| % loss of earnings
| The loss of agricultural earnings for drought scenarios, for a particular crop, using the highest and lowest ground water levels adjusted by subsidence. These earnings are calculated by the Waterwijzer Landbouw api. When the water levels in the ground are too low, roots are unable to absorb enough moisture.
|-

| % loss of earnings
| The loss of agricultural earnings due to high ground water levels, for a particular crop, using the highest and lowest ground water levels adjusted by subsidence. These earnings are calculated by the Waterwijzer Landbouw api. When the water levels in the ground are too high, subsurface air is replaced by water and plant roots cannot obtain enough oxygen.

| [[Damage_indirect_result_type_(Subsidence_Overlay)|DAMAGE_INDIRECT]]
| % loss of earnings
| The loss of agricultural earnings due to indirect causes, for a particular crop, using the highest and lowest ground water levels adjusted by subsidence. These earnings are calculated by the Waterwijzer Landbouw api. Indirect causes relate to the type of soil, type of crop and water levels.

| The loss of agricultural earnings due to salt water irrigation or salt water seepage, for a particular crop, using the highest and lowest ground water levels adjusted by subsidence. These earnings are calculated by the Waterwijzer Landbouw api. Too much salt concentration leads to a reduction of water absorption of plant roots, increased toxicity, problems with nutrients absorption and decreased root growth.

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.

Module

A Waterwijzer Overlay can be configured by opening the Waterwijzer Overlay Wizard. More in-depth information can be found under each of the categories below.
