Title: Numerical simulation of rotational effects in geophysical flows.
------

Abstract:
---------
  
  In many applications in environmental and geophysical flows the time
  and space scales are mush larger than flows in industrial devices.
  In this case the dimensionless parameters are much larger and the
  Earth's rotation plays a significant role in these applications.
  In this talk we will present new numerical techniques to solve
  rotational effects in geophysics. The focus on a class of depth-
  averaged Navier-Stokes equations with hydrostatic pressure. As numerical
  tools we present a well-balanced finite volume method without Riemann
  solvers. A projection method is also discussed for the Coriolis force
  as well as reconstruction of numerical fluxes. Computational results
  are shown for several geophysical flows.
