===Event Selection===
 
Once the relevant location specific data has been input, then the user should pick the events that they are interested in. The user can select from a number of pre-determined return periods or specify their own. All return period boundary conditions will be output in a single csv file for use as a TUFLOW boundary condition.

===Input GIS (optional)===
 
A GIS layer can be used to help specify an area when using point descriptors, or to specify a TUFLOW boundary to a particular region, point or line.

===Output===
Once the location, event selection and, if selected, the input GIS are specified, the user then selects the outputs that they are wanting to use within their TUFLOW model. These can be rainfall hyetographs or inflow hydrographs.
Rainfall outputs can be applied as 2d_rf or 2d_sa_rf TUFLOW boundaries. The user selects whether they want to use the Gross Design Rainfall, or the Net Design Rainfall where the ReFH2 losses have been applied. The former would usually be applied to TUFLOW with some allowance for losses within TUFLOW, most commonly via 2D Infiltration. The latter will have ReFH2 losses already accounted for so additional losses would not usually be required.
