The big assumption in the forward Euler model is that $ S\\left(t\\right) $ is relatively constant during the timestep. This may not always be true. If $S\\left(t\\right)$ changes fast smaller timesteps need to be used to not make too big of an error. Other, more complicated methods to numerically solve differential equations exist such as Runga-Kutta. See the material of the MUDE course for more information on those. In hydrology it is always important to weigh if the error introduced by your numerical scheme is significant compared to the error introduced by the fact that the model is not perfect to begin with."
