Workshop on Snow modelling

On 27-28 January SMHI organised a workshop on snow modelling.

The workshop saw participants from Universities and research institutes in Sweden (KTH, LTU), France (CEMAGREF) together with representatives from the water power industry in Sweden (Vattenfall, Vattenregleringsföretagen) and Norway (Statkraft).

The workshop started on Thursday afternoon with a number of presentations which dealt with different aspects of snow modelling. See below for detailed programme. The documentation can be found in the column to the right.

The Friday was dedicated to discussions about different ways to improve the modelling of snow, and consequently reduce the error in spring flood predictions. Friday’s discussion was summarised in a white paper on snow modelling.
