This functionality is currently unavailable or non-functional.

The waterwijzer overlay provides the yield loss of crops based on several input parameters. The yield loss is currently calculated by the Waterwijzer Landbouw module, which is described here.

Usage

The Waterwijzer Overlay results can be used to:

  • Calculate the yield loss based on existing crops for currently known highest and lowest groundwater levels.
  • Calculate the yield loss for crops when using different groundwater level management strategies simulated by a Groundwater Overlay or a Subsidence Overlay.
  • Determine the best type of crop per parcel given the highest and lowest groundwater levels and type of soil.

Considerations

The Waterwijzer Overlay calculates yield loss for agriculture crops based on:

Additionally:

  • The Overlay makes use specifically of version 2.0.0 of the Waterwijzer tool.
  • The irrigation parameter, which in the Waterwijzer tool is active for a number of the crop types, is currently not taken into account.

Result types

The overlay offers multiple result types. Each result type expresses the yield loss due to specific circumstances as a percentage.

Icon Result type Unit Mode Description
Overlay icon waterwijzer damage dry.png DAMAGE_DRY  % yield loss The loss of agricultural yield due to low groundwater levels.
Overlay icon waterwijzer damage wet.png DAMAGE_WET  % yield loss The loss of agricultural yield due to high groundwater levels.
Overlay icon waterwijzer damage indirect.png DAMAGE_INDIRECT  % yield loss The loss of agricultural yield due to indirect causes.
Overlay icon waterwijzer damage salt.png DAMAGE_SALT  % yield loss The loss of agricultural yield due to salt water irrigation or ground bottom flow with salt water.
Overlay icon subsidence damage total.png DAMAGE_TOTAL  % yield loss The total loss of agricultural yield for a particular crop.
