Apologies for any cross posting.

Dear colleagues,

We would like to invite you to submit your abstracts to the following EGU General Assembly 2023 session (HS10.10): 

Ecohydrological perspective on hydropeaking: from process understanding to implementation of river-focused mitigation actions 

Where to submit

You can submit your abstract to our session (HS10.10) by clicking https://meetingorganizer.copernicus.org/EGU23/session/45489

 

Session information

Hydropeaking- the discontinuous release of turbined water in response to peaks in energy demands, causes artificial flow and river stage fluctuations downstream of hydropower plants. Such periodic flow fluctuations have adverse consequences for the hydrological cycle, sediment transport processes, surface water-groundwater interaction, and the biotic integrity of the river ecosystem. It is, therefore, of utmost importance to improve our understanding of the processes affected by hydropeaking over multiple spatial and temporal scales. Such understanding will facilitate the design and implementation of successful mitigation measures (e.g., hydrological and morphological) for affected river systems.

This interdisciplinary session aims to bring together different disciplines and research aspects relevant to the field of hydropeaking, for example ecohydraulics. The range of topics covered will be broad, from laboratory scale experiments to catchment scale studies, from time series analysis of parameters affected by hydropeaking to ecohydrological studies. Presentations focusing on modeling and experimental works are welcome, as well as those on case studies in which the adverse effects of hydropeaking are characterized and mitigation actions are planned or implemented.

In particular, questions of interest can relate to the effects of hydropeaking on:

- Mass, solute, and energy transport along the river network and between surface water and groundwater

- Effects on substrate and sediment transport processes

- Biogeochemical processes in the hyporheic zone

- The riverine ecosystem and its responses from individual to population level for different groups of biota

- The effectiveness of river restoration projects

- Decision-making processes in energy production and mitigation measure implementation

- Emission of greenhouse gases and the carbon cycle

Relevant dates 

The deadline for abstract submission is 10 January 2023, 13:00 CET. Participants who are eligible to apply to a Travel Support grant should submit their abstract by the early deadline of 1 December 2022, 13:00 CET. Instructions for abstract submission can be found here.   

 

We hope to see you in Vienna!  

 

Kind regards,

Gabriele Chiogna, Marie-Pierre Gosselin, Daniel Hayes, Mauro Carolli, Ulrich Strasser
