Title:
MS47
Advances in uncertainty quantification methods for hydrological applications • Part I
Type:
Subsurface models (cryoshpere, hydrosphere, lithosphere, pedoshpere)

Hydrological problems including groundwater flow and transport, storm surge, and tsunamis are often complicated by inevitable uncertainties in initial conditions, boundary conditions, and parameter fields. Large-scale simulations and ensemble-based methodologies for uncertainty quantification are now widely used in the analysis of such problems. These simulations are often computationally prohibitive due to high-dimensional parameter spaces and expensive forward models. New techniques for quantifying uncertainty in hydrological problems, especially in large-scale problems, are of utmost interest to the community. This minisymposium focuses on recent advances in uncertainty quantification methodologies and applications to problems in hydrology as well as presenting newer problems for which there is a need for practical uncertainty analysis.
