First, make your elevation taper off gradually under the waterline for a better look. Download Wakedit  and follow the directions included. Might I suggest making three parallel waypoint paths spaced close together for a better wave look. Basically, you name the first waypoint CoastStart1 and the last one CoastEnd1 then do the same for any other wave lines numbering each one. Then dump the map to file, which you'll find in the program side of the game. Open with Wakedit and pick the wave style. Save as the name of your map "Name.wak" inside your map folder.

Here's a shot from my mission map I'm working on showing multiple waves.

The readme text file explains what you need to do.

1)Make a waypoint path along your coast line. Replace the waypoint name on the first waypoint with CoastStart1. For the last waypoint on the path, again replace the name this time using CoastEnd1.

If you are making more than one wave line, repeat naming each line or path a new number, i.e. CoastStart2, CoastEnd2.

2)Dump Map To File. This is found under File. Note if you have already dumped this map once before, remove the older copy.

3)Open Wakedit and click the import button. Browse to find your map file.
C/Program Files/EA Games/Command & Conquer Generals Zero Hour/Your Map Name

4)If you've correctly named the waypoints (CoastStart#) Each coast line will come up where you pick the style and direction. Try Ocean and pick the direction. Note the direction can be tricky. If waves are going the wrong way, delete the file you save to your map folder and repeat this step again.

5)Save As (your map name.wak) Note: As I recall, It tried to save the file with .map extension. It should be with the .wak extension.

Also note that you need to be playing above the minimal graphic setting to see waves.
