For earth dams, the problem shifts from rigid body statics to seepage analysis. A typical solved problem involves:
Example Solution from a PDF: Given a homogeneous earth dam with a horizontal filter, hydraulic conductivity ( k = 10^-6 , m/s ), head difference ( H = 15 , m ), and a flow net with ( N_f = 4 ) flow channels and ( N_d = 10 ) potential drops. [ q = k H \fracN_fN_d = 10^-6 \times 15 \times \frac410 = 6 \times 10^-6 , m^3/s/m ]

Problem:
A concrete dam (( \rho_c = 2400 , \textkg/m^3 )) has a vertical upstream face. Height ( H = 20 , \textm ), width ( b = 1 , \textm ) (unit length into page). Base width ( B = 15 , \textm ). Water depth = ( H ).
Find:
(a) Total hydrostatic force on the dam.
(b) Overturning moment about the toe.
(c) Factor of safety against overturning (ignore uplift).
Solution:
(a) Hydrostatic force
[
F_h = \frac12 \rho_w g H^2 \times b = 0.5 \times 1000 \times 9.81 \times 20^2 \times 1
]
[
F_h = 0.5 \times 1000 \times 9.81 \times 400 = 1,962,000 , \textN = 1.962 , \textMN
]
(b) Overturning moment about toe
The hydrostatic force acts at ( H/3 = 20/3 \approx 6.667 , \textm ) above the toe.
[
M_\textoverturning = F_h \times \fracH3 = 1.962 \times 10^6 \times 6.667 = 13.08 \times 10^6 , \textN·m = 13.08 , \textMN·m
]
(c) Resisting moment from dam weight
Dam cross-section area = ( H \times B = 20 \times 15 = 300 , \textm^2 ) per meter length.
Weight per meter length:
[
W = \rho_c g \times \textarea = 2400 \times 9.81 \times 300 = 7.0632 \times 10^6 , \textN = 7.063 , \textMN
]
Center of gravity of rectangular section from heel (upstream face) = ( B/2 = 7.5 , \textm ).
Distance from toe = ( 15 - 7.5 = 7.5 , \textm ). Wait – careful: Heel is upstream, toe is downstream. For rectangular dam, CG is at B/2 from heel. So moment arm about toe = ( B - B/2 = B/2 = 7.5 , \textm ). Yes.
[ M_\textresisting = W \times 7.5 = 7.063 \times 7.5 = 52.97 , \textMN·m ]
Factor of safety against overturning:
[
\textFS = \fracM_\textresistingM_\textoverturning = \frac52.9713.08 \approx 4.05
]
Since ( 4.05 > 2 ), the dam is safe against overturning.
Answer:
(a) 1.962 MN, (b) 13.08 MN·m, (c) 4.05.
