  2. Risk-informed dam safety management: motivation  Dam safety legislation influenced by past dam failure events.  EU Directives: Flood risk and Critical Infrastructure Management.  International dam safety guidelines. Picture: Failure of Tous Dam, Valencia, Spain, 1982 2

  3. Risk-informed dam safety management: process in Spain  Spain is the 9 th country in number of large dams. 30000 Source: ICOLD Register of dams 25000 23842 20000 Number of dams 15000 9265 10000 5102 5000 3116 1392 1305 1166 1114 1082 976 800 713 607 572 542 507 335 0 3

  8. CASE EXAMPLE A: PORTFOLIO OF 3 DAMS OWNED BY THE GOVERNMENT OF EXTREMADURA (SPAIN) 40 dams in Extremadura region owned by the regional government. Risk analyses applied to 3 dams: • Hervás dam (2000) • Membrío dam (1960) • Jaime Ozores dam (1962) Picture: Hervás (left) and Jaime Ozores dam (right), Spain 8

Surveillance improvement of uplift pressures with piezometers. dam 3. Improvement of spillway gates reliability. 4. Drainage system improvement under the spillway. 5. Emergency Plan focused on protecting downstream WTP. 6. Remote spillway gates operation. 7. New operation rules during flood events. 8. Reinforce parapet wall to increase dam crest level. Membrío 1. Emergency Action Plan implementation. dam 2. Public risk awareness campaigns 3. Dam surveillance improvement. 4. Drainage system improvement at downstream dam face. 5. Installation of monitoring devices (piezometers) El Horcajo 1. Lowering the spillway crest by 1.65 meters dam 2. Upgrading monitoring 3. Emergency Action Plan implementation 4. Improving dam foundation 5. Public risk awareness campaigns 11

  12. CASE EXAMPLE A: PORTFOLIO OF 3 DAMS OWNED BY THE GOVERNMENT OF EXTREMADURA (SPAIN) Results from risk models were used to prioritize a set of 18 dam safety measures 12 Variation of risk in a fN graph following the proposed implementation sequence.

  18. Lessons learned  Better knowledge of the system,  Enhanced emergency management,  Capacity building from real cases,  Improved risk communication to the public,  Improved information for defining activities for dam operation and maintenance ,  Better knowledge of business/governance risks . 18

  19. Dam Safety Risk Governance: the way forward Halpin and Escuder (2015): in the dam safety industry , very few organizations have implemented risk-informed governance, regardless of how obvious the benefits may seem As a matter of fact, the vast majority of industry worldwide are ‘non - doers’ in the sense of providing a rational framework for identifying, analyzing, evaluating, and managing risks 19

  20. Dam Safety Risk Governance: the way forward • A changing society, environment and regulatory context . • Highly dynamic and complex scenarios  participation of all concerned actors. • A new and integrative risk paradigm provides dam owners with information that is essential to establish strategies for dam safety management. Successful pilot cases  first steps of a journey for dam owners, aiming at achieving efficient, transparent and robust dam safety governance. 20
