The watershed module determines which waterways raindrops flow into, based on their starting locations and the terrain elevation.
Our watershed algorithm is used for identifying the watershed areas for predefined waterways. More generally, one is interested into which waterway a set of rain drops will end up based on the terrain elevation and the starting location of the drops.  
The locations of the drops that all end up in the same waterway can be grouped together to form a region called the '''watershed'''.  


Since we support the calculation of rainfall using our water module and can generate water flow direction results, we have altered the watershed algorithm to use the flow direction instead of the terrain elevation as input. Given that the rainfall used is adequately large, it helps us reducing the amount of local minima and hopefully generate more realistic results based on rainfall simulation.
===Watersheds applications===
Watersheds can be used for the following:
* For example to show which waterways are the largest and therefore most important in the water system to better manage maintenance and adjustments.
* Resolve disputes regarding the presence or absence of rainfall discharge on specific land parcels..
* Watersheds and their associated waterways can be used in external models to quantify rainfall for large-scale, low-detail systems.
* A client has to solve disputes with landowners complaining about (the lack of) rainfall discharge on their land.

Watershed overlay showing the calculated watersheds for a rural area. Each watershed is colored uniquely.

The watershed module determines which waterways raindrops flow into, based on their starting locations and the terrain elevation. The locations of the drops that all end up in the same waterway can be grouped together to form a region called the watershed.

Watersheds applications

Watersheds can be used for the following:

  • For example to show which waterways are the largest and therefore most important in the water system to better manage maintenance and adjustments.
  • Resolve disputes regarding the presence or absence of rainfall discharge on specific land parcels..
  • Watersheds and their associated waterways can be used in external models to quantify rainfall for large-scale, low-detail systems.
  • A client has to solve disputes with landowners complaining about (the lack of) rainfall discharge on their land.
