Recently observed changes in glacierized areas significantly influences on water circulation features in those regions. Project assumes hydrological research in Waldemar River catchment as the example of the High-Arctic glacierized basin. Those investigations began in late 1970’s. From that date substantial changes in catchment characteristic are observed (e.g. decrease degree of glaciation). Glacier-fed river characteristics are well recognized all over the globe. But still there is a need to define how contemporary deglaciation processes affects the water circulation cycle. Basics hydrological features in Waldemar River Catchment are continuously investigated since 1995. In the close feature, a HIWRC programme will be expanded to include research of major glaciohydrological processes in catchment (e.g. internal glacial drainage and it contribution to total outflow). Study assume measurements in a few river points – both in close vicinity of glacier (with no other than glacial water source tributaries) and in lowest part of catchment (with periglacial tributaries).
