Catchment
The SuDS Manual published by CIRIA in 2015 defines a 'catchment' as: 'The area contributing surface water flow to a point on a drainage or river system. Can be divided into sub-catchments.'
A sub-catchment is: 'A division of a catchment, to allow runoff to be managed as near to the source as is reasonable'
Catchment flood management plans (CFMP’s) aim to establish flood risk management policies which will deliver sustainable flood risk management for the long term across a catchment. For more information see: Catchment flood management plan.
Culvert, screen and outfall manual, (CIRIA C786) published by CIRIA in 2019, defines catchment as: ‘The area of land that drains to a given point on a river, drainage system or other body of water.’
It defines a flashy catchment as: ‘A catchment with a watercourse that rises immediately following a period of rain.’
NB In relation to human geography, a catchment area is the area from which a city, service, institution etc. attracts the population that it serves.
