Abstract

PURPOSE:To send out an alarm for taking refuge to residents by predicting the occurrence of debris flow disaster by automatically referring to measured values of rainfall in a limited area during heavy raining period and a danger-safety boundary line previously set up from the geographical and soil features of the area for comparison. CONSTITUTION:Judging from the geographical and soil features of an area where debris flow disaster could occur, a precaution curve line (y=b1/x+a1), a warning curve line (y=b2/x+a2), and a danger-safety boundary line, which are peculiar to each area, are set up in advance. When electric pulse sent out each time unit rainfall is measured from a rain guage 1 and calculated values of rainfall intensity (x in mm./time) and accumulated rainfall (y in mm.) from time information of a timer 3, which are calculated by an arithmetic unit 2, reach the warning curve line, an alarm information is sent out and an attention or warning preliminary alert is sent out by an alarm device 41, e.g., siren, etc., to the residents of the area.
