抄録

To examine the temporal variation in the amount of roof deposit, which is one of the main non-point sources in urban areas, and its association with dry fallout, a continuous monitoring of roof-deposit environments is performed by a modeled-stormwater sampling (MOS) technique, by which one can easily obtain deposits from a model roof under simulated rainy conditions. The results indicate that the amount of sediment on the roof ( SS_roof ) decreases rapidly just after a rainfall and then increases gradually until the next rainfall occurs. The temporal variation in SS_roof  is similar to that in the accumulated value of the deposition rate of SPM (suspended particulate matter), ∫D_SPM dt. The correlation coefficient between SS_roof  and ∫D_SPM dt is 0.839, showing that the mutual relationship between them is sufficiently estimated. Note that to obtain an accurate evaluation of roof-deposit load, it is necessary to use ∫D_SPM dt, in which the influences of antecedent fine weather conditions and dry fallout are explicitly incorporated.
