NESTOR - modeling dredging operations in the river bed
NESTOR coupled with the morphodynamic module SISYPHE offers the possibility of using documented data from dredging operations to model the resulting changes in the bottom level. Thus the period of time, the volume of sediment removed during that period of time and the size and location of the dredging site can be defined. This data can subsequently be used to determine the resulting bottom level for that site.

A second possibility of initiating dredging was incorporated in NESTOR for forecasting purposes. The objective was for dredging to be carried out automatically whenever too much sediment is deposited in the navigable areas of bodies of water.
