5results about How to "Realize self-regulation" patented technology

This invention discloses a method for simulating the underwater topography of natural lakes based on shoreline topographic features, belonging to the field of earth science technology. This invention focuses on "simulating the natural process of lake level drop," fully utilizing the lakeside topographic information and morphological parameters extracted from DEM data to achieve reliable estimation of water depth and water storage in natural lakes without actual measured data. The main advantages are as follows: 1) This method can automatically adjust the calculation formula for underwater topography based on lake morphological parameters, thereby achieving autonomous adjustment for water depth prediction of different types of lakes, effectively improving the accuracy and reliability of the simulation results; 2) In the underwater topography simulation process, the reshaping effect of lake sediments on the underwater topography is considered, and a correction formula is introduced into the slope calculation module, making the slope calculation results closer to the actual lakebed morphology, further improving the accuracy of the simulation process.
