Online Platform: MS Teams (link to the video of the seminar)

About the Speaker: Rao S. Govindaraju is the Bowen Engineering Head and the Christopher B. and Susan S. Burke Professor in the School of Civil Engineering at Purdue University. He earned his PhD in civil engineering from the University of California, Davis, in 1989. His primary areas of research include surface and subsurface hydrology, contaminant transport, watershed hydrology, and climatic influences. He is interested in developing algorithms for analyzing and learning from hydrologic data. He specializes in problems dealing with uncertainty and spatial variability. His research work has been supported by various agencies such as NSF, EPA, DOD, and DOE.  He has chaired national level committees, served on the editorial boards of several journals, and served as the President of American Institute of Hydrology (2017-2018).

Abstract:  Hydrologic modeling efforts have to contend with several types of uncertainties. Measurement uncertainties exist because of errors in measurements of state variables, while structural uncertainties result from errors in the mathematical representation of hydrologic processes. Further, parametric uncertainties arise from both measurement and structural uncertainties, and because of limited information in the available data. Despite its ubiquitous nature, uncertainty quantification is not addressed often because of (i) lack of good algorithms, and (ii) inability to separate the various forms of uncertainty through calibration exercises. In this regard, Dr. Govindaraju will share some of his enduring research efforts that he has been pursuing in collaboration with students, and try to read the tea leaves as to where his future efforts will lead him in this journey.
