GREENHOUSE HYDROLOGY

Hydrological processes are an integral component of both global climat e change arising from increasing concentrations of greenhouse gases an d the assessment of subsequent terrestrial impacts. This article exami nes the potential sensivity of water resources in the UK to climatic c hange as exemplified by the 1988-92 drought. The representation of hyd rological processes at three distinct model scales is then discussed w ith reference to global hydrology, regional downscaling and catchment- scale responses. A final section speculates on future directions of re search for an emerging greenhouse hydrology.
