Drought and Low Flow Projections – learning from the past for managing the future
Abstract
The aim of the project is a comprehensive analysis of drought and low flows in Central Europe (Austria and neighbour regions) under past, present and future conditions. The approach aims to overcome the limitations of current trend analysis and climate projections by a joint analysis of streamflow anomalies with meteorological drivers and tree ring records in the longer past, including the pre-instrumental period. This new understanding of drought generation in the climate and hydrological system will be used (i) to put current extreme low flow conditions into the context of climate change during the past millennium, and (ii) to develop improved models for predicting future drought conditions. The results target government agencies at both state and federal levels and private businesses and the main benefit will come from reduced costs to the government budgets as well as to private stakeholders due to more efficient management decisions.
