Worldwide, the need for transformative change in urban water management is acknowledged by scientists and policy makers. The effects of climate change and developments such as urbanization, the European Water Framework Directive, and societal concerns about the sustainability of urban water system force the sector to adapt. In The Netherlands, a shift towards integration of spatial planning and water management can be observed. Despite major changes in water management policy and approach, changes in the physical urban water management infrastructure remain limited to incremental solutions and demonstration projects. Policy studies show that institutional factors and professional perceptions are important factors for application of innovations in urban water management. An online survey among Dutch urban water management professionals demonstrates that according to most respondents, optimization of the current system is sufficient to achieve both European and national objectives for sustainable urban water management. The respondents are most concerned with the effects of climate change on urban water systems. In contrast to current policy of the national government, priority factors that should be addressed to achieve a more sustainable urban water system are improving knowledge of local urban water systems, capacity building, developing trust between stakeholders, and improving involvement of elected officials and citizens.

Abstract Sedimentation devices have been widely implemented to remove suspended solids and attached pollutants from stormwater before entering surface waters. The treatment performance of these best management practices (BMPs) on fine particles is rarely investigated in a standardized way. To overcome this information gap a reliable and standardized testing procedure is formulated. Four devices have been tested on their suspended sediments removal efficiency at different discharges and particle sizes, using the newly developed standardized full scale test method. The observed removal rates of the facilities with a storage volume in the order of 1.5 m3 and settling surface around 1 m2 drop to low removal efficiencies at flow rates of 10 l/s or more. For small sized sediments (up to 63 μm) the removal efficiency is below 50%. The results of the experiments can be used to improve both the design and the dimensions of stormwater treatment devices.

Abstract Two ways of connecting numerical hydrological models that have significantly differently sized calculation time steps are compared. A model for rainfall–runoff and surface water flow (SOBEK) is connected to a model for groundwater flow (TRIWACO). Data exchange between the two models takes place at the end of each larger time step. In the “explicit” connection, both models calculate every time step only once, after which the algorithm moves to the next time step. In the “implicit” connection, the same time step is recalculated with the exchanged data until the resulting exchanged values converge. Due to the iteration, implicit connections require more calculation time, which can only be justified if it leads to significant improvements of model predictions. By simulating the hydrological situation of the Huewelerbach basin in Luxembourg, this work shows that implicit and explicit connections can indeed lead to significantly different calculation results.
