Coastal Wetlands
Temporal ecosystem behavior in tidal wetlands can be static, dynamically stable, progressively changing, or subject to catastrophic change during extreme events. Catastrophic change in...

Yolo Bypass Wetlands?Impact Investigation
Approximately 20 square kilometers of wetland facilities are proposed to be installed within the Yolo Bypass of the Sacramento River Flood Control Project. A hydraulic impact investigation...

Management of Rice Fields for Wetlands, Water, and Rice Production
The feasibility of managing a portion of the Sacramento Valley's rice fields as wetlands for waterfowl use, storage, and aid in rice straw decomposition was evaluated. Approximately 95%...

Wetland Conservation Plans as Contexts for Transportation Planning
Construction of major, new roadways, particularly in metropolitan areas, initiates subsidiary affects that impact the environment in a variety of ways and increasingly over time. Not the...

Coastal Zone '93
Coastal Zone 93, held in New Orleans, Louisiana, July 19-23, 1993, is the eighth in a series of biennial multidisciplinary symposia on comprehensive coastal and ocean management. The papers...

Hydraulic Engineering
This proceedings, Hydraulic Engineering, contains papers presented at the 1993 National Conference on Hydraulic Engineering held in San Francisco,...

Reclaiming Clear-Cut Land
The Savannah (Ga.) Airport Commission needed to expand the city's international airport to meet projected needs through 2007. The expansion was designed with Greiner, Inc.,...

The Big No-Dig
As part of the Boston Harbor cleanup project, engineers will have the opportunity to make a rare, side-by-side comparison of open-cut construction and no-dig technology during the Wellesley...
