Organic matter distribution of the root zone in a constructed subsuface flow wetland
Constructed wetlands are known widely by their characteristic properties like utilization of
natural processes, simple and easy of construction, operation and maintain as well. The constructed subsurface flow wetland is designed as a tank with an impervious boundary to prevent seepage and contain a suitable porous media in which emergent plants grow. The
water remains below the surface of the gravel/stone/rock media. Soil in constructed subsurface flow wetland absorbs and stores organic matter several years. This accumulation potentially leads to a decline of the filter ability of the constructed wetland.......
