Moreover，a comparison of the types and scale of erosion and slope failure caused by the typhoon Nabi，in September 2005，and the above heavy rainfall event was also conducted within the study area. Characteristic results were as follows:   (1) The geological composition of the study area was shown to be of sandstone and shale base overlaid with pyroclastic fall and pyroclastic flow deposits originating from eruptions of Ata Volcano and Aira Volcano and volcanic ash and volcanic pumice originating from eruptions of Sakurajima Volcano. Two types of erosion and slope failure were observed as a result of the heavy rainfall event: failure of the sub-base and sub-grade-bearing body of the forest road itself as a result of groundwater between the bedrock and pyroclastic fall deposits combined with the influx of rain water，and a shallow landslide resulting from infiltration and concentration of rain water in the surface soil on the cutting slope.   (2) Areas of slope failure and sediment yield due to slope failure within the study area were also investigated. The area of slope failure ranged from 5 to 80㎡ (average: 31㎡) and the sediment yield due to slope failure from 5 to 336㎥ (average:49㎥). A larger area was affected and more sediment yield occurred with failure of the sub-base and sub-grade-bearing body compared with the shallow landslide.   (3) A greater number of slopes were damaged and more types of erosion and slope failure resulted from typhoon Nabi compared to the heavy rainfall event. Moreover，when erosion and slope failure were of the same type，the scale，especially the sediment yield due to slope failure caused by typhoon Nabi was much larger than with the heavy rainfall.","subitem_description_language":"en","subitem_description_type":"Other"},{"subitem_description":"2006年7月5日の豪雨に伴う鹿児島大学農学部附属高隈演習林の林道法面における侵食・斜面崩壊の実態を調査した。さらに，高隈演習林内の同じ地域を対象として調査した， 2005年9月の台風14号と2006年7月の豪雨に伴う林道法面の侵食・斜面崩壊の形態および規模についても比較した。得られた結果は以下の通りである。(1)調査地は砂岩・頁岩が基盤岩となりそれを阿多カルデラおよび姶良カルデラから噴出した降下火砕物や，桜島火山から噴出した火山灰・軽石が被覆した地質構造となっている。調査地でみられた侵食・斜面崩壊の形態として，基盤岩とその上部を覆う大隅降下軽石層の間に集中した雨水および地下水に起因して発生した路体を支持する路盤の決壊，ならびに切り取り斜面への雨水の浸透に起因した表層崩壊の2つが挙げられる。(2) 調査地において，斜面崩壊の面積および斜面崩壊による生産土砂量の測定を行った。その結果，斜面崩壊の面積は5～80㎡の範囲（平均31㎡)，斜面崩壊による生産土砂量は5～336㎥の範囲（平均49㎥) であった。路体を支持する路盤の決壊は，切り取り斜面における表層崩壊に比べ大きな規模を示した。(3) 同じ調査地で比較すると，2005年9月の台風14号に伴う林道法面の被害箇所数および林道法面における侵食・斜面崩壊の形態の数は，2006年7月の豪雨に伴うそれらよりはるかに多かった。さらに，同じ形態の侵食・斜面崩壊で比較すると，2005年9月の台風14号に伴う林道法面における侵食・斜面崩壊の規模特に斜面崩壊による生産土砂量は，2006年7月の豪雨に伴うそれに比べはるかに大きかった。","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima
