Motivation
· Modelling of river flows and coastal waves is a challenging
task due to complex bottom topography and moving free
boundaries. Here we aim to model the shallow water river
flows using space (SDG) and space-time (STDG) discontin-
uous Galerkin methods.

water level.
· These numerical methods combine some properties of
finite-element and finite-volume methods with several ad-
vantages [2]:
­ the structure of the scheme allows to use arbitrary de-
gree of polynomials per element,
­ the scheme is suitable for mesh adaptation,
­ the scheme is local since the discretization of an element
