And there can be one routing model at the last position for calculating "longitudinal outflow". Note that "inflow" and "outflow" here only refer to the location but not necessarily to water increases or decreases in the channel's water amount, as both might be positive or negative, depending on the selected submodel. If neither the upstream channel model defines a routing model for its last position nor the corresponding downstream channel model for its first position, both channels cannot become connected. If both channel models define routing models for the mentioned positions, it is unclear which is relevant. We suggest the following convention. Of course, add routing submodels that handle "external longitudinal inflow" (e.g. |sw1d_q_in|) at the first position and routing submodels that handle "external longitudinal outflow" (e.g. |sw1d_weir_out|) at the last position. Add routing submodels that handle "internal longitudinal flow" (e.g. |sw1d_lias|) at the last position for places with confluences or without tributaries. For branches, add them to the first position. """
