Estimating the discharge capacity in straight compound channels

摘要

A method for predicting the stage-dis- charge relationship in astraight com- pound channel is presented. The approach is developedpsfrom an examination of the changes in the mean velocity of the mainchannel and the flood plain regions caused by the momentuminteraction between the regions. Experimental results from the UnitedKingdom flood channel facility Have been used to develop a methodWhich is capable of more accurately Representing the component meanveloci- Ties.
