Lay summary

Dieses Projekt wird neue und weiterentwickelte Methoden bereitstellen, um in alpinen Einzugsgebieten die Zielkonflikte zwischen der Wasserkrafterzeugung und den Bedürfnissen von stromabwärts von Staudämmen gelegenen aquatischen Ökosysteme zu analysieren.

Zum einen sollen diese Methoden die Grundlage bilden für Richtlinien für Wasserkraftproduzenten und Gesetzgeber bezüglich der potentiellen negativer Auswirkungen des Systembetriebes auf die Umwelt sowie der Nachhaltigkeit des zukünftigen Betriebes. Zum anderen zeigen diese Methoden auch Kriterien zur möglichen Verbesserung der Betriebsstrategien im Rahmen der Regulierungs-, Markt- und Nachfragebeschränkungen auf, welche alle die Produktion auf höchstem Niveau halten bei verbleibender Nachhaltigkeit für das Flussökosystem.

Abstract

This project will provide new and advanced methods for the analysis of medium-to-long term tradeoffs between hydropower production and eco-hydrological dynamics in Alpine catchments under current and projected climate. The methods should reach the level of applications to existing hydropower systems, thus providing the basis for guidelines to hydropower producers and legisla-tors about the potential negative consequences of system operation on the environment, the sus-tainability of the operation in the future, the possible improvement of operation strategies under regulation, market and demand constraints, all of which maintain production and remain sus-tainable for river ecosystems.The four main objectives of the project are:(1)to develop system tools and methods (based on observations and models) for quantifying the long-term balance of hydropower production and environmental degradation in Swiss Alpine rivers and their associated ecosystems, and provide an aid to hydropower producers and regu-latory authorities as to which environmental variables (biotic and abiotic) present and future operation of hydropower systems potentially degrade, and to which extent is the level of degra-dation a challenge to the sustainability of the operation;(2)to address explicitly the issue of DEF releases (dynamic environmental flow, as compared to the present law-enforced environmental flow concepts) and their benefits from hydrological, geomorphological, ecological viewpoints (for aquatic insects, fish, riparian vegetation, river morphology, sediment fluxes, nutrient fluxes, etc.), and the potential consequences of DEFs on the production and profitability of hydropower systems;(3)to provide exemplary case studies on long-term assessment of hydropower potential as required by the Energy Strategy 2050 under projected climate change with increased power production and river conservation goals, which specifically aims at investigating the involved uncertainties, the potential long-term effects on river ecosystems from the viewpoint in (2), and the margin for real optimization potential for hydropower producers (acting individually or jointly);(4)to develop a prototype framework to model the complexity of hydropower systems and their management, which can explicitly account for environmental aspects through novel indicators, value functions and scenario analysis, while being constrained by technical, economic, and institutional controls and also accounting for intrinsic (e.g. climate and response of natural systems) and extrinsic (e.g. demand, market and institutional boundary conditions) non-stationarities.
