Análise e desempenho de fórmulas de tempo de concentração na bacia do Ribeirão das Pedras, seção de estudo Tilli Center, no município de Campinas, S.P.

Abstract

The time of concentracion is one of the most input date in models runoff. That determination is particularly made by empirical equations, stablished by different localities and regions originally applied. The present paper evaluate the results of six formulas in comparison to collected data obtain from wathershed of Ribeirão das Pedras, Tilli Center study seccion/Campinas city/SP. The results showed the huge variability, however, is possible the use of time of concentracion formulas, since that choice represent the original characteristics.
