Question

Given below are two statements
Statement I: Free board is the additional height of the dam provided as a safety factor to prevent overtopping due to unexpected runoff or by wave action.
Statement II: Free board is the vertical distance between the designed water elevation and the elevation of the top of the dam before settlement.
In light of the above statements, choose the most appropriate answer from the options given below

• A. Both Statement I and Statement II are correct
• B. Both Statement I and Statement II are incorrect
• C. Statement I is correct but Statement II is incorrect
• D. Statement I is incorrect but Statement II is correct

Hint:

Always remember that freeboard is a safety limit that must remain active throughout the lifetime of the dam.
Because earthen structures settle over time, freeboard is always measured relative to the settled height, not the newly constructed pre-settlement height.
