 SCHISM is a derivative work from the original  [http://www.stccmop.org/knowledge_transfer/software/selfe SELFE] model (v3.1dc as of Dec. 13 , 2014).  SCHISM has been implemented by Dr. Joseph Zhang (College of William & Mary) and other developers around the world. SELFE was developed at the Oregon Health Sciences University.
-SCHISM (Semi-implicit Cross-scale Hydroscience Integrated System Model) is an open-source community-supported modelling system based on unstructured grids, designed for the effective simulation of 3D baroclinic circulation across creek-river-shelf-ocean scales. It uses a highly efficient semi-implicit finite-element Eulerian-Lagrangian algorithm to solve the Navier-Stokes equations (in either hydrostatic and non-hydrostatic form), in order to addresses a wide range of physical and biological processes. The numerical algorithm is high-order, and stable and computationally efficient.  Although not guaranteed in the numerical scheme, the volume conservation is good. It also naturally incorporates wetting and drying of tidal flats.

It also naturally incorporates wetting and drying of tidal flats.
 Although the SELFE model (from which SCHISM was derived) was originally developed to meet specific modeling challenges for the Columbia River, it has been extensively tested against standard ocean/coastal benchmarks and applied to a number of bays/estuaries around the world, in the context of general circulation, tsunami and storm-surge inundation, water quality, oil spill, sediment transport, coastal ecology, and wave-current interaction. SCHISM includes many improvements of the original SELFE code (v3.1dc); see recent [http://ccrm.vims.edu/schism/schism_pubs.html publications] for more info.
