The water purification assessment represents hydrological processes in Alberta watersheds. This includes the tracking of water and sediment movement across specific landscapes and delineation to water bodies such as rivers, streams, wetlands, or lakes. In part, the model was designed to identify source areas of pollutants, important areas for removing pollutants, and impacts to downstream water users.
The water purification assessment captures how precipitation, topography and landscape components affect overland flow and stream flow (the provision of the water purification but not water purification itself) . Overland flow is then connected to water quality variables (nitrogen, phosphorus and sediment) to look at how these variables are routed through the hydrological system including: where the nutrients and sediment came from, how they are moving through the system and where they end up. Physical conditions are necessary to support future predictions of this ecosystem service.
This ecosystem service assessment explores how a given landscape generates a level of water purification and how changes in landscape/land cover might affect it. Everything in the model is tied to land cover, so the user could create and test scenarios in terms of ecosystem service degradation/augmentation by changing land cover.
