Thanks BobbM,

That is exactl what I needed. I really apprecate your intellect!

The ramp is 50 feet long. You could say the ramp starts at 0 degrees angle. I said one side was "one foot" just as a reference point. This is in a river not water with a tide to observe. There is arbitrary rise and fall from the dams being opened and closed but it would be very difficult to map and would not provide any data of value. I need to understand how to start the process from 0 degrees angle and how to convert or show the change in height of one end of the ramp and how much the ramp will shorten as the water rises, ideally in one foot increments. One end of the ramp is fixed and does not move. As the water rises, the other end of the ramp rises (changes angle) and the ramp effectively shortens. These are the main questions I am trying to answer. I have to make a chart that shows the change from 0 feet to 21 feet (the worst recorded flood). I hope this helps.
