Abstract:

The data reduction equations used to calculate the production quantities associated with pipeline and hopper dredges contain variables that introduce error into the final production calculation. These variables include not only the measurements made by the instrumentation, but also those associated with the dredging environment such as the density of the water and dredged sediments. The error due to one variable may be insignificant, but the propagation of the error through a data reduction equation with multiple variables may result in excessive uncertainty or error in the final result. This technical note will present an analytical method for determining the influence of each variable in the production equation on the total error resulting from the production calculation. Equations defining both solids and in situ volumetric production will he introduced. A mathematical method for determining the percent error or uncertainty of production calculations using these equations will be discussed and applied to example dredging problems.
