Data A4 Hydrological Data during Recent Major Floods Table DA4-1 Comparison of Peak Discharges of Major Floods Bold : Seems to be more reliable values (Note : These indicate maximum peak discharge of a series of floods. Hence, time differences among stations in the table does not indicate propagation of one peak.) C.
