Determination of sediment dynamics in torrential watersheds at different spatial and temporal scales under changing climatic conditions
Abstract
Processes like fluvial flows and debris flows can represent extreme events in torrential catchments, causing regularly loss of lives and substantial damage to settlements and infrastructure in mountain regions. There are two major shortcomings of current approaches that limit a more reliable assessment of climatic and topographic controls on torrential events in Austria: (1) the factors influencing sediment availability are poorly understood, and (2) most approaches neglect the actual initiation mechanism and its connection to hydro-meteorological trigger conditions. In this follow-up project we aim to improve both aspects. Building on an exceptional rich time-series of torrential events in Austria and on the outcomes of the DEUCALION II project (ACRP 7th call) on hydro-meteorological trigger conditions over long time scales, we want to investigate the missing geomorphological component and develop a coupled hydro-meteorological / geomorphological framework for the assessment of torrential flows in Austria.
