SYSTEMATIC VARIATION PATTERN OF ANNUAL RIVER FLOWS

STATISTICAL ANALYSIS OF ANNUAL RIVER FLOWS IN THE UNITED STATES, SOME EUROPEAN COUNTRIES AND SOUTHERN AUSTRALIA, IN LATITUDES HIGHER THAN 34 DEGREES N OR S INDICATES A USEFUL SIGNIFICANT RELATIONSHIP BETWEEN THE STANDARD DEVIATION OF THE LOGARITHMS OF INCHES DEPTH OF ANNUAL RUNOFF FROM A RIVER CATCHMENT AND THE GEOMETRIC MEAN ANNUAL RUNOFF DEPTH. FOR THE SEPARATE ZONES, EQUATIONS AND TABLES ARE GIVEN FOR THE EVALUATION OF PROBABILITIES OF ANNUAL FLOW OF A RIVER FROM ITS ESTIMATED GEOMETRIC MEAN DEPTH OF ANNUAL RUNOFF AND THESE CAN BE USED WHERE RECORDS ARE INADEQUATE OR AS A CHECK ON OTHER METHODS. THE LOGARITHMIC DISTRIBUTION WAS FOUND TO BE APPROPRIATE FOR STATISTICAL ANALYSIS, WITH A GENERAL TREND TOWARDS SLIGHT NEGATIVE SKEWNESS. TESTS OF A SMALL SAMPLE SUGGEST THAT DRY SEASON FLOWS MAY FOLLOW A SIMILAR PATTERN TO THAT OF THE ANNUAL FLOWS. /ASCE/
