a. Calculate the ground elevation at the top of the dam on October 9, 2020 and on April 24, 2021 considering the effect of curvature and
atmospheric refraction.
b. Calculate determine the horizontal distance between the total station and the reflector on October 9, 2020 and on April 24, 2021.
C. Investigate if there is movement at the dam.
Transcribed Image Text:6. The top of the dam have been regularly monitored with a total station for possible movement and or settlement. Investigate if there is
movement and or settlement on top of the dam using the provided data and illustrations. Refer to the figures below. The elevation of the point
where the instrument was set-up is dce.fge M.
Note: substitute the letters with the corresponding number of your ID number for the elevation of the point where the instrument was set-up.
