Mass wasting is the rapid down-slope movement of rock and soil from a mountain or steep hill. If massive amounts of rock and soil land in a body of water, a tsunami can be the result.
Which of the following measures could help to reduce the negative effects of catastrophic mass-wasting events?

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.6 m below the tank bottom which is a = 6.7 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute). report your answer in meters to two decimal places.
