Optimization of the water level dynamics of the lake Mondsee - hydrological considerations
Abstract
The feasibility study 2018 for updating the weir operating order showed that short-term precipitation forecasts do not provide a suitable possibility for advance control of the Mondsee water level. For this purpose, the forecast interval of 1 to 2 days is too short and advance drawdown of water levels is not possible in the short time interval. The objective of this follow-up study is to examine to what extent an improvement of the optimal water level - including all stakeholder interests - can be achieved by a seasonally differentiated weir operation regulation. The determination of the optimal water level requires the inclusion of the different user interests such as flood protection of the residents, tourism (bathing use), lake navigation and fishery (ecology), as well as for the downstream area the power plant operators on the Seeache and the effects on the water level of Lake Attersee. The lake water balance (inflow / water level / outflow) is calculated with different retention scenarios and compared according to multi-objective criteria with the involvement of the stakeholders.
