Waterwijzer Module test results

This article is a stub.

Testing the Waterwijzer Module manually is feasible, as the performed calculations are not spatial. This means for any given location, only the parameters present in that particular location are used to perform a calculation.

Setting up the project

• Create a new empty Project with a minimal size. By creating an empty project the state of the 3D world is entirely known.
• Add the Waterwijzer Overlay to the Project. This will perform the actual calculations.

Demarkation

A grid demarkation using the "concrete" Terrain Type.

Input for the Waterwijzer Module is determined through a number of visible and a number of invisible features. To make it easier to maintain an overview of what parameters are configured where, its recommended to add a number of visible features to the 3D world to demark the extend of specific configurations.

Using a distinctive Terrain Type such as "Concrete", draw a grid of plots. Make each plot approximately 20m by 20m. This should easily allow a grid of 10 by 10 plots.

Groundwater

A computed high groundwater result from the Subsidence Overlay. A computed low groundwater result shown in the minimap.

The groundwater situation is easiest to set up by using a Subsidence Overlay. It needn't calculate, but can have its groundwater situation directly configured through Areas and Attributes so that it's set to a specific value.

Across the "rows" of the grid currently drawn-in, the low groundwater result will vary. Across the "columns" of the grid, the high groundwater result will vary.

• In the 3D world, create and draw an Area across all columns for the first 2 rows. The Area will cover about 20 plots. Draw another Area across all columns for the next two rows, and repeat this until all plots are covered.
• Repeat this across all columns as well. The result should be a "checkerboard" of overlapping areas.
• Give all "row" Areas a GLG Attribute. For the first row, set it to 0,5. For the second row, set it to 0,6. For the third row 0,7 , the fourth row 0,8 , and the fifth row 0,9.
• Give all "column" Areas a GHG Attribute. For the first row, set it to 0,1. For the second row, set it to 0,2. For the third row 0,3 , the fourth row 0,4 , and the fifth row 0,5.
• Add a Subsidence Overlay
• Configure the Subsidence Overlay to not use GeoTiffs, defaulting it to determining groundwater levels through Area Attributes.
• Ensure the Subsidence Overlay outputs both a high groundwater result and a low groundwater result.

The 3D world is now divided up into a 5 by 5 grid of similar blocks, each consisting of 4 plots 20m by 20m. The blocks differ in combination of low and high groundwater level.

Terrains

A repeated pattern for the underground, 4 Terrain Types for every combination of groundwater.

Terrains, specifically underground Terrain Types, all have a specific BOFEK_ID. Multiple can be added to the 3D world to experiment with.

• For each block with plots with the same lowest groundwater and the same highest groundwater levels, draw the following Terrain Types in the following plots:
  • In the north-west plot, draw the underground to be "Koopveengronden op bosveen (of eutroof broekveen)", which has BOFEK_ID 101.
  • In the north-east plot, draw the underground to be "Veldpodzolgronden; grof zand", which has BOFEK_ID 320.
  • In the south-west plot, draw the underground to be "Moerige eerdgronden met een moerige bovengrond op zand", which has BOFEK_ID 203.
  • In the south-east plot, draw the underground to be "Kalkarme leek-/woudeerdgronden; klei, profielverloop 5", which has BOFEK_ID 415.
• Add an Underground Overlay, to review the configuration of the underground Terrain Types.

There is now a matrix of varying lowest groundwater levels, highest groundwater levels, and underground types.

Crops

Crops have a BRP Code as an Attribute assigned to them as part of the process of creating a new Project. New crops created through the Editor do not yet have a default code assigned to them, so regardless of the desired crops to test with, a code must be entered manually.

• Add a new Construction to the Project.
• Add a BRP_CODE Attribute to the Construction, with a value of "2014".
• Draw the Construction in the 3D world, so that it covers all the plots. Note that this doesn't need to be exact; it's just important that all plots are covered.
• Set the Function of the Construction to an agrarian type. Note that this is for visuals only, as only its BRP Code Attribute is used for the Waterwijzer Overlay.
