For the dam above, assume a drain gallery exists, reducing uplift linearly from full hydrostatic at the heel (( \gamma_w \times H )) to zero at the toe.
Dams are among the most impressive feats of civil engineering, acting as vital infrastructure for water supply, flood control, and hydroelectric power. However, managing millions of cubic meters of water requires a deep mastery of . fluid mechanics dams problems and solutions pdf

Water Force ( cap F sub cap H Overturning Moment ( cap M sub cap O Dam Weight ( Resisting Moment ( cap M sub cap R (Likely unsafe, as it is below the typical threshold).

, determine the factor of safety against overturning when the reservoir is full." B. Uplift and Seepage wide at the base (triangular section)
Water seeping under the dam creates an upward force that can destabilize the structure.
Total hydrostatic force normal to surface: [ F = \rho g \barh A = 1000 \times 9.81 \times 15 \times 30.92 ] [ F = 1000 \times 9.81 \times 463.8 = 4,548,000 , \textN \approx 4.548 , \textMN ]
