Assessing interception losses and implications for SuDS designClick here to download PDF

This presentation considers the factors which have the ability to influence interception losses, drawing upon monitoring outputs from a scheme in London. It will also reflect upon how losses are normally represented within design and how current approaches could be adapted in the future to make allowance for losses as part of the SuDS design process.
