This document provides an addendum to the updated ‘Pumped catchments – Guide for hydrology and hydraulics’ (Report SC090006/R003, 2012). As part of the guidance update, it was decided that practitioners in the operating authorities responsible for flood risk management in low lying catchments would benefit from being able to view illustrative examples. This document presents a worked example which compares results for assessing flood risk derived from the new method to that obtained by applying the processes set out in the earlier guidance (The Hydraulics and Hydrology of Pumped Drainage Systems – An Engineering Guide, Report SR 331 November 1993).
