Abstract
This research has bken carried out for two years to develop the fundamental models and techniques
concerning the practical erosion control measures and rehabilitation policy. for the denuded
rocky forestland and eroding valley of Mt. Gwanak area in the capital region.
The main results obtained could be summarized as follows;
1. In planting with the selected seedling on denuded rocky forestland, it would be more effective
to introduce the "containerized seedling and planting practices" having the developed specifications
of each species. It is also required to introduce the fertilizing practices to rehabilitate
and accelkrate the deteriorated and dwarfed vegetation status in this area.
2. The denuded land of Mt. Gwanak area could be devided into 6 types as .described on the
conclusions. "Stone-debris catching' barrier structures on the slope" and "debris-and-water
holding trenchiwall structures" which have been developed as a new rehabilitating models
for the debris sliding sites are required for further study.
3. The most hazardous point where landslides occurred frequently is correspond to the upper
depressed area of end of the. first-order valley on the topographic map (I : 5000). It is, therefore,
needed to precede such the preventive protecting counter-measures as drains and retaining
walls at the corresponding points in "landslide hazard areas."
4. To stabilize the denuded torrential stream, such structural measures as debris dam, low-debris
dam, check dam, stream grade stabilization structures and revetment must be constructed in
connection with both upper and lower structures.
5. At the outlet of small hazardous valley where landslides occurr frequently, to raise the effect
of preventive erosion control it is essential to install the "sand-and-stone catching basin structures"
like Pokpogol and Hyeonggol of Gwacheon.
