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