Hydraulic Resistance due to Emergent Wetland Vegetation
… hydraulic 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 …

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. …

Genomic evidence of long-term asexuality at the northern range limit of wetland plant, Decodon verticillatus (Lythraceae)
… I investigated these hypotheses in the emergent wetland plant, Decodon vertcillatus (Lythraceae), which shifts from sexual to asexual reproduction at its northern range limit. I did a de novo transcriptome assembly and compared SNPs in sexual and asexual populations at and approaching …

Groundwater and Tidal Controls on Wetland Hydrology, Julie J. Metz Wetland Mitigation Bank, Woodbridge, Virginia
<p>Julie J. Metz Wetlands Mitigation Bank, a 92-hectare freshwater wetland located in Woodbridge, Virginia, borders the tidally-influenced Neabsco Creek. Seven pods separated by earthen berms were built by Wetland Studies and Solutions Inc. (WSSI) in 1995 and 1997 by removing the toe of small sandy …

Hydrologic and topographic analyses of bog turtle (Glyptemys muhlenbergii) wetlands
… federally threatened species, depend on mountain wetland seeps to support their habitat needs. Bog turtles have been found to predominantly use saturated soil areas, making them highly sensitive to small changes in wetland hydrology. Recent research determined that water level elevations across …

Causes of the decline in the loss of vegetated palustrine wetlands in the U.S. 1955 - 2009
… States had lost over 50 percent of its original wetland resources. The U.S. National Wetland Inventory estimates that 95 percent of annual wetland losses since 1955 occurred to palustrine wetlands. The majority of these losses occurred to the three types of palustrine vegetated wetlands: …

An Evaluation of South Dakota Pheasant Preserve Habitat and Hunter Clientele
… The amount of winter cover in the form of emergent wetland vegetation was not different between preserves and controls. Shelterbelts on preserve sites tended to be of better composition for wildlife than those on control areas, with more shelterbelts of greater width, containing fruiting …

Estimating Forage Production for Waterbirds and Waterbird Response to Habitat Management at Lacreek National Wildlife Refuge, South Dakota
… height and water depths ranging from 8-16cm with emergent wetland vegetation such as Typha spp., Scirpus acutus, and Sparganium eurycarpum interspersed with 10% open water. Results of my research provides guidelines for managers in terms of habitat manipulations that may be beneficial to breeding …

Remote Sensing Methods To Classify a Desert Wetland
… de Santa Clara is a 5600 ha, anthropogenic wetland in the delta of the Colorado River in Mexico. It is the inadvertent creation of the disposal of brackish agricultural waste water from the U.S. into the intertidal zone of the river delta in Mexico, but has become an internationally …
