For saline intrusion, we refer to several national-level and publicly available datasets. These datasets provide insights on the areas currently prone to salinisation via groundwater, including for different sea level rise scenarios and low river discharge. Please refer to the Assumptions & limitations page for more information about the datasets.

Location boundary between fresh and saline groundwater |
| Description |
The map shows the depths at which fresh groundwater is turning brackish. In other words: the location at which salinisation occurs. The map is based on a chloride concentration of 1,000 mg/l as the limit between fresh and saline. More information can be found on the Climate Impact Atlas map narrative. |

Salt load |
| Description |
This map shows the current salt load. This gives insight into the volume of salt flowing from the groundwater into the surface water throughout the Netherlands. More information can be found on the Climate Impact Atlas map narrative. |

Salt load difference sea level rise |
| Description |
This map shows the salt load difference due to sea level rise. This gives insight into the volume of salt flowing from the groundwater into the surface water due to sea level rise. More information can be found on the Climate Impact Atlas map narrative. |

Change in flushing water demand |
| Description |
This map shows the changes in polder flushing water requirements at rise in sea level of 0.5 metre, 1 metre, and 3 metres, even if the polder water is to be kept as fresh as it currently is. More information can be found on the Climate Impact Atlas map narrative. |

Salinisation of surface water via estuaries due to sea level rise and low discharge

|
| Description |
The maps show various combinations of sea level rise and low discharges in the river Rhine. The maps present the depth average and tidal average chloride concentrations. This indicates by how much surface water will salinify at various sea level rises (0.5, 1, 2 metres) at averagely low discharge volumes (2000, 1000, 500 m3/s).
