Year number 1 is in this case: ________

Planned Capital Costs:
(i.e. information from the latest design study before it was firmly decided to build the project)

Actual Capital Costs:

5. Benefits

Question: How does actual performance compare with performance expected at the time of project planning and design? 

Note: Years refer to years after start of commercial operation

6. Environmental Data

Question: What were the main ecosystem components and functions positively or negatively affected by the project?
Were mitigation measures planned and how effective were they?

Question: What were the design and operation measures taken to address environmental impacts?

Question: Is there a hydrological model for the river system?
Circle answer: (yes) (no)

Question: Is the hydrological model for the river system able to measure?
Yes / No

Question: What is the time step resolution of the hydrological model?

Question: Is there an environmental monitoring programme for the downstream sector?
Circle answer: (yes) (no)

Question: If yes, what parameters are monitored and with what frequency?

7. Flood Control Data

please tick boxes or circle yes/no responses where appropriate

Question: How does actual performance compare with performance expected?

Relative importance of flood protection to other dam functions: Primary / Secondary

If answer to above is Secondary, then is there ever a conflict of interest between operations for flood control and other functions?
What are the principles used to resolve this? (ie. Draw down of dam in September if floods expected in October of each year)
