Methodology for the Calculation of the Runoff Coefficient with the Arrangement Tirado

For this research work, an adequate methodology was sought for the calculation of runoff coefficient with Tirado arrangement. To achieve this, first, variables that affect were identified, then model described arrangement, and as a third part coefficient, is proposed. From theory equation weighted coefficients expression Nadal manipulated, resulting in following relationship , considering arrangement Tirado. The tested different intensities, magnitudes correspond to 150, 200, 250 300 mm/hrs, 0.82, 0.87, 0.89, 0.91 respectively. This means that, higher intensity, will be higher, logically characteristics basin has variation space studied.
