Interdisciplinary Reservoir Management : a Tool for Sustainable Water Resources Management

2021-04-18, Daus, Milan, Koberger, Katharina, Koca, Kaan, Beckers, Felix, Encinas Fernández, Jorge, Weisbrod, Barbara, Dietrich, Daniel R., Hofmann, Hilmar, Martin-Creuzburg, Dominik, Peeters, Frank

Reservoirs are a common way to store and retain water serving for a multitude of purposes like storage of drinking and irrigation water, recreation, flood protection, navigation, and hydropower production, and have been built since centuries. Today, few reservoirs serve only one purpose, which requires management of present demands and interests. Since each reservoir project will cause negative impacts alongside desired advantages both on a local, regional and global scale, it is even more urgent to develop a common management framework in an attempt to mitigate negative impacts, incorporate different demands and make them visible within the discourse in order to avoid conflicts from early on. The scientific publications on reservoirs are manifold, yet a comprehensive and integrative holistic tool about management of this infrastructure is not available. Therefore, a comprehensive and integrated conceptual tool was developed and proposed by the authors of this paper that can contribute to the sustainable management of existing reservoirs. The tool presented herein is based on the results from the interdisciplinary CHARM (CHAllenges of Reservoir Management) project as well as the condensed outcome of relevant literature to aid and enhance knowledge of reservoir management. The incorporated results are based on field, laboratory and empirical social research. The project CHARM focused on five different aspects related to existing reservoirs in southern Germany (Schwarzenbachtalsperre, Franconian Lake District), namely: sedimentation of reservoirs, biostabilisation of fine sediments, toxic cyanobacteria(l) (blooms), greenhouse gas emissions from reservoirs and social contestation, respectively consent. These five research foci contributed to the topics and setup of a conceptual tool, put together by the research consortium via delphi questioning, which can be found alongside this publication to provide insights for experts and laymen. Conceptualising and analysing the management in combination with quantitative and qualitative data in one descriptive tool presents a novelty for the case studies and area of research. The distribution within the scientific community and interested public will possibly make a positive contribution to the goal of sustainable water resources management in the future.

CHARM – Challenges of Reservoir Management : Meeting Environmental and Social Requirements

2018, Beckers, Felix, Haun, Stefan, Gerbersdorf, Sabine U., Noack, Markus, Dietrich, Daniel R., Martin-Creuzburg, Dominik, Peeters, Frank, Hofmann, Hilmar, Glaser, Rüdiger, Wieprecht, Silke

The project CHARM aims at contributing to a better understanding between reservoir management and its impact on the surrounding environment and the reservoir itself. CHARM is a multidisciplinary research project addressing five fundamental issues of reservoir management: sedimentation, biostabilization, harmful cyanobacterial blooms, greenhouse gas emissions, and societal implications. These issues are tackled through analytical approaches, field monitoring, laboratory experiments and numerical models, thus gaining insights into the involved processes at different scales. The project outcomes will support the development of reservoir management strategies to meet challenges related to increasing anthropogenic impacts on water bodies and to climate and demographic changes resulting in altered energy and water demands.
