Fluvial morphology and streamflow on Deception Island, Antarctica

Research output: Contribution to journalArticlepeer-review


The empirical relationship between the depth, velocity and width exponents- f>m>b in channels with non-cohesive material is valid for the studied area. Width is relatively conservative during increase of water discharge. Runoff was almost continuous for about 40 days, showing a strong association between streamflow and temperature. Two main periods are distinguished in the annual hydrological regime: 1. Runoff during a short melting period of snow and glaciers. 2. Snow cover and frozen period of the entire drainage area. Temperature is the main factor affecting the hydrological regime of the rivers and snow availability during the summer season determines discharge water volumes in the non-glaciated basin. The specific discharge value was 3.42 l/sec/km2.
