I’m not sure what you mean by “structures,” but in general yes. The only thing that destroys calibration is moving the projector with respect to the camera, even by very little. Any time you do that you need to recalibrate. What you do to the sand won’t affect it.

If you put any objects on top of or into the sand, such as Lego bricks or model trains, they will typically get picked up by the Kinect, and the software will interpret them as part of the sand surface (the software can’t distinguish sand from non-sand). So they will get integrated into the topography, the projector will colorize them based on their height and put contour lines onto them, and water will flow around them.
