  • Patent number: 11874193
    Abstract: Provided is an ice avalanche-type glacial lake outburst surge generation and height measurement device. A glacial lake outburst test device includes a glacial lake simulation module and an ice avalanche surge module. An impact path, an impact angle, an impact scale, an impact velocity and a landslide density of an ice avalanche slider are controlled by simulation means. During formation of ice avalanche surges, the ice avalanche slider rushes into the glacial lake at a high speed, an ice avalanche pushes water to move in a sliding direction, thus forming a first surge, then continues to move to the bottom of the lake under the inertia and discharges a certain amount of water at its back. Movement of the landslide drives surrounding water to converge quickly into the back area, thus forming a second surge. Surge waves evolve around with a water entry point as a center.

  • Patent number: 11645900
    Abstract: The present disclosure relates to the field of early warning for geological disasters, and discloses an early warning method for icefall-caused moraine lake outburst disasters, which aims at solving the problems of low early warning precision and difficulty in implementation in an early warning solution of the prior art. The method includes: S1, calculating topographic parameters of moraine lakes and upstream glaciers thereof, and filtering a moraine lake to undertake focal monitoring; S2, calculating a freezing-thawing cycle index and a regional accumulated temperature index of an upstream glacier region for the moraine lake to undertake focal monitoring, S3, calculating a catastrophic climate determination factor TG-year, wherein if the catastrophic climate determination factor TG-year satisfies a corresponding catastrophic climate determination condition, an early warning condition is satisfied, otherwise the early warning condition is not satisfied; and S4, implementing early warning.
