) and its . By ensuring the dam’s weight (vertical force) is sufficient to keep the resultant force within the "middle third" of the dam’s base, they prevent overturning and sliding. 2. Seepage and Uplift Pressure

(a) The resultant hydrostatic force, F_R , is F_R = ρ g h_c A = (62.4 lb/ft³) × (200 ft / 2) × (200 ft × 1 ft) = 1.25 × 10⁶ lb/ft . This public link is valid for 7 days

Engineers construct graphical flow nets consisting of flow lines (paths of water particles) and equipotential lines (lines of equal head) to solve this equation. The total seepage discharge ( ) per unit width is calculated using: Can’t copy the link right now
