OBJECTIVE AND SCOPE
This guidance is the output of a research study into the available systems. The objectives were to
categorise and review these, and to develop a systematic method for choosing appropriate defences for
various scenarios and using them in a safe manner. As a result of the limited performance information
on the available systems and the urgent need for guidance, this document is being published as an
interim guidance document. The Environment Agency is working closely with the recently formed
Flood Protection Association in the development of performance assessment and product accreditation
protocols and plans to review this interim guidance document during 2004.
