Abstract：

The lecture focused on the Generalized Unit Line Model created by Dr. Guo Junke and its application in watershed simulation. The model says that each watershed has three characteristic parameters, which are equivalent to the DNA of the watershed. As long as these three parameters are found from the previous data, given a heavy rainfall, we can analytically calculate the flood process line of the watershed using the generalized unit line model. In order to cultivate creative thinking, Professor Guo will highlight how the generalized unit line can be inspired by the COVID-19 curve, how it can be transformed from an empirical method into a rigorous analytical theory, how it can be validated with a large number of field and laboratory data, and how it can be applied to watershed design. Prof. Guo will also point out that the classical rationalization method, the time unit line method, and the SCS method are only a special case of the generalized unit line model. Finally, Prof. Guo will point out some applications of generalized unit line models in ocean, chemical, sports and other linear systems
