Agenda:
Presented by Kaveh Zamani, PhD, PE, PH

Basic Concepts

  • Error, mistake, uncertainty, and garbage in–garbage out:
  • Prelude and definitions
  • A bluffer’s brief guide to river modeling: What are the building blocks of a conventional “river model”?
  • Fundamentals of uncertainty analysis
  • Real world examples

Sources of Uncertainty and Low-Quality Results

  • Hydrology and meteorology and their hidden role
  • Uncertainties induced by roughness and infiltration
  • Uncertainties in grid and numerical solutions
  • How good is topography and bathymetry (Geometry)?
  • Hot start file
  • Physics of the problem: from geographic models to hydrologic models to hydraulic models and CFD
    • A hierarchy in complexity
  • Pre-processing and post-processing uncertainties
  • Other minor sources of error: errors in auxiliary solvers
  • Real world examples

Holistic View of River Modeling Purpose and Need

  • How good is good enough?
  • 1D, 2D, or 3D
  • AI, ML and statistical model, how far we can go?
  • Some common mistakes
  • Case studies

Speakers

Kaveh Zamani, PhD, PE, PH

Senior Stormwater Engineer at the California Department of Transportation

Dr. Zamani previously served as a Unit Chief at the California Department of Water Resources (DWR), Division of Flood Operations, where he led emergency flood response efforts as both Chief and Deputy Chief of Operations. Dr. Zamani has also worked with FEMA, multinational flood insurance firms, and in the private sector as a hydraulics and hydrology engineer, accumulating over 15 years of industry experience. Before entering public service and industry, he was a professor and research scientist at the Manly Hydraulics Laboratory in Sydney, Australia, and a Postdoctoral Fellow at UC San Diego. Dr. Zamani is a contributing member of the ASME V&V 20 Standard Committee on Verification and Validation in Computational Fluid Mechanics and Heat Transfer and has served on the ASCE Computational Hydraulics Committee since 2011. He has taught numerous undergraduate, graduate, and professional courses at UC Davis, McGill University, UNSW Sydney, Cal Poly, Cal State East Bay, and through ASCE. Dr. Zamani has also served as a subject matter expert in multiple legal cases involving flooding, sediment transport, scour, and river modeling.
