The last decade has been a period of rapid advances in glacier hydrology and hydrochemistry. These have resulted from the application of new technologies to the direct observation of englacial and subglacial drainage systems via boreholes, from theoretical advances and from increased interactions between fieldworkers and modellers. This collection of papers captures the spirit of these advances highlighting new methodologies, the change in character of hydrological models from lumped conceptual models to physically based, distributed models, and the changing role of field studies in glacier...
