Course syllabus

Unstructured-grid (UG) technology has significantly matured during the last decade. Traditionally, UG models are applied to nearshore applications (rivers, estuaries, bays), but recent advance now allows their use in the deeper ocean (the so-called 'eddying regime'). We have presented some key requirements for this type of applications in Zhang et al. (2016).

The addition of eddying regime capability in our UG model (SCHISM) significantly expands its scope, and makes it possible to use a single UG model from very shallow (inundation regime) to very deep water, provided that appropriate numerical methods are used. The recent introduction of flexible gridding systems for the horizontal and vertical grids used in SCHISM (Zhang et al. 2015, 2016) enables model polymorphism that unifies different types of cells in a single UG grid: 1D, 2DV, 2DH, and full 3D, thus greatly enhancing the numerical flexibility and efficiency for truly cross-scale applications.

In this 3-day short course, I'll explain the fundamentals of the cross-scale SCHISM model, including the recent new developments on vegetation and ice dynamics. Hands-on tutorials will be conducted in some afternoons to familiarize the trainees with the basic tools useful for the modeling system. For trainees with prior UG model experience, I will highlight the key differences between SCHISM and other models for you to 'unlearn'. Upon completion the trainees will have acquired basic knowledge on workflow in typical SCHISM simulations.

We will start at 8:30am and finish around 5pm each day. A draft agenda is given below:

  1. Day 1: Introduction to SCHISM modeling system; physical formulation; numerical formulation
  2. Day 2
  3. Day 3:
