Van Tuyl Lecture: Adrienne Marshall, CSM Geology and Geological Engineering

November 4, 2021 @ 4:00 pm - 5:00 pm

Adrienne Marshall, Colorado School of Mines Geology & Geological Engineering

Thursday, November 4, 2021, 4PM, BE 241/ Virtual

Topic: Hydrologic Modeling in Discontinuous Boreal Permafrost: Model Sensitivity and Uncertainty in Non-stationary Climates

Abstract: Process-based hydrologic models are the gold standard for simulating hydrologic conditions in future climates. These are particularly important in regions with complex interactions between climate, vegetation, and hydrology, such as the discontinuous boreal permafrost regions of interior Alaska. However, the projections of hydrologic models are subject to uncertainty stemming from input data, model structure, and parameter selection. Scientific research into the impacts of these sources of uncertainty is as old as the models themselves, yet much remains to be learned. Modern computational tools provide new opportunities to better understand and constrain uncertainty in hydrologic models. In this talk, we’ll discuss three questions that aim to address uncertainty in boreal hydrology: (1) How does parameter selection affect model suitability for non-stationary climates? (2) Which model parameters most affect the sensitivity of simulated hydrology to climate change? and (3) How does model structure – specifically the inclusion of projected vegetation change – impact projected changes in hydrology? The answers to these questions point towards important new research directions for hydrologists facing 21st century global change.
