| 摘 要： | 在统计四川省地震灾区106个县建国以来的山洪和泥石流灾害时间和相应的1 h和24 h雨量值基础上,得出四川省地震灾区山洪泥石流的临界雨量在不同的区域表现出不同的特征.其中1 h临界降雨变化于5～120mm,与山洪泥石流暴发关系最为密切;24 h临界降雨主要变化于35～235 mm,对山洪泥石流的暴发有极大的影响.在此基...

| Abstract: | Critical rainfall assessment is a very important tool for hazard management of torrents and debris flows in mountainous areas.The complexity of outbreak of torrents and debris flows is depended on critical rainfall.There is an urgent need to quantify the critical rainfall distribution in the area so that better hazard management could be planned and if real time rainfall forecast is available,and torrent and debris flow early-warning could be issued in advance.This study is based on 49-year observations(195... |
