Resilience measures

Name Definition
Floodwall A floodwall is a primarily vertical artificial barrier designed to temporarily contain the water of a river or other waterway which may rise to unusual levels during seasonal or extreme weather events. They can be realised as mobile flood protection walls, which are build up before a storm event occurs ...
Maintenance of hydraulic structures of the storm drainage system Set up regulations on maintenance of the hydraulic structures and drainage network infrastructures so that their maximum conveyance capacity will be unlimited. Regular maintenance of hydraulic structures, is another crucial part of flood control. (Wikipedia, Flood control, accessed on Sept. 2016)
Aquifer recharge Aquifer recharge is achieved by adding surface water in basins, furrows, ditches, wells or other facilities where it infiltrates into the soil and recharges the aquifers. Aquifer recharge allows water retention underground. During flood events, water can be redirected to aquifer's area. (Bouwer H., 2001)
Permeable paving Permeable paving is a range of sustainable materials and techniques for permeable pavements with a base and sub base that allow the movement of water through the surface. It aims to attenuate the surface runoff. In addition, this effectively traps suspended solids and filters pollutants in the soil. Besides pavements ...
Cascading flood compartment system The “system of cascading flood compartments” combines area prevention with constructional solutions. The idea is to (re)build a second dikeline of polders behind the primary dike, thereby creating a system of different compartments. Polders are low lying areas enclosed by embankments or dikes. In the case of a dike overflowing, ...
Water square The water square combines water storage with the improvement of the quality of urban public space. It makes money invested in water storage facilities visible and enjoyable. When heavy rains occur, rainwater that is collected from the neighbourhood will flow visibly and audibly into the water square. Short cloudbursts will ...
Beach nourishment Beach nourishment is an adaptation technology primarily used in response to shoreline erosion, although flood reduction benefits may also occur. It is the process by which sediment (usually sand) lost through longshore drift or erosion. Beach nourishment is typically part of a larger coastal defense scheme. It is a soft ...
Dredging of watercourse The term dredging is used to refer to the systematic removal of accumulated material from river or other watercourse channels. In its most extreme form dredging may be used to re-align river channels creating linear, canalised watercourses. While implementing such a measure the cross section of channels and waterways is ...
Bioretention area A bioretention area is a stormwater treatment system that is a depression integrated into the landscape. A bioretention area captures runoff from an impervious surface and allows that water to infiltrate through the soil media. As the water infiltrates, pollutants are removed from the stormwater runoff through a variety of ...
Flood control dam A flood control dam is a dam built to catch surface runoff and stream water flow in order to regulate the water flow in areas below the dam. Flood control dams are commonly used to reduce the damage caused by flooding or to manage the flow rate through a channel. ...
Stormwater retention tank Stormwater tanks are an effective way of reducing peak flow and equalising flow rates from storm water runoffs in the sewer system. Placed strategically, stormwater tanks mean better utilisation of the existing sewer system, allow for intelligent management of storm water flows, and ultimately save on infrastructure investments. Stormwater tanks ...
