A discharge monitoring system with velocity measurement by two H-ADCPs and numerical simulations using DIEX method was applied to flood-discharge monitoring in a compound channnel in Edogawa River under flooding due to typhoon no.1112. In the present system, we used two H-ADCPs in which one was installed in the main channel and the other in the floodplain. The results indicate that the calculated velocity and discharge using the present method with two H-ADCPs give good agreements with the field data measured by ADCP. The relative errors of calculated discharge by the present method using two H-ADCPs are appreciably lower than that using a H-ADCP. This fact demonstrates that the present method using two H-ADCPs are useful to monitor flood discharge in a compound channel.
