Usually carried out by a Responsible Authority The guidance in this section is targeted at Responsible Authorities. Key points for Responsible Authorities are given in green boxes. Scoping (Chapter 3) Data Collection SoR Commissioning a study (Chapter 4) Usually carried out by a contractor These sections should be read by Responsible Authorities and contractors. The discussion in these sections aims to give Responsible Authorities sufficient background to critically assess contractor modelling. Key points for contractors to ensure a consistent approach, and quality of flood modelling in Scotland are given in red boxes.

The guidance covers fluvial, pluvial and coastal flood studies. Fluvial and coastal studies are covered in detail; however, for pluvial studies where a detailed representation of the surface water drainage network is required, Scottish Water and CIWEM Urban Drainage Group 2 (UDG) guidance for modelling sewer systems should be followed.
For studies covering combined pluvial and fluvial flooding or combined pluvial and coastal flooding this guidance should be used for the fluvial and coastal components of the studies. 2.2 How to use this guidance Figure 2-1 shows the structure of this guidance document, and how the different chapters relate to different phases of a flood modelling project. For studies to be carried out later in a Flood Risk Management Planning cycle, Responsible Authorities may wish to carry out the 2 Formerly WaPUG Flood Modelling Guidance for Responsible Authorities v1.1 8
