Abstract
Wetlandsis developing on the lava plateau in Eundae-ri, even though there are no majorstreams into this area. As a result of drilling, 1~2m clay layer is founded under the superficial formations of the wetland, which are the main reasons for formation of the wetlands by limiting vertical drainage. The clay layer's Granulometry/XRD show very different characteristics from in situ weathering of basalt, and since 2~3cm of sand layer exist within the profile, the clay layer seems to be supplied and deposited from outside through surface/sheet flows. To keep the wetlands sustainably, the supply of water into the wetlands has to be increased by restoring the surface/sheet flow which is limited or deformed by pavement road.
