Abstract: A new theoretical 1D model of compound channels flows—the exchange discharge model—is presented. The interactions between main channel and floodplains are taken into account as a momentum transfer proportional to the product ...

Abstract: Experimental data are presented for flow in compound channels with symmetrically narrowing floodplains. In such a geometry, the flow behavior presents similarities with the more complex flow in a meandering compound channel, ...

Abstract: Flooding rivers usually present transition reaches where the floodplain width can significantly vary. The present study focuses on an abrupt floodplain contraction (mean angle 22°) in order to determine whether one-dimensional ...

Abstract: Common inlet design for compound-channel flumes does not ensure a proper upstream discharge distribution. As the total head in the upstream tank is the same for both main-channel and floodplain subsections, the velocity ...
