14. ABSTRACTThis report describes the application of
modified-puls for evaluating the relative accuracy of flood routing
methods to anatural river. The modified-puls method has at its core
the postulate that storage depends only on outflow rate. The
relationship S(0) is presumed known for the reach of interest
and for the range of outflow to be encountered. The hope that
the method will yield at least approximately correct outflow
hydrographs rests on the assumption that the storage
dependsprimarily, if not only, on outflow rate. If only certain
features of the outflow hydrograph, such as peak and time of peak,
are
desired with reasonable precision, then the dependence of S on 0
perhaps could be relaxed further, with dependence existing
only for some particularly important range of 0.
