The purpose of ICOLD Bulletin 169 is to assess the role of dams and reservoirs in adapting to the effects of global climate change, determine the threats, and potential opportunities, posed by global climate change to existing dams and reservoirs, and then recommend measures to mitigate against or adapt to the effects of global climate change. This bulletin is organized in chapters that include the following:
a description of what is at risk when considering dams, reservoirs and related water resources
facts and uncertainties with climate evolution, mainly based on past observations analysis
framework and method for assessing climate induced impacts and risk at watershed scale
other drivers besides climate change that can affect the balance between resources and needs: demography, technology, sedimentation
climate-driven opportunities for new storage
emissions of greenhouse gases associated to reservoirs and water resources
adaptation strategies and case studies from different regions of the world and illustrating different water resources systems situations
recommendations
ICOLD recommendations (chapter 10) address three broad themes:
Recommendation 1: Adopt a whole-of-system approach.
Recommendation 2: Apply an adaptive management process.
Recommendation 3: Collaborate with a wide range of disciplines, interest and stakeholders (including engineers alongside decision makers, politicians, natural resource scientists, social scientists, economists and the greater community) in the assessment of enduring and effective adaptation options.
L'objectif de ce ICOLD Bulletin 169 est d'evaluer le role des barrages et reservoirs dans l'adaptation face aux effets du rechauffement climatique, de determiner les risques de meme que les opportunites potentielles, imposees par le rechauffement climatique aux reservoirs et barrages, puis recommander des mesures d'attenuation ou d'adaptation aux effets du changement climatique mondial.
Le present bulletin est structure en plusieurs chapitres comprenant les elements suivants:
la caracterisation des risques pour les barrages et reservoirs, et pour la gestion des ressources en eau associees
les constats et incertitudes lies a l'evolution du climat, principalement fondes sur l'analyse des observations anterieures
les principes methodologiques des etudes d'evaluation des impacts et des risques induits par l'evolution du climat a l'echelle du bassin versant
d'autres facteurs que le changement climatique qui peuvent affecter l'equilibre entre les ressources et les besoins : demographie, evolution technologique, sedimentation
l'opportunite de creer de nouvelles reserves de stockage pour augmenter la resilience des systemes aux effets climatiques
un point sur les emissions de gaz a effet de serre imputables aux reservoirs et aux ressources en eau
des principes de strategie d'adaptation et des etudes de cas provenant de differentes regions du monde, illustrant differentes situations des systemes de gestion des ressources en eau
des recommandations.
Les recommandations generales portent sur trois grands themes :
Recommandation 1: adopter une approche systemique d'ensemble
Recommandation 2: Appliquer un processus adaptatif de gestion
Recommandation 3: Collaborer avec un large eventail de disciplines, et de parties prenantes (ingenieurs, decideurs, elus, specialistes des ressources naturelles, specialistes des sciences sociales, economistes et la collectivite dans son ensemble) dans l'evaluation des options d'adaptation durables et efficaces.

Schweitzer Klassifikation
The Commission Internationale des Grands Barrages (CIGB) / International Commission on Large Dams (ICOLD) is a non-governmental International Organization which provides a forum for the exchange of knowledge and experience in dam engineering.
The Organization leads the profession in ensuring that dams are built safely, efficiently, economically, and without detrimental effects on the environment. Its original aim was to encourage advances in the planning, design, construction, operation, and maintenance of large dams and their associated civil works, by collecting and disseminating relevant information and by studying related technical questions.
Since the late sixties, focus was put on subjects of current concern such as dam safety, monitoring of performance, reanalysis of older dams and spillways, effects of ageing and environmental impact. More recently, new subjects include cost studies at the planning and construction stages, harnessing international rivers, information for the public at large, and financing.
