Water quality modelling (Contact: Peter Steen Mikkelsen)
Dynamic models of water quality processes on urban surfaces and in sewers, wastewater treatment plants and receiving streams are developed in collaboration with external partners for use in practice as well as teaching and research. Perspectives currently pursued are development of an integrated simulation platform for use in e-learning, that allow simulating transport and fate of priority substances listed in the European Water Framework Directive, and development of source flux-fate models by linking fate models with geographical information systems used to characterize the pollution generating processes in the catchments.
Infiltration and groundwater interactions (Contact: Peter Steen Mikkelsen and Philip Binning)
Infiltration from small-scale stormwater management structures (i.e. infiltration trenches) is monitored and modelled to investigate the functional behaviour and potential clogging of such units. Modelling is also undertaken to couple stormwater models with groundwater models and integrated hydrological models, aiming at simulating the whole urban water cycle.
Model uncertainty and data fusion (Contact: Peter Steen Mikkelsen and Dan Rosbjerg)
Uncertainty in models of stochastic processes related to the rainfall and pollution runoff processes as well as impacts to the environment is investigated. Methods for on-line adaptation of model state variable predictions to actual measurements are furthermore investigated and applied to state-of-the-art simulation models. Input and parameter uncertainty as well as model structural uncertainty is addressed, and efforts are made to uncover how these influence risk estimates.
Warning and control (Contact: Jens Jørgen Linde and Peter Steen Mikkelsen)
A particular new focus if coupling of simulation models with spatial high-resolution rainfall data from X-band radars. The perspective is to unveil how radar data can improve forecasting of e.g. pluvial flooding incidents, combined sewer overflows and increased inflow to treatment plants, thus increasing the possibilities for optimising upstream storage utilization as well as downstream treatment processes through real time control.
