【講座內(nèi)容簡介】

Hydrologic processes are affected by numerous factors, such as surface topography, climate, land covers, and soil types. The response of a hydrologic system to any natural and anthropogenic changes can vary significantly across micro-, meso-, and macro-scales. Can we really develop a model to quantify all processes and their dynamic interactions in such a complex system? It is surely a long journey with numerous uncertainties. This talk will focus on quantifying hydrotopographic dynamics across different scales and under varying climate conditions. The specific topics involve characterization of surface topography, evaluation of digital elevation models and their scaling effects, analysis of hydrologic connectivity and the associated threshold behaviors, and modeling of variability and hierarchy of hydrologic processes. This talk will also cover several new modeling approaches, including multi-scale modeling and joint simulation of subbasin-based and grid-based models. Particularly, research gaps, future opportunities, and potential challenges will be discussed.
