Raw macroinvertebrate data, 2016 and 2017, for the Borgne d'Arolla
|Persistent Identifier (PID)
Raw macroinvertebrate data sampled in the Borgne d'Arolla South-West Switzerland, to assess the impacts of hydropower upon in stream macro invertebrates. The data are reported in the following two manuscripts:Gabbud, C., Robinson, C. and Lane, S.N., 2019. Summer is in winter: disturbance-driven shifts in macroinvertebrate communities following hydroelectric power exploitation. Science of the Total Environment, 650, 2164-80.Gabbud, C., Robinson, C. and Lane, S.N., 2019. Sub-basin and temporal variability of macroinvertebrate assemblages in Alpine streams: when and where to sample? Hydrobiologia, 830, 179-200.The data may be used upon the strict condition that the above manuscripts are cited in any presentations/reports/articles/communications arising from the use of the data.The above articles explain how the data were acquired.
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.
