Waterwijzer Module

Considerations

The Waterwijzer Overlay communicates with the Waterwijzer API to calculate the loss of earnings for agriculture crops based on the following parameters:

• A climate scenario;
• A weather station;
• Type of soil;
• Type of crop;
• Highest and lowest (averaged) ground water levels;
• The irrigation parameter, which in the Waterwijzer tool is active for a number of the crop types, is currently not taken into account.

Concept

Preliminaries:

1. Generate a project for an area in the Netherlands using the Tygron Platform.
   • The Dutch BRP geo-plugin retrieves the known agriculture plots. Each agriculture plot has an identification number for the type of plot, which is stored in the BRP_CODE attribute.
   • The Dutch BRO geo-plugin retrieves the known soil types, stored as underground terrain. The simplified BOFEK_ID is configured by default for each terrain type of these terrain.
2. The climate scenario and weather station are configured using the Waterwijzer Overlay Wizard
3. The ground water levels can also be configured using the Waterwijzer Overlay Wizard. These ground water levels can be provided as:
   • A geotiff containing ground water depths;
   • A result type of the Subsidence Overlay; See high and low ground water depths.
   • A result type of the Groundwater Overlay; See last ground water depth and max depth
