3Di includes a module for water quality calculations. Use the exact same model that was used for water quantity calculations also for water quality. It’s as simple as adding a point source in your schematisation, run the simulation and analyse how these substances spread through the water system.
The benefits of the 3Di Water Quality module:
- Quick and easy to set up
- Using the 3Di computational core ensures an accurate water balance, inflow and outflow of the fluxes in the study area
- Insight in the spatial distribution of substances
- Follow substances through all domains, e.g. surface water, sewerage system, groundwater
- Insight in the origin of water, e.g. rain, dwf, rain on a specific area
Model and predict the flow of contaminants
The animation shows how the pesticide moves through the surface water and drainage system. It visualizes the spread of contamination across different areas over time. This clear and dynamic animation demonstrates how our water quality module models and predicts the flow of contaminants both through surface water, overland flow and the drainage system, providing valuable insights for environmental monitoring and management.
How does it work?
This video showcases the functionality of our water quality module using a small scale integrated model of Langå in Denmark.
In this demonstration, we focus on the input parameters for the amount of pesticide introduced into the water system. We then present an animation that visualises the flow of the pesticide through the environment.
Simulate a sewer overflow simulation
On the left is an example of a sewer overflow simulation. The animation shows how the overflow water spreads through the water system. This information helps determine what measures, if any, are needed to maintain clean surface water now and in the future.
Include Dry Weather Flow in your simulation
On the right is an example of labelling. When labelling the Dry Weather Flow (DWF), it is possible to see the percentage of DWF on the street after a heavy rainfall event.
This information helps identify where and what measures are needed to prevent this occurrence.
Follow the substance through rivers and floodplains
On the left is an example of how a substance can disperse through the River Rhine. In this case, a small high-water wave moves through the river, allowing the substance to flow into the floodplains.
It is possible to assign the substance a decay factor and assess where in the river the official concentration threshold is exceeded.
How to use the 3Di water quality calculations in any situation
Water from a certain area can be labelled as a substance, allowing modellers direct insight in the origin of water in certain water bodies.
The applications are endless, a few examples:
- Follow sewerage overflow water in the surface water
- See impact of climate change, e.g. see the effect of different water quantities on the water quality
- Is flushing my system (sewerage or polder) effective?
The results of the 3Di Water Quality module are available in common file formats and can be used by water quality experts for more in-depth analysis
