“Based on CiteSpace analysis of 1726 literature from 2000 to 2023, "Direction 5 (training deep learning models to invert runoff based on long-term data series) has seen the most significant increase in publication volume, and since 2019, the publication volume has far exceeded other directions, becoming a hot research topic in the field of remote sensing inversion of runoff." This has opened up a new direction for the intelligent development of hydrological monitoring.”
