Nourishment is an adaptation technology primarily used in response to shoreline erosion and flood reduction. It is a soft engineering approach to coastal protection which involves the artificial addition of sediment to an area that has a sediment deficit. Normally the effect of nourishment needs to be modeled with a numerical model including sediment transport and morphology, however, in Delft Dashboard it is also possible to analyse the effects of a nourishment with the Nourishment toolbox.

- Create a model domain by clicking on 'Draw Outline' with a certain spacing (i.e. grid size)
- Define a polygon where you would like to model a nourishment
- Define how much sand you would like to deposit (i.e. certain volume, thickness, etc.)
- Click on 'Compute' to calculate the effect.
The effect are is strongly related to the currents you apply. It is possible to apply the same current in U and V in the entire domain or to apply a spatially varying current.
