With the development of increasingly dense urban, urban drainage design plays an important role. Under design drainage causing floods, on the other hand, if it over designed it will reduce the efficiency of urban land. Seeing this phenomenon Dian Noorvy Khaerudin examine how is Time of Concentration (TC) affect rainwater discharge in the urban drainage area. In conclusion, this Civil Engineering Doctoral concentrations of water resources is found a model of Tc-Noor_UB that is Tc= 1,39’d2+ (1,02-90,08w-27,67S))K”d+0,89wS.
In the open examination [...]
