Joint project in cooperation with the City of Braunschweig (Department of Environmental Protection) and the working groups Environmental Systems Analysis & Landscape Ecology, Soil Science & Soil Physics of the Institute of Geoecology (TU Braunschweig) and the Institute for Sustainable Urbanism (TU Braunschweig).
The aim of the COABS project is to analyse climate risks in Braunschweig, develop measures to increase adaptive capacity and initiate their implementation. The end result is the development of building blocks for a city-wide adaptation strategy as well as adaptation measures in the fields of action "water quantity management & soil balance", "people & health" and "nature conservation & biodiversity".

This project is being carried out jointly with the Federal Environment Agency's Division II 3.1 "Drinking Water Resources" and 7 other partners. The topic of the overall project is the decentralized reuse of domestic wastewater for irrigation.
Climate change forecasts predict increased acute regional water shortages. This will intensify competition for water, for example between the use of fresh water as drinking water or as irrigation water. In regions that are seasonally affected by drought, reuse of treated wastewater can reduce this competition for use.
The on-demand treatment and disinfection of wastewater directly at the point of reuse ("Point-of-Use Reuse": PU2R) represents a promising supplement for irrigation in agricultural regions that are not directly connected to wastewater treatment plants. However, the treated water contains organic and inorganic pollutants that may pose a risk to groundwater or crops. To minimize risks, the prediction of contaminant dynamics in soils under wastewater irrigation is necessary.
The aim of our subproject is to develop a corresponding digital tool. For this purpose, suitable batch, laboratory column and lysimeter experiments with soils and treated wastewater will be performed. Subsequently, inverse simulation will be used to identify the most important reaction and transport processes and to estimate the process parameters with their uncertainties for process modeling.
