||Environmental issues in dam projects.
- Contributions of dam projects to meet human and environment needs.
- Environmental evaluations: biological, geophysical, political, social, economic and financial, etc., and water quality.
- Operational appraisal: case histories and comparison with original objectives.
- Public awareness.
||Ageing of dams and remedial measures.
- Detection of ageing.
- Evaluation of ageing process and its consequences.
- Remedial measures to mitigate the ageing process.
- Preventive measures in design, construction and operation to limit ageing process.
Ageing = changes with time of structural properties of dams (geometrical and physical-mechanical, hydraulic, thermal, etc.) Which influence the structural safety, occurring under normal operational conditions.
||Dams on difficult foundations.
- Effect of difficult foundations on dam design and construction (water-tightness, stability, liquefaction, etc.)
- Unusual treatment of foundations.
- Foundation behaviour on first filling and during operation.
- Unsatisfactory behaviour of foundations: remedial measures and results.
||New developments for fill dams and fill cofferdams.
- Design and construction considerations of low quality fill materials and impact of extreme weather conditions.
- New use of man-made materials for reinforcement and drainage, excluding impervious elements.
- Design for overtopping and flow-through.
- Special problems with fill dams in narrow valleys.
