13. SUPPLEMENTARY NOTES

14. ABSTRACTThis program will analyze monthly streamflows at a number of interrelated stations to determine their statistical

characteristics and will generate a sequence of hypothetical streamflows of any desired length having those characteristics.

The program will reconstitute missing streamflows on the basis of concurrent flows observed at other location and will

obtain maximum and minimum quantities for each month and for specified durations in the recorded, reconstituted andgenerated flows. HEC-4 will also use the generalized simulation model for generating monthly streamflows at ungaged

locations based on regional studies. There are many options for using the program for various related purposes, and the

program can be used for other variables such as rainfall, evaporation, and water requirements, alone or in combination.

15. SUBJECT TERMSmonthly streamflow, statistical analysis, hypothetical streamflows, durations, simulation, ungaged locations, standard

deviation, skew coefficient, Pearson Type III, normal, HEC-4
