The Waterwijzer Overlay communicates with the [https://waterwijzerlandbouw.wur.nl/query-wdb.php?f=JSON Waterwijzer API] to calculate the loss of earnings for agriculture crops based on the following parameters:
The Waterwijzer module calculates the result for the following question:
* A climate scenario;
''I want to know the expected agricultural yield loss based on the crop, soil type and local groundwater levels, given a climate scenario and the expected weather.''
* A weather station;
* Type of soil;
* Type of crop;
* Highest and lowest (averaged) ground water levels;
* The irrigation parameter, which in the [https://waterwijzerlandbouw.wur.nl/tool.html Waterwijzer tool] is active for a number of the crop types, is currently not taken into account.


==Concept==
In order to answer this question using the {{software}} a connection (using API) was realized with Wageningen University's [https://waterwijzerlandbouw.wur.nl/ Waterwijzer Landbouw module].
Preparation steps:
#Generate a project for an area in the Netherlands using the {{software}}.
#*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.
#Add a [[Waterwijzer Overlay]]
#The climate scenario and weather station are configured using the Waterwijzer Overlay Wizard
#The ground water levels can also be configured using the Waterwijzer Overlay Wizard. These ground water levels can be provided as:
#* A [[GeoTiff|geotiff]] containing ground water depths;
#* A result type of the [[Subsidence Overlay]]; See [[Hi_ground_water_result_type_(Subsidence_Overlay)|high]] and [[Low_ground_water_result_type_(Subsidence_Overlay)|low ground water depths]].
#* A result type of the [[Groundwater_(Overlay)|Groundwater Overlay]]; See [[Ground_last_value_result_type_(Water_Overlay)|last ground water depth]] and [[Ground_max_value_result_type_(Water_Overlay)|max depth]]

The Waterwijzer Overlay is a [[Grid Overlay]]. The project area is rasterized into grid cells, each containing a value for:
|seealso=
* the type of crop, identified by their [[Brp code (Waterwijzer Overlay)|BRP Code]].
* [[Waterwijzer Overlay]]
* the soil: [[BOFEK_ID]]
|videos=
* the lowest (average) ground water depth: distance to surface, from geotiff or result overlay.

* the highest (average) ground water depth: distance of surface, from geotiff or result overlay.

The climate scenario and weather station are a single value for each grid cell.

Each unique combination of crop, soil, ground water depths, climate scenario and weather station leads to four loss of earning values, one for each category.

These categories are:
}}
* [[Damage_dry_result_type_(Waterwijzer Overlay)|Dry]]: A low water level (high ground water depth) can limit the amount of water absorbed by plant roots.
{{Template:Waterwijzer Module buttons}}
* [[Damage_wet_result_type_(Waterwijzer Overlay)|Wet/Oxygen]]: A high water level (low ground water depth) can lead to suffocation of the plant roots.
* [[Damage_indirect_result_type_(Waterwijzer Overlay)|Indirect]]: Indirect causes due to soil type in combination with crop, water levels, climate scenario and weather station's weather patterns.
* [[Damage_salt_result_type_(Waterwijzer Overlay)|Salt]]: The damage occurring due to irrigation with salt water.
These four categories are also summed up to a total number, resulting in a [[Damage_total_result_type_(Waterwijzer Overlay)|fifth result type]].

The Waterwijzer module calculates the result for the following question:

I want to know the expected agricultural yield loss based on the crop, soil type and local groundwater levels, given a climate scenario and the expected weather.

In order to answer this question using the Tygron Platform a connection (using API) was realized with Wageningen University's Waterwijzer Landbouw module.
