Abstract: | Water losses due to transpiration and evaporation of intercepted water were measured using a “natural” lysimeter in the Hafren forest of central Wales, and were compared with estimates of potential evaporation calculated from meteorological observations. Given certain assumptions concerning the forest canopy, the lysimeter observations were used to estimate runoff from the experimental catchment of the Upper Severn, within which the lysimeter is sited; this estimate agreed well with observation. |
