Can this be calculated or do I need to add something?

Given a barge with a draft ( less than 6") **This is constant.**

First scenario:

If the CURRENT is 2 mph

The (surface)SPEED is 4 mph

The RAMP is lowered to an **ANGLE **of 20°

The RAMP is 20' long x 72" wide aluminum **( constant)**

What would be the force in pounds per sq/ft exerted on the ramp? ( average, close estimate,)

Second scenario:

Everything remains the same except the **RAMP's ANGLE is now 30º.**

What would be the force in pounds per sq/ft on the ramp's surface?
