Description

Technical Field

[0001] The present invention relates to the field of geological simulation technology, and in particular to an intelligent glacial lake outburst simulation system. Background Art

[0002] Glacial lakes, also often called glacial lakes, are lakes formed by the accumulation of water in glacial troughs blocked by potholes eroded by glaciers and moraines. Glacial lakes are mainly distributed in the process of high mountain glaciers, among which the Nyainqentanglha Mountains and the Himalayas are more common. They are generally distributed at higher altitudes. With the intensification of global climate change, the melting rate of glaciers has accelerated, the number and volume of glacial lakes have continued to increase, and the risk of glacial lake outburst floods has also increased accordingly.

[0003] A glacial lake outburst flood (GLOBF) is a sudden natural disaster. A GLOBAL LAKE OUTBREAK FLOOD (GLOBAL LAKE FLOODS) is a flood that occurs when an ice dam bursts and a foreglacial lake originally surrounded by the ice dam pours out. This is mainly caused by ice dam erosion, which leads to dam collapse, or large parts of the adjacent glacier collapse into the foreglacial lake, causing huge fluctuations in the water body in the foreglacial lake and triggering floods. Its occurrence may cause serious flood disasters in downstream areas and threaten human life and property safety. Therefore, the prediction and simulation of GLOBAL LAKE OUTBREAK FLOOD is of great practical significance.

[0004] At present, simulation research on glacial lake outburst mainly focuses on two aspects: numerical simulation and physical model experiments. Although numerical simulation methods can simulate the entire process of glacial lake outburst, they are limited by computing resources and often cannot achieve sufficient accuracy and resolution. Although physical model experiments can intuitively display the process of glacial lake outburst, they are limited by experimental conditions and often cannot simulate the glacial lake outburst process under real conditions. They cannot accurately reflect the evolution process of glacial lake outburst floods, and the prediction of the evolution process and impact range of glacial lake outburst floods is still not accurate enough.
