WLV Oberwölz - Modelling future runoff and sediment transport in alpine torrents

The discharge regime of the Schöttlbach will change from a nival to a more pluvial regime (decreasing importance of snow storage and snowmelt) in the coming decades due to the predicted temperature increase. With regard to sediment mobilisation and sediment load, a disproportionate increase in sediment load can be expected in the future if the frequency of disturbance events falls below the time required for stabilisation of the torrent system. However, this only applies to catchments with high to almost unlimited sediment availability.
