Challenge Problems
Push your limits with advanced challenges
Create a flow net for an unconfined aquifer scenario where the top and bottom boundaries are constant hydraulic heads. Describe how you would determine the equipotential lines and flow lines.
💡 Hint: Consider the overall hydraulic gradient and how it affects your flow direction.
In a given area, the phreatic surface was found to be sloping towards a river. Analyze how this impacts the groundwater flowing in that direction and relate it to your flow net.
💡 Hint: Visualize how pressure changes when heading towards a lower area, such as the river.
