ABSTRACT
Many contemporary approaches to flood risk management (FRM) are looking to recreate these more natural mechanisms. This chapter discusses some of the catchment-wide issues and introduces a range of contemporary approaches for catchment and community FRM. The green curve represents a ‘greenfield’ condition in which levels of infiltration and attenuation are high, causing the large volume of rainfall to take considerable time to move through the catchment. When aligned up a slope/across contours, the channels created can direct water quickly down to lower catchment areas and lead to flooding. Sea walls protect many of the world’s coastlines and cities from flooding by absorbing wave energy and reducing erosional processes. Par Docks in Cornwall, England was used as the study area for the research, as it is representative of sites suffering threats from storm surges, sea level rise, and both fluvial and pluvial flooding.
