“…To remove scale dependence from the streamflow metrics, monthly flows were expressed as a percent of mean annual runoff (Haines et al, 1988;Riggs and Harvey, 1990) and metrics describing flow magnitudes were normalized by catchment area. Data were standardized for use in the principal components analysis and cluster analysis to ensure each variable had equal weight.…”

“…The complicated dynamics of interception, infiltration, vegetative effects, and groundwater flow make such a supposition more difficult for real evaporation. Riggs and Harvey [1990] discuss the large differences between potential evaporation and real evaporation rates for disparate areas. Taking all this into account, it is presently not known whether the variations in mean annual temperature or those of relative humidity are a stronger control on evaporation in the Ottawa River basin.…”

“…Por ejemplo, el coeficiente de variación η de las descargas anuales del Río Brazos en Texas, que está ubicado en una zona semiárida de los Estados Unidos de Norteamerica, es de 0.66, mientras que η=0.37 para el Río Pascagoula en Mississippi, que está en una zona húmeda (Riggs y Harvey, 1990). Basado en en análisis de descargas anuales de 70 rí-os de zonas áridas y semiáridas de varias partes del mundo, McMahon (1979) encontró que η llega hasta 2.5 con un promedio de 0.99.…”

“…Los ríos en las zonas áridas y semiáridas de Norteamérica y Australia en general son menos periódicos que aquellos en zonas mediterráneas pero aún así tienen una periodicidad bien marcada. Sin embargo, ríos dentro de una misma zona climática, e incluso bastante cercano el uno al otro, pueden tener diferencias notables de periodicidad por otros efectos como son los geológicos y los topográficos (Riggs y Harvey, 1990). Un ejemplo, es la diferencia significativa de la variación mensual del porcentaje anual de caudales de los rí-os Cherry Creek y Bear Creek, ambos tributarios del South Plate cerca a Denver, Colorado.…”
