### Introduction to Flood Frequency Analysis

Jan 13 2017 · As shown in the figure above river discharge (flow in m 3 /s or ft 3 /s) is generally plotted on the y-axis using either a linear or logarithmic scale. Return period and/or exceedance probability are plotted on the x-axis. In the figure below the x-axis scale is a modified probability scale so that the resulting flood frequency curve appears as a straight line.

Consequently proper analysis requires more sophisticated statistical techniques. A normal distribution can be fully characterized with two parameters mean and standard deviation. A more generic method of describing distributions is through the Weibull function. A Weibull distribution can also usually be characterized by two parameters.
