  • The 2-D analytical solution for tran sverse velocity distribution in compound open channels was presented based on the Shiono and Knight method, in which the secondary flow coefficient was introduced to take account in to the effect of the secondary flow. The modeling results agree well with the expermiental results from science and engineering research council-flood channel facility (SERC-FCF), based on which the effect of geography on the secondary flow coefficient is analyzed, as well as the essential reason for such effects. The modeling results show that the in tensity of the secondary flow is related with the geometry of the compound channel section, and the sign of Kvalue is related with the rotating direction of the secondary flow cell, which proposes scien tific reference for the selecting of Kvalue.
