Hillingdon SuDS Design & Evaluation Guide

Overview 2.2 The ground

Overview 2.2 The ground becomes saturated After a while the surface of the landscape Where the ground is permeable, water can absorb no more water. begins to soak into lower soil profiles and then the underlying geology. This is called infiltration and is common on sandy, gravelly and limestone soils. In landscapes with infiltrating soils, after interception losses have taken place, most rainwater is lost by soaking into the ground. 5 London Borough of Hillingdon SuDS D & E Guide © 2018 McCloy Consulting & Robert Bray Associates

Where the ground is impermeable, water begins to trickle and flow across the surface, collects in natural depressions, and is stored in wetlands. These natural features attenuate the rate and volume of flow of rainwater running off the landscape. These flows are called natural or greenfield runoff. Overview Surface flow rates are small at first, but increase with higher intensity rainfall events. The volume of runoff will generally be greater with increased rainfall intensity and duration. 6 London Borough of Hillingdon SuDS D & E Guide © 2018 McCloy Consulting & Robert Bray Associates
