东部阿尔卑斯山的地形、地质和水文条件决定着奥地利泥石流活动可能性的区域差异。松散固体物质(主要为高海拔地区的冰碛物)常常引起奥地利西部联邦各州的泥石流灾害。沿东南部阿尔卑斯山区降雨强度达世界记录(2小时30分降雨600—670mm)。沿北部和南部边界地区也常有日降雨量200—250mm的情形。泥石流沉积量达10万或100万m~3。泥石流冲积扇的地貌形态可表征流域的类型和受灾害冲击的程度。主沟地貌形态可用于计算泥石流的流速。
The topography, geology and hydrological conditions of the eastern Alps determine the regional differences in the possibilities of debris flow in Austria. Loose solids (mainly moraines at high altitudes) often cause debris flows in the states of the Western Commonwealth of Austria. Rainfall reaches the world record along the southeastern Alps (600-670 mm at 2 hours and 30 minutes). There are also daily rainfalls of 200-250 mm along the northern and southern border areas. Debris flow sedimentation volume of 100,000 or 1 million m ~ 3. The topography of the debris flow alluvial fan can characterize the type of basin and the degree of disaster impact. The main groove topography can be used to calculate the flow velocity of debris flow.
