Some general aspects of fluctuations of annual runoff in the upper Colorado River basin
The fluctuations of annual river flows and derived effective annual precipitations (defined as precipitation minus evapotranspiration on an area) of the Upper Colorado River Basin are subjects of this study. The data for this study are composed of annual flows for 14 river stations in the Upper Colorado River Basin and around it, and of the annual flows of the key station of the Upper Colorado River, at Lee Ferry, Arizona. Three statistical techniques were used: 1) distribution of the first serial correlation coefficient; 2) correlogram analysis; and 3) distribution of range. The series of annual ...
