Governing Equation

The depth-averaged 2-D continuity and momentum equations are given by

        ${\frac {\partial h}{\partial t}}+{\frac {\partial (hu_{j})}{\partial x_{j}}}=S$

        Failed to parse (unknown function "\eps"): {\displaystyle  \frac{\partial ( h u_i ) }{\partial t} + \frac{\partial (h u_i u_j )}{\partial x_j} - \eps_{ij3} f_c u_j h= g \frac{\partial ( \eta ) }{\partial x_j} + \frac{1}{\rho_0} \frac{\partial p_a }{\partial x_j} + \frac{\partial }{\partial x_j} \biggl[ K_{sa}  h \frac{\partial C_{sa} }{\partial x_j} \biggr \frac{\tau_i }{\rho} ] }

where $t$ is time, $U_{j}$ is the current velocity in the jth direction, $h$ is the total water depth, $C_{sa}$ is the salinity concentration, and $K_{sa}$ is the salinity mixing coefficient.
