help with a device to live safely with water?

Question

i need to design a product that will stabilize shorelines and reduce
the erosion effects of wave action. build a working model of your erosion control, in this i must onclude water with waves striking the shore at differnt angles. the model must visibly demonstrate wave actions. i do know how to make the actual model but, how would i make the machine that makes the waves? ive seen it on bill nye but i forget what eppisode that it is on....

and i have to use actual water.... so i need to know how to make a machine that will make waves that go in different directions....no plastic rap?

Answer 1

Wave machines involve pushing either a flap, hinged at the bottom, or a wall, mounted so it can stay vertical while moving laterally, into the water in your wave tank and back to the edge again. Occasionally a plate is pushed vertically into the water. Small ones are driven with cams off electric motors, larger ones can use hydraulic or air pistons. It is usually the most complicated and expensive part of the tank. Researchers normally move the model, rather than the wave machine, to get different angles. Google "wave tank" to see various designs, including student and virtual ones.

Answer 2

Several ways . One make a paddel, two make a bubble in plastic
