Many new UK housing estates are required to be built with Attenuation Ponds / Sustainable Drainage schemes as part of their development. These are to control rain water runoff during storms and consist of a pond surrounded by an embankment with a controlled release structure to slow down drainage of the water to the river system.
The relevant features might be . Low or normal water level of pond . High water level or top of embankment . Land use/vegetation between low/high water marks is water tolerant/marsh plants . Structures for water input and output - often brickwork and filter screens round a pipe. Has anyone any experience of mapping and tagging such a structure? Are there any examples of where this has been done? Steve
