RE:PEAT
RE:PEAT is a project created by the Hoogheemraadschap De Stichtse Rijnlanden, who are a water authority in the Netherlands. The project is concerned with the problems surrounding subsidence in areas with significant peat soil, and the means to remedy or work around the problems surrounding it.
General information
The project is currently only available in Dutch. It has 2 levels.
Stakeholders
There are 4 stakeholder present in this project:
Municipality: The municipality is the government body who is concerned with the general care for the area, including but not limited to the livability for the residents, the viability of the agricultural sector, and the affordability of the maintenance of the local infrastructure.
Residents: The residents are the citizens in the area, who are concerned with the livability of the area. Their concerns are with their standards of living, and the costs associated with them.
Farmers: The farmers are the commercial/agricultural party concerned with revenue, but secondarily also with the quality of their land, both for their crops and the general livability.
Water authority: The water authority is the party in control of the water levels in the area, and with that the main tool for combating subsidence. However, they are also responsible for the costs associated with water management, and other hydrological aspects such as water safety and water quality.

Applying the template
Required data
To make use of this template, two GeoJSON files are expected:
"Percelen" file, for defining plots within an area with discrete data, in the form of "plots".
| Attribute | Description | Example | Remark |
|---|---|---|---|
| NAAM | The name of the plot. | PERCEEL: 1008 | |
| MVH_NAP | Height of the ground level, measured from Amsterdam Ordnance Datum (NAP). | 0.45 | |
| KLEIDEKM | The depth of the clay soil layer. | 0.45 | |
| GLG | The average lowest ground water level, in meters as measured from ground level. | 0.75 | This water level is used by the engine to calculate actual ground water levels, in combination with water level changes. |
| GHG | The average highest ground water level, in meters as measured from ground level. | 0.35 | This water level is used by the engine to calculate actual ground water levels, in combination with water level changes. |
| PEILGEB_N | The identification number of the level area which the plot belongs to. | 268 | |
| BODEM_N | The type of soil primarily present in the plot | 1 = peat, 2 = clay, 3 = clay on peat, 4 = sand | 3 |
| SUBSIDENCE | Whether this plot is subject to subsidence. | 1 | When this attribute is not present, subsidence is calculated. When this attribute is present and it's value is 0, subsidence is not calculated. When this attribute is present and it's value is not 0, subsidence is calculated. |
| PEIL_LAGER | The level area to which excess water is pumped off. | 268 | If this value is not present, water is presumed to be pumped out of the plan area. |
"Peilgebieden" file, for grouping plots together and setting of water levels, in the form of "level areas".
| Attribute | Description | Example | Remark |
|---|---|---|---|
| PEIL_NAAM | The name of the level area. | PEILGEBIED: PG0268 | |
| GEM_PEIL | The average water level in this level area, measured from Amsterdam Ordnance Datum (NAP). | -2.90 | |
| PEILGEB_N | The depth of the clay soil layer. | 0.45 | |
| URBANIZATION | How urban this level area is. Lower values are a more urban area. Higher values are a more rural area. | 3 |
Setting up a new project
Wizard
In the main menu, select the option "Start new project". Choose a name for the new project, and select the RE:PEAT template as the template to use. Select the area you wish to include in your project, and select "Generate Map". Depending on the size and complexity of the selected area, loading in an area may take some time.
