How do you compute dredge volume using bathymetric survey?

Volume computation is based on following:

  • Pre dredge survey bathymetric data (reference)
  • Post dredge survey bathymetric data
  • Channel design ( to calculate Cut and Fill)

Once you have all the prerequisite data, you can use and hydrography processing software for comparing pro and post survey data to determine volume dredged or need to be dredged.
