Abstract
To investigate the cause of overflow in the torrential stream, the estimated peak flow of run-off and the maximum tarring capacity of the stream were measured at the upstream of Samsung-cheon located in Kwanak Aboretum during July, 1987. The results obtained from this study could be summarized as follows : 1. The surveyed catchment area was 477ha, which was 116 of the designed area (410ha) by the plan. 2. The maximum rainfall intensity measured was 99.5mm/hr and was almost same as the designed intensity(100mm/hr). 3. The surveyed run-off coefficient was 0.672 that was about twice as much as designed one(0.35). 4. The surveyed peak flow of run-off was
황발산지(荒發山地)에서 야계수로(野溪水路)의 월류발생원인(越流發生原因)을 구명(究明)하기 위하여 1987년(年) 7월(月)3일(日)부터 7월(月)23일(日)까지 삼성천(三聖川)의 상류지역(上流地域)인 서울대학교(大學校) 부속(附屬) 관악수목원(冠岳樹木園)의 야계수로(野溪水路)를 대상(對象)으로 예상최대홍수류량(豫想最大洪水流量) 및 수로최대유출량(水路最大流出量)을 조사(調査)한 결과(結果)는 다음과 같다. 1. 측정지점(測定地點)에서의 유역면적(流域面積)은 477ha로 설계유역면적(設計流域面積) 410ha의 116%였다. 2. 관측분석(觀測分析)된 최대강우강도(最大降雨强度)는 설계최대강우강도(設計最大降雨强度) 100mm/hr와 거의 같은 99.5mm/hr였다. 3. 실측(實測)한 유출계수(流出係數)는 0.672로 설계유출계수(設計流出係數) 0.35의 약 2배로 나타났다. 4. 예상최대홍수류량(豫想最大洪水流量)은 설계예상최대홍수류량(設計豫想最大洪水流量)
