Inappropriate combination? Bridge, Water and a bad 3D mesh

Hello everyone,

i know that water can cause big problems in photogrammetry - but maybe someone has a good tip for me.
In my project (bridge over water reservoir) is the calculated point cloud of the structure work very blurry- probably because of reflections.

I have set the calculating area above sea-level and edited the point cloud in the ray cloud and turned some areas as “disabled”.
The problems:

  1. The edges of the bridge are very blurry and there are no clear borders in the orthophoto.
  2. In the 3D-Mesh are the bridge pillars disappearing (photo), which is an no-go for the model.

Has anyone a good workflow for modelling bridges (over water)?
