Answer 1

See Leonel Togniolli's "Water Effects" at efg's lab.

The ripple effect is based on 2D Water Effects in December 1999 Game Developer Magazine Article .

The algorithm is described in here 2D Water, as mentioned by François and as a reference in the source code.

Leonel's implementation is partly based on the gamedev article the-water-effect-explained by Roy Willemse. Here is also pascal code.

There is one more Delphi example at efg's called "Ripple Project", a screen shot is shown below.
