Equilibrium Total load Transport model
Sediment Mass Balance Equation
The transport equation for the suspended load is given by
\begin{equation}\tag{1}
(1 - p'_m) \frac{\partial \zeta}{\partial t} = \frac{\partial q_{t*j}}{\partial x_j} + \frac{\partial }{\partial x_j} \biggl[ D_s |q_{t*}| \frac{\partial \zeta}{\partial x_j} \biggr]
\end{equation}
where is the sediment porosity, and is a bedslope coefficient.
