Title: Towards Better Projections of Extreme Precipitation Events under Climate Change

Abstract: To protect local communities against future flooding, design infrastructure for future plausible conditions and effectively operate our regulating water infrastructure, we need estimates of precipitation events under climate change. This is typically done by bias correcting the outputs of climate models that have coarse resolutions. However, the existing bias correction techniques often poorly project the high quantiles, which are of higher concern for flood risk mitigation and engineering design purposes. In this seminar, a statistical hybrid technique, called empirical quantile mapping with linear correction (EQM-LIN), is presented to improve the projection of future precipitation events under multiple plausible climate pathways around selected cities in the Southeast United States, with a history of flooding issues. The daily precipitation by one global climate model (GCM) was bias corrected using the EQM-LIN technique and a common statistical bias correction technique (EQM). Future precipitation time series under future climate scenarios-shared socioeconomic pathways (SSPs)-were then projected. It was found that the common statistical bias correction technique underestimates the high quantile events. The EQM-LIN, on the other hand, led to a better representation of these events. This study has implications for flood management, design of infrastructure and operation of regulating infrastructure like dams and gated spillways.

Speaker: Ebrahim Ahmadisharaf is currently an Assistant Professor in the Center for Resilient Infrastructure and Disaster Response Center (RIDER) and Department of Civil and Environmental Engineering at Florida State University. His work primarily focuses on predicting floods and surface water quality under a changing climate and land cover to support decisions related to civil infrastructure design, flood mitigation and water pollution control. Prior to joining Florida State University, he was a Hydrologic Scientist at Danish Hydraulic Institute (DHI) and a Postdoctoral Associate at Virginia Tech. He has a PhD in Civil and Environmental Engineering from Tennessee Technological University and both MSc and BSc in Civil Engineering from Sharif University of Technology. His research has been published in several peer-reviewed journals. Dr. Ahmadisharaf has delivered multiple presentations at State, national and international conferences. Since 2016, he has been a reviewer for various funding agencies (e.g., NSF, NASA, DOE, DoD and FFAR), peer-reviewed journals and an elected member of AGU Water Quality Technical Committee and ASCE-EWRI TMDL Analysis and Modeling Task Committee, and Surface Water Hydrology and Watershed Management Technical Committees. He has been also an Associate Editor of ASCE's Journal of Hydrologic Engineering since 2023. Dr. Ahmadisharaf's research has led to about $4 million of grants supported by Federal (NSF, NAS, EPA, USDA and NASA) and State (Florida Department of Environmental Protection) agencies as well as private foundations. In 2024, he was selected as the NASEM's Early Career Research Fellow.
