Hi all I would like know if anybody has been concerned with the problem of the accumulation on an urban basin never, and more particularly, if he/she has stayed valued the possibility of an asymptotic course of the accumulation with increase of the dry time, or a course always increasing, or straight decreasing, having held in account also the casualties cause from the wind and from the traffic (for example); in each case I would like know if anybody (admitting an asymptotic course of the accumulation) he/she has conducted a study never for appraise what values of dry time go well to consider the basin to the his maximum state of accumulation. Thank you very much!!
