Kirby C., Newson M.D., Gilman K. Plynlimon research: The first two decades

Wallingford: Institute of Hydrology. – 1991. – 196 p. (IH Report No. 109) More than twenty years ago the Hydrological Research Unit, the fledgling Institute of Hydrology, based in the Thames Valley, launched an ambitious project on the eastern slopes of Plynlimon in the uplands of Wales. The original aim of the Plynlimon catchment experiment was to collect data which could resolve the question of the water use of conifer forests. It has subsequently developed into a multi-disciplinary project which has underpinned hydrological research within IH up to the present day and has an important role for the future.The British Uplands and the Plyalimon study.
