![]() From November to March, the main factor is the runoff in the preceding month, the contribution of which can be more than 85% from April to May, the runoff is significantly affected by snow, and its contribution in May is more than 65%. The results show that the factors influencing runoff in the upper Jinsha River are complex and have significant spatial and temporal heterogeneity. This paper uses relative importance analysis to analyze the causes of runoff changes from the perspectives of early runoff, rainfall, snowfall, evaporation and soil water content. The upper Jinsha River is an important ecological reserve and hydropower energy base in China.

Significant progress has been made in our understanding of ancient rainwater gathering and desert agriculture since the researchers in these fields began their initial work only a few decades ago. ![]() Stepwells are one of the many water-storing structures of ancient India that help us learn and understand hydraulics engineering in the course of human history. ![]()
