Abstract
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 potholes formed by glacial erosion and glacial moraine blocking the glacial troughs. 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 is accelerating, the number and volume of glacial lakes are increasing, and the risk of glacial lake outburst floods is also increasing.
[0003] Glacial lake outburst flood is a sudden natural disaster. Glacial lake outburst, also known as glacial lake flood, is a flood that occurs when the foreglacial lake originally surrounded by the ice dam pours out after the ice dam bursts. It is mainly caused by the erosion of the ice dam, which leads to the dam burst, or most of the adjacent glaciers 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 the safety of human life and property. Therefore, the prediction and simulation of glacial lake outburst floods 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.
