Las CD se estiman por medio del análisis de frecuencia (AF), método estadístico que ignora las incertidumbres hidrológicas involucradas. Cuando tales indecisiones son tomadas en cuenta, las CD no son magnitudes únicas, sino una gama de valores, y entonces, el diseño y la revisión de la infraestructura hidráulica se vuelve un proceso indeterminado. La corrección de las CD conforme a la incertidumbre hidrológica se puede realizar de forma práctica y simple, con base en el procedimiento que han desarrollado Botto, Ganora, Claps y Laio (2017), fundamentado en un factor de corrección (   y &#94;), que modifica las CD obtenidas con el AF. El valor de    y &#94; resulta de varias ecuaciones empíricas, función de tamaño del registro disponible de gastos máximos anuales y del periodo de retorno (Tr) en años o inverso de la probabilidad de excedencia. Se dispone de cinco ecuaciones de    y &#94;, una para cada función de distribución de probabilidades (FDP) más utilizada en el AF, éstas son: Log-Pearson tipo III, general de valores extremos, logística generalizada, Log-Normal y Pearson tipo III. El método correctivo se aplicó a siete registros de crecientes, previa selección objetiva de la FDP más adecuada, según sus cocientes de momentos L. Se obtuvo que los factores correctivos (   y &#94;) varían en el Tr de 50 años del 1 al 5.6%; en cambio, en el Tr de 1 000 años, las correcciones fluctuaron del 14.9 hasta el 43.9%.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract The planning, design and/or hydrological inspection of hydraulic works is based on what are called Design Floods (DF) or maximum river flows associated with low probabilities of exceedance. DFs are estimated using Frequency Analysis (FA), a statistical method that ignores the hydrological uncertainties involved. When such indecisions are taken into account, DFs are not unique magnitudes but a range of values, and therefore, the design and inspection of hydraulic infrastructure becomes an indeterminate process. DFs can be corrected, according to hydrological uncertainty, using a simple practical procedure developed by Botto, Ganora, Claps and Laio (2017). The method is based on a correction factor (   y &#94;), which modifies the DFs obtained with FA. The value of    y &#94; is obtained with several empirical equations that are a function of the size of the available records of annual maximum flows and of the return period in years or the inverse of the exceedance probability. There are five equations of    y &#94;, one for each of the most used probability distribution functions (PDF) in the FA, these are: Log-Pearson type III, General of Extreme Values, Generalized Logistic, Log-Normal and Pearson type III. The corrective method was applied to seven flood registers, after objective selection of the most appropriate PDF, according to their L moment ratios. We obtained that the corrective factors (   y &#94;) vary in the 50-year Tr from 1% to 5.6%, while in the 1000-year Tr corrections fluctuated between 14.9% and 43.9%.]]></p></abstract>
