The forest seemed apparently to die on the forest fire area in Honjima, Kagawa Prefecture, Japan. However, the soil that became growing basic of vegetation hardly suffered damage, and the forest recovery was started by the sprout, etc. in the next year. For restoration of forest fire area, the fascine mulching works and log barrier works using the damaged trees were used for the upper-stream, and chack dam and erosion control dam were set up in the downstream. Also, the forest restoration was tried with the plants and the microorganism that inhabit in Honjima to preserve a peculiar forest ecosystem.

The fire area need management to prevent enlargement of collapes and sinkage. and it need that repair Vegetation sack work, Soil arresting structure, Terrace-sodding works, Direct seeding works in greening works and Water cushion in erosion control dam. The whole of the Concrete stream grade stabilization structures were broken, it need to be repair. As pass the time, a lot of structures were abandoned. Therefore, it need to reorganize erosion control structures and the method of construction in the fire area

The purpose of this study is to acquire essential data to reduce the amount of woody debris resulted from the debris flow. This research examined topographic characteristics of the channelbed affecting generation, movement and storage of woody debris and woody characteristics related to number, sizes, shapes, decay, storage direction to mountainous stream. 1. The number of woody debris had a tendency to increase in proportion to stream width, but it was hardly affected by longitudinal gradient of stream. Especially, the greater amount of woody debris was stored at wide section of the stream with compound channel, and it was found in deposits of channelbed rather than in the present channel. 2. Total woody debris over 10㎝ in diameter and over 2m in length was 402 units and storage number was 35.3 units per 100m of stream. Average diameter of breast height and length were 14㎝ and 4m, respectively. The woody debris appeared shorter in length and greater in diameter at downstream than up-stream. 3. Since woody debris met sediments and bed-materials of great roughness in moving, the greater amount of woody debris without root was found in up-stream and down-stream, but deformed woody debris was discovered in upper stream. Decay of woody debris was more severe in downstream and woody debris on rotting process was found down-stream. 4. Storage direction of woody debris was mainly parallel to center line of stream, and rate of parallel and perpendicularity was 276 and 126 units, respectively. But, as woody debris storing to the perpendicular direction was unstable, the traveling debris could easily be stored. Therefore, some counterplan was required to prevent the traveling woody debris. 5. Tree species of woody debris was mainly larch, which occupied about two third of total woody debris(256 units). The woody debris of larch is easy to move due to hitting of channelbed materials or lower channelbed fluctuation because the lower part of larch is weaker than its upper part. Therefore, the section of the tree species planting in the riparian vegetation needs much more carefulness.

This study was carried out to investigate the export rate of suspended sediment by different precipitation intensity after forest road construction for torrential streams on three different watersheds with various forest road density(Watershed A : 6.67m/㏊, Watershed B : 5.52m/㏊, and Watershed C : control) in the Experimental Forest of Kangwon rational University. The results were as follows. 1. Closely related to the the amount of rainfall in both 1994 and 1995, the average streanfkiw rate was less than 0.25 × 10⁴㎥/day during May and June and 5.0 × 10⁴㎥/day during July and August. More than 25 × 10⁴㎥/day of streanflow rate was occurred twice in 1994 and seven times in 1995. 2. The amount of suspended sedimeant in three watersheds was less than standard of drinking water(25㎎/ℓ) before road construction with daily rainfall of 74㎜, 92㎜, and 120㎜ in 1994, also after road construction with daily rainfall of 21㎜ and 47㎜ in 1995. But, under the 192㎜ of daily rainfall, Watershed C did not show the difference in the amount of suspended sediment, however, Watershed A and B produced 1,525㎎/ℓand 775㎎/ℓ, respectively, which is 61 and 31 fold of stabdard of drinking water, and construction to export for 35 hours after rainfall. 3. The maximum amount of suspended sediment was less than the standard of drinking water with light rainfall before and after road construction. Under the 192㎜ of daily rainfall, the maximum amounts of suspended sediment in Watershed A and B were 13,150㎎/ℓ and 2,690㎎/ℓ, of 526 and 108 fold of standard of drinking water, respectively, showing obvious water pollution by sedimentation. Results of the study indicated that the forest road construction had great influence on the sedimentation, and getting increased by higher road density and heavier rainfall. Therefore such practices as vegetation covering and soil erosion control facility should be established accompanying with forest road construction to prevent from sedimentation.

최근의 砂防事業은 防災空間의 확보뿐 만 아니라 周邊環境에 잘 조화되고 生物資源이 풍부한 環境空問의 확보가 강조되고 있다. 일본에서도 이와같은 노력이 1990년대에 들어 활발히 진행되고 있으므로 우리나라의 사방사업의 참고가 될 수 있도록 일본의 親環境的 砂防事業에 대한 자료를 수집, 분석하였다. 구체적인 내용은 합리적인 水邊環境 造成과 親環境型 砂防事業이며, 親環境的인 砂防事業은 砂防댐, 流路工과 護岸工, 魚道 및 水質保全工 등에 대하여 정리하였다. In recent erosion control works, securing not only the disaster prevention space but the environmental space, harmonized with surrounding environment and abundant with biological resources are emphasized. Inspired of by the fact that efforts to secure such spaces have been being briskly promoted in Japan since the beginning of 1990s. we compile and analyze the Japanese sources about the 「environmentally-sound erosion control works」 to contribute to the erosion control works of our country. Specifically, in this report, we deal with the subjects of 「establishment of the comfortable river environment」 and 「environmentally-sound erosion control works」 which includes 「erosion control dam」, 「water channel works and revetments」, 「fish routes」 and 「water quality conservation works」.

제방 비탈면의 잡초관리는 상당한 노동력을 필요로 하기 때문에 풀베기 작업을 경감시키기 위해 일반적으로 잡초라고 불리고 있는 식물을 활용하여 「잡초로 잡초를 제어한다」라는 개념 하에 연구를 추진하고 있다. 제방 비탈면의 식생에는 ① 침식 및 붕괴방지, ②풀베기 작업시의 작업성 등과 같은 식물자체에 요구되는 조건, ③ 숲을 기본으로 한 농촌풍경의 향상·유지 및 ④ 걷기 편함 등이다. 황폐지나 제방 비탈면의 우점종인 식물에 대하여 이 4가지 조건에 맞추어 검토를 실시한 결과, Imperata cylindrica Beauv., Shibataea kumasaca Nakai, Sasaella kogasensis Nakai war. gracillima S. Suzuki 및 Hedera canariensis Willd.가 이용 가능할 것으로 판단되었다. Farm working also needs most of the labor on the weed management of the levee. Then, the research which controlled the weed in the weed was promoted in order to reduce this weed management. Required conditions for the levee vegetation from the viewpoint of the weed management are the following 4 points. ① the prevention of erosion and landslide. ② the improvement in the workbility at the mowing. ③ the improvement and maintenance of the rural landscape. ④ the accessibility. Next, the plants becoming dominant species in devastated land and slope of river banks were compared through these 4 conditions, and the utility was examined. As the result. Imperata cylindrica Beauv., Shibataea kumasaca Nakai, Sasaella kogasensis Nakai var. gracillima S. Suzuki and Hedera canariensis Willd. seemed to be usable. Finally, weed management method for connecting for the reduction in the mowing work using these plants was presented.
