Losses of fill
Losses of Fill

Losses of fill can occur for several reasons and can result in not meeting the quantity of fill required for the dredging operation.

An Analytical Approach to the Sedimentation Process in Trailing Suction Hopper Dredgers
An Analytical Approach to the Sedimentation Process in Trailing Suction Hopper Dredgers

A number of theories are used (Camp, Groot, Miedema and Vlasblom, Yagi, Braaksma, Ooijens and van Rhee) to determine the overflow losses when loading trailing suction hopper dredgers. The model derived here has several important improvements, including the speed of doing the calculations.
