Task 6. Perform a Cyclic Analysis of the 3-day Precipitation Time Series
A cyclic analysis allows the user to create a set of pseudo time series that allow for easier investigation of data as well as inference of trends. Cyclic analyses can be performed within HEC-DSSVue using regular interval time series data (i.e. 1HOUR, 1DAY, 1MONTH, etc). Time series that are produced by a cyclic analysis include maximum, minimum, average, standard deviation, 5-, 10-, 25-, 50-, 75-, 90-, and 95-percentile.
Click Tools | HEC-DSSVue to launch HEC-DSSVue.
Within HEC-DSSVue, select the Detroit Dam 3-day duration precipitation time series.
Click Tools | Math Functions to open the Math Functions editor.
On the Statistics tab, change the Type to Cyclic Analysis.
Click Compute.
Within the Results window, select the data sets that you wish to save and then click the Save button that is near the middle of the editor, as shown in Figure 1.
Inspect the new time series that have been added to the list of available data sets.
Particularly interesting time series produced within the cyclic analysis are shown in Figure 2.
