New developments
The water flow diagram is a tool that is constantly under development. The methodology is currently being extended by Eawag and the OST to include other aspects of water management. Detailed information on these projects can be found below.
Land use management in Brasil
When considering water management, the natural spatial boundary is the watershed, as it represents the boundary for natural processes. This has prompted us to extend the water flow diagram to the watershed level, taking into account natural seasonal fluctuations, land use management, and agricultural water bodies.
Find out how this is being implemented in Brazil here.
Sky to Sewer : Following Rainfall through the city
In Zurich, the basic WFD was extended with rainfall data. The extended version allows to track the rainfall along its path until it ends up in groundwater, surface water or back in the atmosphere after evapotranspiration.
Climate Resilience
As climate change resilience becomes more and more necessary, we aim at including this aspect in the WFD.
To that effect, a collaboration is ongoing in Nepal with the university of Kathmandu and the university of Bristol.
