Retention Basin - terrestrial Photogrammetry and Volume calculation

After heavy rainfalls and a mudflow, the retention basin above a settlement needs to be analysed regarding volume and deposit height. Using terrestrial RTK camera devices from @REDcatchGmbH and@agisoftmetashape3247 for multitemporal 3D reconstruction. Analysis were performed in CloudCompare.
