===Climate Change===
Climate change options can be added by clicking on '''Edit''' under the climate change section. This opens up a table widget that the user can then add/remove climate change scenarios based on the guidance in ARR v4.2. Scenarios added in the table will be displayed in the climate change section (underneath the edit button). Note: each scenario name must be unique and generally the table widget will force unique names. The scenario names will be used throughout the outputs and the user is free to customise the scenario names as they want.<br>
Climate change options can be added by checking on a combination of climate change years and Representative Concentration Pathways (RCP) in the dialog. Selecting at least one climate change scenario will output:
 
The table columns within the table widget are based on ARR guidelines v4.2 and the examples presented in Book 1, Chapter 6. Please note the following assumptions:<br>
* Near-term horizon = 2030
* Medium-term horizon = 2050
* Long-term horizon = 2090
* Temperature Change - Setting this to -1 will adopt the temperature changes output in the climate change part of the ARR datahub download. If a value or zero or greater is set by the user, this will be adopted instead of the datahub values and it will be assumed that these are changes relative to the pre-industrial period. Note: the temperature change will be stopped from going negative within the calculation.
 
 
By adding climate change scenarios, the following outputs will be turned on:
* An extra boundary database file: '''bc_dbase_CC.csv'''
* Climate change inflows will be appended to the end of each event's inflow file
* One additional event option will also be added to the event file for each combination of selected climate change scenarios labelled asbased CC01,on CC02,the CC03,...scenario etc.name. It is intended that the climate change scenarios would be treated as a separate event (e1 = magnitude, e2 = duration, e3 = temporal pattern, e4 = climate change scenario) however the output files can easily be manipulated by the user to configure the model differently.<br><br>
* The following CSV files will be written to the '''data''' output folder:
** ''<scen_name>_rainfall_factors.csv''
** ''<scen_name>_rainfall_depths.csv''
** ''<scen_name>_losses.csv''<br><br>
