 r7135 In general, for multiples of the minimal depth $N H_0$ one obtains $\left[ \frac{\mu}{h + h_0/h} \right]_{h = N H_0} = \frac{\mu}{H_0 (1 + 1/N^2)}$ \frac{\mu}{N H_0 + H_0/N} = \frac{\mu}{h (1 + 1/N^2)} \label{eq:flux limit multiple} which converges quadratically to the true value with the multiple N. Although this equation can be used for any depth, we have restricted its use to depths less than $10 * H_0$ (or 1 cm) to computational resources. According to Equation \ref{eq:flux limit multiple} this cutoff affects the calculated velocity by less than 1 \%. %The developed numerical model has been applied to several test cases
