What equation represents the wave speed in open channels?
💡 Hint: Remember how wave speed is defined based on depth and gravity.
True or False: A Froude number greater than 1 is associated with subcritical flow.
💡 Hint: Reflect on the definition of subcritical vs supercritical flow.

Challenge Problems
Push your limits with advanced challenges
A large water body experiences waves with speed 5 m/s in a depth of 3 m. Calculate gravity, and discuss how this gravity might affect aquatic life compared to Earth.
💡 Hint: Consider how gravity influences not just waves but overall ecosystem viability.
For a river 2 m deep flowing with a wave speed of 6 m/s, compute the minimum current speed to maintain downstream flow of waves without upstream movement. Discuss implications for building fisheries.
💡 Hint: Use the relationship founded in our wave dynamics discussion to guide your estimation.
