Debris flow prediction method

The prediction and prediction of debris flow is very important, which is an important step and measure for disaster prevention and mitigation. At present, China often adopts the following methods for the prediction and prediction of debris flow:

(1) Carry out fixed-point observation and research in a typical debris flow gully to try to solve the problem of formation and motion parameters of debris flow. For example, observation and research on Jiangjiagou, Daqiaogou and other debris flows in Xiaojiang River Basin, Dongchuan City, Yunnan Province; observation and research on the debris flows in Shahe River, Hanyuan County, Sichuan Province.

(2) Investigate the relevant parameters and characteristics of potential debris flow ditches.

(3) Strengthen the forecasting of hydrology and meteorology, especially the forecast of small-scale local heavy rain. Because torrential rain is the stimulus for the formation of debris flow.

(4) The establishment of debris flow technical files, especially the data on the elements, formation conditions, disaster conditions and remedial measures of large debris flow ditches should be recorded in detail one by one. And solve the problem of information reception and transmission.

(5) Divide the danger zone and potential danger zone of debris flow, or divide the debris flow disaster sensitivity zone.

(6) Carry out research on debris flow disaster prevention alarms and indoor debris flow model test research.
