Question
Seepage is occurring through a porous media shown in the figure. The hydraulic conductivity values () are in m/day.
The seepage discharge (/day per m) through the porous media at section PQ is
Correct answer
(B) (1)/(2)
Solution
To find the seepage discharge (), we use Darcy's law for series flow through stratified soil.1. Identify given parameters:
- Upstream water head () = m
- Downstream water head () = m
- Total head loss () = m
- Thickness of the porous media () = m
- Width of the flow () = m (per meter length)
- Cross-sectional area () =
- m, m/day
- m, m/day
- m, m/day
