Abstract

This paper deals exclusively with mathematical functions that link between time and the maximum annual flood height of Ocmulgee River in the U.S. state of Georgia during 60 years.

The best equations used this study were the cftool program including with the Matlab program. This program is based on the least square method using ready functions or suggesting any other functions. We looked at the data as a whole and found the best curve with the smallest errors. The second method was to look at the data horizontally. The differences between the years are 10 years, because there is a close approximation of these data. The results found that the error in the second method was much less than the error in the first method and the error did not exceed 1.6%.
