Debris Flow Forecasting Method and System

Abstract

The invention discloses a system and a method for forecasting debris flow. The system comprises a hardware network monitoring system, a software network judging system and a forecasting system. The method comprises the steps of firstly, drilling and sampling for a debris flow monitoring scene; setting the hardware network monitoring system at the monitoring scene which meets debris flow occurrence conditions; recording the rainfall intensity and the rainfall quantity in a slope in real time and in the scene through a rain gauge; emitting signals through subsonic wave generators and electromagnetic wave generators in mesh holes when an object source moves; computing the displacement quantity after the software network judging system receives data transmitted from the debris flow monitoring scene through a remote communication means, and comparing the displacement quantity with an alarm threshold value by combining future rainfall information in weather forecast data; emitting forecast information by the forecasting system when the displacement quantity meets a forecast condition. According to the system and the method for scientifically forecasting the debris flow, provided by the invention, early-warning information can be emitted before the debris flow occurs by combining all data in the debris flow monitoring scene, evacuation time is competed for nearby people, and great loss is prevented from being caused.

Description

technical field [0001] The invention belongs to the technical field of mud-rock flow information monitoring and forecasting, and in particular relates to a method and a forecasting system capable of predicting mud-rock flow. Background technique [0002] Debris flows generally occur in mountainous areas or other areas with deep valleys and steep terrain. The main cause is flash floods caused by heavy rain or heavy rainfall. Debris and floods are mixed together to form a liquid-solid two-phase flow, and the solid matter is in a supersaturated state. Under the force of water flow and gravity, water, soil, sand, and stones are mixed and surged forward. After the formation of mud-rock flow disaster, its destructive force is great, silting up the river course, blocking the river, interrupting the traffic, destroying the farmland houses, and even destroying the town, causing huge losses. [0003] In order to prevent greater damage, a mudslide early warning system has been establi...

AI Technical Summary

Problems solved by technology

However, the existing early warning system can only issue warning information after the mudslide occurs, and the impact speed of the mudslide is extremely fast. After receiving the warning, local personnel often do not have enough time to respond urgently, so the early warning effect is usually not ideal

At present, there is still a lack of relevant systems and methods for effective forecasting of debris flow disasters before they occur
