Challenge Problems
Push your limits with advanced challenges
A soil sample has an elevation head of 3 m and pressure head of 1.5 m. Calculate the total head. If the soil's permeability is 5 cm/s and the hydraulic gradient is 0.1, what is the flow velocity?
💡 Hint: Calculate total head first, then apply Darcy’s law for flow velocity.
If a point in a soil body has a pressure head of 2 m, and the elevation head is 4 m, how does this influence the total head and subsequent water flow when comparing two different soil types with varying permeabilities?
💡 Hint: Think about how total head conditions would influence water movement through soil.
