The present invention relates to a physical catchment model for a rainfall runoff experiment, characterized by being a physical catchment construction model having a structure in which a real terrain miniature is disposed at one side thereof and a developed terrain miniature is disposed at the adjacent other side thereof. According to the present invention, the rainfall runoff experiment is performed by collecting rainwater flowing out downwardly from the terrain miniatures through the application of artificial rainfall to the physical catchment model for the rainfall runoff experiment so as to easily compare and measure a change in the amount of rainwater flowing out for a predetermined time during rainfall in an undeveloped real terrain and a developed terrain, thereby enabling easy establishment of a national land use and development plan in the development planning stage for utilization of national land so that natural disasters caused by the rainfall runoff of land planned to be developed can be prevented in advance.

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.
