Evaluation of a Water Budget Model for Use in Wetland Design
Wetland ecological function greatly depends on the wetland hydrology. As a result, correctly estimating the wetland water budget, is essential to the success of created wetlands. A wetland water budget model, Wetbud, was developed by collaborators from Virginia Tech, Old Dominion University, and …

Evaluation of a Water Budget Model for Created Wetland Design and Comparative Natural Wetland Hydroperiods
Wetland impacts in the Mid-Atlantic USA are frequently mitigated via wetland creation in former uplands. Regulatory approval requires a site-specific water budget that predicts the annual water level regime (hydroperiod). However, many studies of created wetlands indicate that post-construction …

Surface water flow resistance due to emergent wetland vegetation
The key to a successful wetland design is duplicating the hydroperiod of the desired wetland type. Dense wetland vegetation affects surface water flow rates by increasing flow resistance. Prior research represented the vegetation as individual stems; however, many wetland species grow in clumps. …

The technical and economic feasibility of constructing an artificial wetland for Burra-Burra Creek in Ducktown Tennessee
… in the immediate area. The use of constructed wetlands to treat acidic mine seepage was explored aggressively in the 1980's. Several artificial wetlands were constructed and some guidelines for wetlands design were developed. These guidelines were neither consistent with each other nor widely …

Flow estimation for stream restoration and wetland projects in ungaged watersheds using continuous simulation modeling
… technique for estimating a single or range of design discharges is the generalization of a parsimonious conceptual continuous simulation model. In this study the Probability Distributed Model (PDM), was generalized for the Maryland and Virginia Piedmont. Two hundred and sixty years of daily …

Evaluating a Process-Based Mitigation Wetland Water Budget Model
… water levels is key to the success of created wetlands. The Pierce method is a commonly used technique for modeling and designing mitigation wetlands that assumes minimal groundwater interaction with the wetland. This technique for mitigation wetland design relies primarily on surface water …

Energetics of Turbulence Explains Physical Transport Processes in the Environment
… as river restoration, sediment transport, and wetland design, is a widely acknowledged fact. Notably, turbulent eddies exert a substantial influence on transport phenomena, warranting novel approaches that account for their energetic impact on bulk flow variables. In this vein, the present …

Hydraulic Resistance due to Emergent Wetland Vegetation
… resistance due to vegetation in emergent wetlands are crucial to wetland design and management. Hydraulic models that consider vegetation rely on an accurate determination of a resistance parameter such as a friction factor or a bulk drag coefficient. At low Reynolds numbers typical of …
