HORIZONTAL SUBSURFACE FLOW CONSTRUCTED WETLAND

CONCLUSIONS
In the experimental pots replicating VF constructed wetlands, a variety of forage rice (" Kusahonami ") was cultivated using river water under various supply rates (0.1, 0.2, and 0.6 m 3 /(m 2 ·day)) for 169 days. As a result, the growth of the rice increased with the[r]

Wetland water storage is determined by the inflows and outflows together with the characteristics of the wetland basin. Depth and storage in natural wetlands are likely to be modulated by landscape features, such as the depth of a[r]

Effluent discharges from municipal, industrial, and agricultural activities constitute major sources of pollution on land and water bodies. During the 1990s, large -scale application of Constructed Wetlands (CWs) as a remediation option drew much attention globally from the public and green groups a[r]

(Gillespie et al., 2000; Mays and Edwards, 2001). There have been few studies on the removal of heavy metals from wastewaters containing low concentrations of these metals, such as domestic wastewater, by constructed wetland systems.

Deep zones in surface flow constructed wetlands are sup- posed to serve several purposes (Knight and Iverson, 1990).
These deeper areas extend below the bottom of the vegetated basin areas by at least 1 m to exclude the development of rooted macrophytes (Figures 18.9 and 18.10 ).[r]

Soil conditions can also constrain wetland restoration efforts. Soils provide multiple services for the plants and animals being restored, i.e., soils conduct groundwater, trans[r]
