	The Water Module 2026 has several changes, most changes only make it faster or contain additional functionality. The changes listed below could also influence the outcome (by making it more realistic).		The Water Module 2026 has several changes, most changes only make it faster or contain additional functionality. The changes listed below could also influence the outcome (by making it more realistic).

	* '''[[~~Rasterization model\|~~Rasterization]]''': is now much faster and more accurate by using the 'center point'. The old 'outline' method could overshoot rasterize more cells that needed, this has been fixed by using center points. This can result in e.g. small differences in the way water flows between e.g. buildings.		* '''[[Rasterization]]''': is now much faster and more accurate by using the 'center point'.

	* '''[[Drainage (Water Overlay)\|Drainage height]]''': is not always set to the datum height provided, cells that are above the surface are now ignored. This creates easier drainage usage because in the old method the drain could be lowered due to 1 cell with a to low surface level.		* '''[[Drainage (Water Overlay)\|Drainage height]]''': is not always set to the datum height provided, cells that are above the surface are now ignored.
