How does the seabed affect sonar?
Ok, we've collected a lot of resources on various aspects of naval warfare over the years, as I am sure you can imagine, but I can't find a good explanation of how to model how sonar affects detection near the seabed.

What's the best way to model the effect on detectability when the sub is near the seabed (the ocean is relatively shallow)? Conversely, how does this affect the sub's own active and passive sonar when it tries to detect surface targets? What if it is near an edge, where it gets deeper, or a steep, where it gets more shallow.

NWAC is not a sub sim per se, but these things should be modeled as accurately as possible (within reason).

Since this is such a knowledgeable forum, I'd like to have your feedback if possible.
