Q2) A reservoir is to be formed in a river valley by building a dam across it. The entire area that will be covered by the reservoir has been contoured and contours drawn at 5-m intervals. The lowest point in the reservoir is at a reduced level of 118.0 m above datum, whilst the top water level will not be above a reduced level of 148 m. The area enclosed by each contour and the upstream face of the dam is shown in the table below. Contour (m) Area enclosed (m²) | Contour (m) Area enclosed (m2) 120 4 600 145 13700 125 7100 150 15100 120 0800
