The hydraulic geometry, runoff and sediment transport processes were studied during the 1991 summer season in two small pyroclastic drainage basins on Deception Island, South Shetland Islands. This study addresses three questions regarding: 1

Measurements and observations comprised all energy balance components and meteorological conditions in the course of the snowmelt period, may and june 1995, as well as intra- and subnival meltwater flows and the formation of a saturation zone within
to meltwater accumulation areas in drainage basins. Neither permafrost nor extreme meteorological conditions are prerequisite to slush torrents.
