Reedbed evapotranspiration rates in England

Measurements of evapotranspiration from contrasting stands of Phragmites au stralis [ET(Reed)] were obtained over several years at three sites within E ngland between 1994 and 1998, A comparison with published ET(Reed) values s howed the UK rates to be considerably lower than those measured in continen tal Europe. From the ET(Reed) data monthly crop coefficients [K-c(Reed)] ha ve been developed, which when used with Reference Crop Evapotranspiration w ill enable reedbed water use to be determined. Due to the differences in st udy site characteristics, values for K-c varied widely, and it was not cons idered appropriate to combine results to produce a single set of monthly me an values. However, suggestions are made regarding the application of the K -c(Reed) values to wetland design. Copyright (C) 2001 John Wiley & Sons, Lt d.
