I'm trying to plot inundation at different elevations on a 3D ground surface elevation plot. The closest I have got so far has been to use FillingStyle as the following simple example shows:

ListPlot3D[Table[Sin[j^2 + i], {i, 0, Pi, 0.1}, {j, 0, Pi, 0.1}], Filling -> 0, FillingStyle -> {Blue, None}]

enter image description here

But I want the water to be shown only on the ground. In other words, I want the filling operation to be done only when the surface is lower than the filling plane (z=0 in this example). Any ideas how to do that?

Thanks in advance.

table = Table[Sin[j^2 + i], {i, 0, Pi, 0.1}, {j, 0, Pi, 0.1}];

 ListPlot3D[table, Filling -> 0, RegionFunction -> (#3 <= 0 &), FillingStyle -> Blue]]
