The Forest Hydrology programme involves a number of collaborative studies of the effects of forestry on flood flows. These include long-term studies of the hydrological effects of upland conifer forests in research catchments at Coalburn in north England and Balquhidder in mid-Scotland.
The results indicate that while some forestry practices and phases of forest growth affect peak flows within small headwater catchments, the impacts deminish at the larger catchment scale.
Forests the world over, have long been associated with helping to reduce flooding. Most flooding disasters have been partly blamed on the effects of deforestation.
