This session, with a roundtable format, will deal with a rising issue in many countries. Implementing more modern standards for dam safety means launching upgrade projects for risk mitigation or remedial works o existing infrastructures. Aging, new safety standards, the rising value of downstream assets, etc., demand risk reassessment and sometimes new investments under the constraints of non-stop operation. Dam safety regulation does not exist in many countries, and international practices are being observed as a trail to follow. This new challenge is more frequent and worthy of discussion among panelists, after the presentation of a keynote highlighting the main challenges.
