This Coastal and Hydraulics Engineering Technical Note (ERDC/CHL CHETN-IV-59) presents a statistical methodology for assessing the uncertainty of bathymetric analyses. The uncertainty assessment is based on the reported accuracy of a bathymetric survey. The US Army Corps of Engineers regularly conducts surveys to evaluate the navigability of waterways and to determine the pay quantity after a dredging project. The aerial extent and volume of subaqueous features can also be estimated from bathymetric data.
