　　报告简介： 

　　Connectivity is at the same time the result and the driver of many processes acting on natural and engineered systems.  Connectivity in geomorphic systems has been the subject of intense research in recent years tackling questions such as (1) what information about the bio-hydrogeomorphic processes can we learn from the emergent connectivity structures?  (2) Can those emergent patterns be understood in terms of fundamental principles? (3)  How does connectivity impact system dynamics, and particularly system response in the face of perturbations?   

　　In this presentation I will use river deltas as a case study to illustrate the potential of an integrated approach that relies on network theory, remote sensing and modelling tools to understand and predict the structure and dynamics of geomorphic systems. By studying river deltas through the lens of their channel networks, I will show how we can make significant strides toward solving the inverse problem of inferring process from form, establish a methodology to compare, contrast and classify river deltas, and understand and predict their dynamic response under different forcing scenarios. 

　　报告人简介： 

　　Alejandro Tejedor is a visiting scientist at the Max Planck Institute for the Physics of Complex Systems in Dresden, Germany.  Although, Alejandro earned a doctorate in Physics at University of Zaragoza (Spain),  his research is truly interdisciplinary with a particular focus at the intersection of Hydro-Geomorphology and Complex Systems science.  He has carried out most of his postdoctoral research in the USA, first at University of Nevada, Reno, and after that at University of Minnesota and University of California Irvine as a senior member in the group of Prof. Efi Foufoula-Georgiou.
