ARR Temporal Rainfall Patterns
From the Data Hub associated with Australian Rainfall and Runoff, it is possible to save a .zip file containing rainfall patterns appropriate to the site of interest.
This file contains two comma separated variable (.csv) files. The one named 'Increments.csv' contains the temporal patterns, expressed as percentages:
This contains a number of patterns in ensembles or sets of 10 values - 10 alternative storms. They are drawn from pluviometer data for various regions of Australia and representing frequent (AEP > 14.4%), intermediate (between 14.4 and 3.2% AEP) and rare storms (< 3.2% AEP).
The regions are shown in Figure 2.5.7 in Chapter 5 of Book 2 of ARR. Although the process of obtaining patterns is based on a longitude and latitude, there are only 12 zones.
The other .csv file in the downloaded zip file contains more details of the selected storms.
The 'Increments.csv' file can be inserted into DRAINS as part of the process for adding ARR storms.
