Flood prevention
Flood prevention covers structural defenses (dams, levees, drainage), nature-based solutions, land-use regulation, insurance, and early warning systems used to reduce flood risk; by 2050, 1.6 billion people are projected to be at risk of flooding.
Flood pulse
The flood pulse is the periodic inundation and drying of a river's floodplain. The 1989 Flood Pulse Concept by Junk, Bayley, and Sparks holds it drives river-floodplain productivity.
Flood risk management plan
A flood risk management plan (FRMP) is an EU document under the 2007 Floods Directive setting out each Member State's flood prevention, protection, and preparedness measures.
Flood risk mapping
Flood risk mapping is a geospatial method that identifies flood-prone areas and combines modeled flood extent with exposure data to support land-use planning, insurance rating, and flood risk management.
Flood routing
Flood routing is the group of methods for determining the shape and timing of a flood wave as it moves along a channel, from a known hydrograph at another point.
Flood runoff
Flood runoff: water from precipitation flowing over land surfaces, including paved urban surfaces, into streams and causing high flow. Also called stormwater or urban runoff; generated by infiltration-excess or saturation-excess overland flow.
