SUMMARY:Hydrometeorological Challenges in Forecasting Streamflow
DESCRIPTION:\nProf. Witold F. Krajewski\nRose & Joseph Summers Chair in Water Resources Engineering\nThe University of Iowa\nMonday November 7, 2022, 2 PM ET\n \nAbstract:\nRecent technological innovations in computing, communication, sensors, and informatics stimulate\ndevelopment of new capabilities and challenges. In this talk, the author focuses on real-time riverine\nstreamflow and flood forecasting and discusses some old and new challenges and deficiencies in our\nscientific understanding of the key relevant aspects. To illustrate his points, he conceptualizes river flow\nas a continuum across scales from a single hillslope to a large river basin emphasizing rainfall to runoff\nconversion vs. flow routing. He examines the role of rainfall quantities vs. our observational and\npredictive modeling capabilities. Can we estimate (QPE) rainfall well enough? How well is well\nenough? What is the worth of rainfall forecasting (QPF) for skillful streamflow forecasting? Does it\ndepend on spatial and temporal scales? How? Another basic challenge is our inability to decompose the\npredictive uncertainty into that due to the inputs (e.g. rainfall and evapotranspiration) and that due to the\nrainfall-runoff model. The author also touches on the challenges presented by the proper use of data\nassimilation and artificial intelligence.\nBiosketch:\nDr. Witold F. Krajewski is the Rose & Joseph Summers Chair in Water Resources Engineering at the\nUniversity of Iowa. He also serves as Director of the Iowa Flood Center.\nDr. Krajewski’s scientific interests concern measuring, modeling, and forecasting precipitation using\nradar and satellite remote sensing. His current research focuses on understanding the genesis and\nevolution of floods through field data and modeling, and the quantification of uncertainty in hydrologic\nprediction at a range of temporal and spatial scales. Dr. Krajewski has published over 260 papers in\nrefereed journals on these topics.\nHe is a member of the National Academy of Engineering, American Academy of Arts and Sciences, and\na fellow of the American Geophysical Union and the American Meteorological Society. He has served\non numerous committees and panels of these and other professional organizations, and on the editorial\nboards of several journals. He was editor of Advances in Water Resources. In 2012, he was chair of the\nBoard of Directors of the Consortium of Universities for the Advancement of Hydrologic Science, Inc.\nWebinar:\nEvent site: https://go.umd.edu/krajewski ( https://go.umd.edu/krajewski )\nZoom Webinar: https://go.umd.edu/krajewskiwebinar ( https://go.umd.edu/krajewskiwebinar )\nZoom Meeting ID: 919 5532 3758\nZoom password: essic\nUS Toll: +13017158592\nGlobal call-in numbers: https://umd.zoom.us/u/aMElEpvNu ( https://umd.zoom.us/u/aMElEpvNu )\nFor IT assistance:\nCazzy Medley: cazzy@umd.edu\nResources:\nSeminar schedule & archive: https://go.umd.edu/essicseminar ( https://go.umd.edu/essicseminar )\nSeminar Google calendar: https://go.umd.edu/essicseminarcalendar ( https://go.umd.edu/essicseminarcalendar )\nSeminar recordings on Youtube: https://www.youtube.com/user/ESSICUMD ( https://www.youtube.com/user/ESSICUMD )\n
