	Once the bc_base has been set up then a '''.tef''' file can be generated which populates the ARI variable above with the relevant ARI for the specific question. The '''TEF''' file also creates ~~anew~~ new output folder for each return period.

	Originally published in 1999, and subject to continuous development, the Flood Estimation Handbook (FEH) comprises the standard methods for estimating flood frequency. The rainfall-runoff model is one of two core handbook methods. In 2015, the Centre of Ecology and Hydrology (CEH) and Wallingford Hydro Solutions (~~http~~://www.hydrosolutions.co.uk) released a new version of the Revitalised Flood Hydrograph rainfall-runoff model (ReFH2) which allows users to generate design flows and hydrographs from given rainfall events for both catchment and development sites. ReFH2 is a rainfall-runoff model specifically applicable to the UK. It takes inputs from the FEH2013 web service (https://fehweb.ceh.ac.uk), and generates design rainfall events and provides a method for calculating design runoff from sites or contributing subcatchments.

	This post provides instructions of how to obtain direct rainfall and inflow inputs from the ReFH2 software for use within a TUFLOW model. This requires the input of data from the FEH Web Service and the selection of the appropriate return period/duration combinations of which the user is interested. This outputs the time-varying rainfall and total runoff (as well as runoff contributions) which can be exported for use within TUFLOW. It is also possible to use TUFLOW event files to increase efficiency when creating models for multiple return period/duration combinations. A ReFH2 to TUFLOW tool is available for the QGIS TUFLOW Viewer plugin, more details can be found on the [QGIS_ReFH2_to_TUFLOW \| QGIS ReFH2 to TUFLOW] page.
