A method for optimizing the location of rain gauges based on rainfall analysis

This invention relates to the field of rainfall measurement technology, and particularly to a method for optimizing rain gauge location based on rainfall analysis. The invention divides all rain gauges into several rainfall sub-regions based on whether rainfall occurred at all stations during the same time period, and whether it was light or heavy rain. Rain gauges within each sub-region share strong rainfall commonalities. For rain gauges with the same rainfall commonalities, a neural network model is used to fit the rules between coordinate changes and rainfall changes. This neural network model can calculate rainfall in areas where no rain gauges are located. Then, using the arithmetic progression of rainfall from adjacent rain gauges as the optimization objective, a particle swarm optimization algorithm is used to adjust the location of rain gauges within each region. Because the adjustment is based on the existing conditions, it ensures reasonable rain gauge distribution and coverage while capturing as much varied rainfall as possible, significantly improving the accuracy of rainfall measurement within the region.
