平床直堤间曲折复式河槽水流结构的研究是近年来的一个新课题，目前这方面的认识还在不断完善中。为探讨堤防线形对水流的影响，我们进行了两个不同弯曲相位的堤防与主槽间水流的实验。在第一种情况下，当堤防弯曲超前于主槽弯曲时，出现死水区，水流变窄。在第二种情况下，当堤的弯曲向后时，水流发生在整个河道中。
The flow structure of meandering compound channel between straight levees with fixed flat bed have studied recently and at present knowledge about that field is improving. To investigate the effect of levee alignment on the flow, we experimented two cases of flow which had different phase of meandering between levees and main-channel. In the first case, where the meandering of levee goes ahead of that of main-channel, dead water area appeared and the flow became narrow. In the second case, where the meandering of levee goes behind, flow occurred all over the channel.
