I think it would be best (easiest) to draw special delta tiles, one for each 
combination of rivers/oceans (feel free to do so).

LRL  LRL  LRL and so on.

The client could also be told to draw tiles that are in the corner between 
river and ocean specially.

I have plans for a whole new map generator with climate calculations (altitude, 
wind, precipitation, evaporation, latitude, biomes, ...). It would then of 
course also support differnt river sizes. Maybe even corrosion and 
sedimentation (delta).

But that is really long term. I haven't even decided which coordinate 
system/view/projection to use yet. But if you paint it I will design the 
simulation algorithms, OK?

By the way, does anyone know how to visualize heights on the map, like in Alpha 
Centauri? I will need to know this before I can start.

Such a map generator could be used by many more games than Freeciv, even real 
time games.
