Clark time of concentration
Clark time of concentration
(OP)
Is the Clark Tc the same as the Tc from TR-55 ? Is it possible to calculate the Clark Tc using the TR-55 methodology (sheet + shallow conc. + channel) ?

What got me confused is this paper, http://prr.hec.gov.pk/Chapters/775S-3.pdf , it states:
"The definition of time of concentration in Clark model is somewhat different than that used elsewhere in hydrology. Clark’s Tc is time of travel required by last drop of rainfall excess at the hydraulically most remote point in the catchment to reach the channel network, in contrast to the outlet that is used elsewhere (Straub et al., 2000)."

RE: Clark time of concentration
We're working in Jordan on a sub-basin that drains into the dead sea. The catchment lies in a semi-arid to arid region and our objective is to build small desert dams to address the water deficiency issue in the country. The last study on the sub-basin was done in the early 1990's and mainly used SCS methodologies. Time has shown that the results are unsatisfactory, mainly because the SCS methods were developed for humid regions; very different from what we have here. The Clark method will be more suitable for our region given its flexibility.
