Design Waterlogging Level Calculation based on Moisture Balance
Designed waterlogging level is one of the very important parameters in engineering design,which often determines the design elevation or flood prevention and drainage scheme of engineering design.At present,the most widely used calculation method is the historical addition method.The reliability of the result depends on the historical waterlogging high water level,but the conventional manual survey has many drawbacks.Based on the principle of moisture balance,this paper uses satellite image to calculate the historical waterlogging level,and puts forward the calculation method of water level decay velocity,so as to calculate the design waterlogging level.The calculation example shows that although there are certain requirements for satellite images,the results are scientific and reasonable,and have certain applicability.
