Currently I’m working on a seaplane base in MSFS 2024. The banks of the body of water / at the docks are too shallow, which beaches the parked floatplanes. Is there a way to deepen the banks of the water?
It seems a couple of parked seaplanes on the satellite imagery were interpreted as a sandbank or elevation.
There is depth gradient to transition between terrain and water.
It cannot be modified but what you can do is move your water polygon a bit more inland so that the depth were the aircraft are parked is more important.
You will probably need to do the quay with mesh instead of using the terrain though.
