Industrial runoff (Indicator)

General

The industrial runoff indicator calculates how much industry is near water. This allows some insight into the risk of water being contaminated by industrial processes due to their proximity to water bodies. This insight into the industrial runoff potential is useful when dealing with use-cases concerning:

• Spatial quality of life
• Biodiversity and nature
• Pollution and waste

This Excel indicator can be downloaded from the Tygron Index.

Indicator panel

The industrial runoff indicator.

The indicator panel shows the following information:

• The amount of industry in a neighborhood
• The amount of water in a neighborhood
• The amount of industry which is near water in that neighborhood. (Including industry which is in another neighborhood.)

Calculation

The indicator will calculate per neighborhood the amount of water with industry nearby. This can also be industry in another neighborhood but close to the water of the neighborhood in question.

The indicator performs the following calculation

• Determine amount of water in the neighborhood
• Determine the lotsize of industry-type constructions within 20 meters of the neighborhood's water
• Determine the ratio of water and the amount of industry found within 20 meters of the neighborhood's water
• Scale the resulting ratio to a range of 0% to 10%.
• Invert the ratio to compute the score (a lower ratio is a better score).

Score

The total score is determined by the ratio of industry near water over the total amount of water. The lower the ratio, the better.

For legibility, when used with absolute score, a ratio of 1:10 equals a score of 0%.

Additional configurations

The indicator can also be loaded in as a panel. When opened, it will highlight the locations where industry is close to the water.

The indicator will automatically support Dutch and English, based on the project's language settings.
