【正文】 trong disorder destructive, defense is very difficult. And China39。 hilly steep slopes and deep valleys, elevation ups and downs, fast runoff . Because many rivers in Henan Province, a large gradient, therefore, the rapid convergence, flood fierce rally, easy to produce flash floods disasters. Flash floods from rainfall to the formation of generally a few hours or even less than an hour, more difficult to accurately forecast and control. 3 2, ferocious, destructive strength Since the end of steep mountain river, short process, flow speed, the impact of strong, destructive big, mining, transport and harm life and property are very serious. Its outstanding performance is a strong destructive causing serious casualties and infrastructure damage, recovery is very difficult, or even destructive. July 2021 Huai River in early heavy rains in the southern mountains, bamboo round rural North County mall war village, burst in the July 10 debris flow, flow rate m / s, a destroyed house, a family of three all died. 3, the seasonal high frequency Precipitation is induced by flash floods, landslides, mudslides main reason for higher rainfall year in geological disasters have significantly higher frequency. 4 September flood season, especially in the main flood season 6 to 8 months, is a mountain floodprone period. In the same basin, may occur even in the same year several flood disasters. According to statistics of Hunan Province, Hunan province flash flood disasters occurred in about 95% of flood disasters throughout the year, of which 6 to 8 month39。 Water reinforcement, flash floods and other disasters threaten Soil and Water Conservation District. Nonengineering measures include: meteorological, hydrological monitoring system, warning system and decision support system construction. The main research projects of nonengineering flood disasters prevention measures. 5 1, the establishment of meteorological and hydrological monitoring system According to sudden flash floods, regional characteristics, in a small basin, in the key areas of debris flow and landslides, increased rainfall and hydrological observation stations, automatic monitoring of key areas, rainfall warning station layout, realtime monitoring of rainfall, scattered residential areas can be Simple to install rain barrels manual observation, rainfall data collection, analysis of rainfall intensity on landslides, debris flow impact. 2, create a picture, video, multimedia monitoring system Because the visual image and video multimedia visibility, giving the effect of immersive, mudslides and landslides in key areas, add images, video multimedia monitoring project, usually transmitted by a certain time interval still pictures, start the camera when in the event of disaster function, realtime dynamic changes in transport during the scene of the disaster, flood control and disaster assessment to gather firsthand information. 3, the establishment of warning system Establish an accurate collection, transmission system and warning system, realtime collection of rainfall within the catchment, water level and flow of information, the establishment of multimodel hydrological, geological prediction system. Its main ponents include: data analysis, processing system。 torrential heavy rainfall disaster warning system。 when danger es, or the initial issuance of flash floods, monito
