Consider the following statement regarding flood routing
P) Rainfall excess of equal duration are assumed to produce hydro-graphs with equivalent time bases regardless of the intensity of the rain
Q) Direct runoff ordinates for a storm of given duration are assumed inversely proportional to rainfall excess volumes.
R) The time distribution of direct runoff is assumed dependent of antecedent precipitation
S) The rainfall distribution is assumed to be the same for all storms of equal duration, both spatially and temporally
