Climate change is severely stressing the existing hydraulic structures serving urban drainage systems. The “hydraulic” failure of sewer manholes, such as inlets, bends, drops, junctions or inline structures, is occurring more and more frequently because their capacity is exceeded by the flow discharges carried out during intense rainfall events. Beside physical models, the employment of CFD models may provide important guidelines for a novel hydraulic design of either new structures or to enhance the performance of existing structures. By this approach, hydraulic engineers benefit from an ample series of flow field data, as flow depths, water velocities and flow pressures, which are indispensable to guide towards an effective hydraulic and structural project. Capabilities, but also limits, of CFD modelling to simulate flow phenomena inside sewer hydraulic structures need to be deeply examined.

In the present days, the most common approach to finalize the development of innovative hydraulic structure configurations as well as the inspection of geometrical variations of existing structures consists in the CFD modelling. This tool is, indeed, often preferred to the classic physical modelling thanks to its sustainable cost and time requirements. The large potentiality of CFD models should be, however, managed with caution because, if erroneously used, it risks to conduct the designer to results which are quite far from  the real physics of the modelled phenomenon. The current bibliography about the numerical modelling of sewer structures needs undoubtedly to be enriched, giving the possibility to CFD model users to employ valid indications about, for example, the grid size, the boundary and initial conditions, the turbulence model and the required simulation time. All these modelling features, on one side, are strictly connected to the specific hydraulic structure to be analysed and, on the other side, influence the outcomes of the CFD investigation massively.

This Article Collection concerns the CFD-based studies of the flow features of hydraulic structures installed across urban drainage systems. The potential subtopics range from the description of the effects of various design parameters on the structural/hydraulic performance to the launch of innovative structures or the presentation of modified configurations of standard sewer appurtenances, based on the exploitation of CFD models. Further attention is also given to the papers reporting the relationship between physical and CFD modelling or describing successful techniques for controlling the accuracy and the stability of the modelling process. Original Research and Review Articles describing real case-studies are warmly welcomed.
