Experimental Study on Wetland Hydraulic Characteristics of Vegetated Drainage Ditches
Small vegetated drainage ditches play an important role in water and nutrient removal, but may cause water blocking problems. The aim of this study was to investigate vegetated drainage ditches’ hydraulic and wetland hydraulic characters. Field experiment were carried out, small drainage ditches with Juncus, Zizania latifolia, and Acorus calamus were selected under different water flows, and a ...
متن کاملConsequences of Prairie Wetland Drainage for Crustacean Biodiversity and Metapopulations
Much of Illinois was once wet prairie, dotted with ancient (ca. 10,000-year-old) ephemeral wetlands. Most wetland habitat (85%) was converted to agriculture over a span of about 100 years (ca. 1850– 1950). The consequences of this severe habitat fragmentation on wetland communities and metapopulations are unknown. We studied crustacean communities (weekly stovepipe samples throughout hydroperio...
متن کاملDIVISION S-10-WETLAND SOILS Wetland Soils — Opportunities and Challenges
Wetlands are an important natural resource in the biosphere. Traditional terms used to describe wetlands are marshes, bogs, and swamps. Early European settlers considered these areas as wastelands and did not appreciate their values. For a number of years, many of these areas were drained and used as farmland, since these lands were found to be productive. Over a 200-yr time span (1780-1980), t...
متن کاملConstructed Wetland Treatment Plant Constructed Wetland Microbial Fuel Cells
18 This work aimed at determining the amount of energy that can be harvested by 19 implementing microbial fuel cells (MFC) in horizontal subsurface constructed wetlands 20 (HSSF CWs) during the treatment of real domestic wastewater. To this aim, MFC were 21 implemented in a pilot plant based on two HSSF CW, one fed with primary settled 22 wastewater (Settler line) and the other fed with the eff...
متن کاملBiotic wetland connectivity—supporting a new approach for wetland policy
Wetlands are key habitats connected physically and socially with processes occurring over a much wider territory. The biotic connection through dispersal mechanisms among wetlands is of primary importance to wetland management and policies. However, traditional wetland conservation approaches are based on the preservation of isolated sites considered to be of special importance (typically owing...
