    32823282In the computations presented in this paper we use an explicit Euler
    32833283time stepping method with variable timestepping adapted to the
    3284 observed CFL condition.
    3285 
     3284observed CFL condition:
     3285
     3286\begin{equation}
     3287  \delta t = \min_{k,i=[0,1,2]}  r_k/v_i
     3288  \label{eq:CFL condition}
     3289\end{equation}
     3290where $r_k$ is the radius of the $k$th triangle and $v$ is the maximal velocity across the edge joining triangle $k$
     3291and it's neighbour triangle $i$ as calculated by the numerical flux function using the central upwind scheme of \cite{KurNP2001}.
