Future Developments - Needs

Small Dams

Monitoring – Visual Inspection, Maintenance, Emergency Action Plan

Large Dams

Embankment – Improvement of applicable material behavior description under dynamic excitation

Pore pressure accumulation, seepage and stability analyses need coupling

Concrete Dams

Simultaneous excitation shows conservative results System and radiation damping under high acceleration

Nonlinear system analysis in the time domain need appropriate radiation
