Both simulations on the downstream point TOTAL are broken down asper equations 1 and 3: RR(P INT , P E INT ) represents the runoff calculated by the rainfall-runoffcomponent applied on the INT intermediate area, ROUT ( ˆQ UP ) represents the routed calculatedupstream flow.This flow is calculated by the rainfall-runoff component applied on the UPsubcatchment. The sum of both contributions makes the simulation on TOTAL point.D R A F T July 24, 2008, 3:43pm D R A F T
