Currently, there is not a specific UE Directive about Dam Safety Management but…

DIRECTIVE 2007/60/EC ON THE ASSESSMENT AND MANAGEMENT OF FLOOD RISKS DIRECTIVE 2008/114/EC — IDENTIFICATION AND DESIGNATION OF EUROPEAN CRITICAL INFRASTRUCTURES AND ASSESSMENT OF THE NEED TO IMPROVE THEIR PROTECTION

  • 600 mm of average yearly

precipitation

  • 2200 mm/year in Santiago
  • 120 mm/year in Cabo de

Gata

  • Over 1200 large dams in

Spain (9th in the world):

  • Public

DAM SAFETY GOVERNANCE IN ARGENTINA

OBJETIVES

  • Capacity-building in risk-informed dam safety management.
  • Prioritization of investments informed by risk results.
  • Strategic action plan to apply risk-informed decision making in other dams in

the country.

  • Support to promote the development of a Dam Safety Law in Argentina.

Dam Safety Regulator Organism in Argentina

  • Regulates safety of main hydropower dams in

the country (32 dams).

  • Advisory body for other dams.

FAILURE MODES IDENTIFICATION

  • 50 participants from different public and private entities related with safety in

the system of dams.

  • 20 failure modes were identified.

DAM SAFETY GOVERNANCE IN USA

  • Public agency in charge of flood protection systems

(including 700 dams with multiple purposes).

  • Self-regulated.

Risk-informed Dam Safety Program Purpose: To protect life, property, lifelines, and the environment by ensuring that all dams are designed, constructed, regulated, operated, and maintained as safely and effectively as is reasonably practicable.
