CLCULOS

PARA PRECIPITACIONES MAXIMAS ANUALES EN 24 HORAS

PARA PRECIPITACIONES MAXIMAS MENSUALES EN 24 HORAS

En este caso trabajaremos con las anualesA) ANALISIS DE DISTRIBUCIONI. ANALISIS CON DISTRIBUCION NORMAL

II. ANALISIS LOG. NORMAL 2 PARAMETROS

Donde Pexc. = 1/Tr

III. ANALISIS LOG NORMAL 3 PARAMETROS

AS: AsimetriaSi As < 0 Indica que existe presencia de la minora de datos en la parte izquierda de la media, aunque en algunos casos no necesariamente indicar que la distribucin sea asimtrica negativaSi As = 0 la distribucin ser simtricaSi As > 0 Indica que existe presencia de la minora de datos en la parte derecha de la media, aunque en algunos casos no necesariamente indicar que la distribucin sea asimtrica positiva

IV. ANALISIS POR METODO GUMBEL

P exc = F (x > X)

B) PRUEBAS DE BONDAD DE AJUSTE SMIRNOV-KOLMOGOROV

C) INTENSIDAD DE PRECIPITACIONESCon los datos ajustados hacemos:

El tiempo de concentracin = 1.63 horas

Graficamos nuestra curva IDF

CALCULO DEL CAUDALPara esto se tendr en cuenta la frmula:Q= CIA/360C: coeficiente de escorrenta I: Intensidad para un determinado tiempo de retorno de acuerdo a un tiempo de concentracin.A: rea de la cuenca en Has

-Precipitacin mxima corregida sobre la cuenca (P):
