Abstract:
Typhoon rainstorm can induce geological hazards such as landslides and debris flows and cause serious casualties consequently. Highresolution data a re essential for highresolution geological hazard prediction. Yueqing in Zhejia ng Province is selected as the studied area, which is frequently attacked by typh oons and is seriously influenced by geological hazards. Geological hazards induc ed by typhoon No.0414, No.0505 and No.0509 are taken as samples. Applicabilit y of radar rainfall estimation is assessed for the studied area. Relations betwe en typhoon rainstorms and geological hazard occurrences are carefully studied by use of radarraingauge rainfall estimation. The results show that the radar ra infall estimation can reflect the characteristics of triggering rainfall of geolo gical hazards in great details. Typhoon induced geological hazards need shorter rainfall duration, smaller effective rainfall, but higher critical rainfall inte nsity.
