How much force in newton will be exerted by water waves on dam wall?

F = Pressure*Area

Thus, first, we need to find pressure exerted:

The pressure exerted by a water wave on a surface can be calculated using the dynamic pressure formula:

𝑃=1/2×𝜌×𝑉square

Where:

Therefore, pressure = 98000 Pa

Area of dam wall (abutment) = ~500msquare

Therefore, Force = 98000*500

                       = **49,000,000N**

These waves occur every 15secs, thus a force of 49,000,000N is exerted on the main dam wall or abutment every 15secs.
