Flow prediction in high altitude ungauged catchment: a case study in the Italian Alps (Pantano Basin, Adamello Group) / D. Bocchiola, C. Mihalcea, G. Diolaiuti, B. Mosconi, C. Smiraglia, R. Rosso. - In: ADVANCES IN WATER RESOURCES. - ISSN 0309-1708. - 33:10(2010), pp. 1224-1234. [10.1016/j.advwatres.2010.06.009]
Abstract:
We develop a simple model to evaluate the daily flow discharges in the ablation season for the 11 km2
Pantano basin in the Retiche Italian Alps, based upon the data gathered during a three years field campaign.
The Pantano basin embeds the Venerocolo debris covered and the Avio debris free glaciers, covering
2.14 km2 in the Adamello Group, where the widest Italian glacier Adamello is located. First, degree-day
models based upon air temperature are tuned to calculate snow and ice melt at daily scale. Glaciers’
meteorological data are collected from an automatic weather station (AWS), operating on the glacier during
summer 2007. The melt factors in the debris covered areas of the glacier are estimated against debris
thickness, using a data driven parameterization. The flow discharge from the catchment is estimated using
semi distributed flow routing for the ablation seasons of four years, from 2006 to 2009. The predicted
discharges are compared to those derived from inverse reservoir''s routing at the Benedetto lake, catching the
basin outflow. The proposed approach is valuable as a tool to investigate the hydrology of poorly gauged
glacierized areas, including those with debris covered ice, widely diffused and yet poorly understood.
Pending accurate parameterization the approach is usable for water resources evaluation and for long term
assessment of the climate change impact on the glacierized areas within the Alps.
