Watershed Erosion Processes

lt;p>Tongxin Zhu is a Professor of Geography and Environment at University of Minnesota Duluth. He received his Ph.D. at the University of Toronto in 1998, and has published 5 papers in books and more than 40 papers in referred journals. His research interests focus on the geomorphic and hydrologic processes at plot, hillslope and watershed scales by integrating field and experimental studies with simulation modeling. His recent research includes assessing the susceptibility and erosion risk of mass movement, investigating the spatial variability of soil shear strength within the gully systems, and examining the interactions of water erosion, mass movement, tunnel formation and gully development at watershed scale. He teaches classes in physical geography, environment, and Geographic Information Systems (GIS).

Xiangzhou Xu is a full professor and Ph.D. supervisor at Dalian University of Technology (China). His research focuses on soil conservation and sustainable development. The Topography Meter developed by him opened a new way for tracking and measuring landslides. He is the principal investigator of over ten national, ministerial and provincial projects. He has also won two prizes of the Ministerial and Provincial-Level Science and Technology Awards as the first or third accomplisher. He is the first or corresponding author of over 50 journal articles, and first or co-author of three monographs. Two United States Patent and 20 Chinese invention patents filed by him has been granted.
