Valley type ice lake storage capacity estimation method based on actually measured water depth

The invention relates to a valley type glacial lake storage capacity estimation method based on actually measured water depth, and solves the problem of low evaluation precision of glacial lake outburst geological disasters in the prior art. The method comprises the following steps: (1) interpreting the ice lake area by using multi-time-sequence remote sensing data; (2) estimating the water depth of the glacial lake according to the speculated water depth of the glacial lake and an empirical formula, estimating the average depth of the glacial lake according to the relationship between the average water depth and the area, and estimating according to the longitudinal section diagram of the main ditch of the debris flow gully of the glacial lake; (3) comprehensively measuring the water depth of the ice lake and the elevation of the lake bottom by using an unmanned ship sonar detection method; (4) completing lakebed elevation data, cross section measurement and water depth measurement of ice lake sections at di
