Abstract This research proposes a method to calculate the steady solutions of exchange flow through various channel configurations. Two steady solutions, maximal and submaximal exchange flows, are satisfied for a pair of energy difference and exchange rate. For exchange flow over a sill, the reservoir depth is considered, in contrast to the literature which assumes infinite reservoir depth. The method discussed here can be applied even when the contraction and sill are not located in the same position, which has not been discussed in other literature. Furthermore, the influence of barotropic external forces on maximal exchange flow in channels with a combination of sill and contraction is discussed. The solution of the maximal exchange flow as a function of the external barotropic forcing can be used to calculate the average transport with a quasi-steady approach. The same method is then applied to calculate the maximal exchange flow solution and average transport in the Lombok Strait. The steady-state solutions discussed here are useful for understanding the hydraulics of two-layer flows and also as benchmarks for numerical schemes.
