Simulation of the number of storm overflows considering changes in precipitation dynamics and the urbanisation of the catchment area: A probabilistic approach

“…To date, this aspect has not been addressed by researchers involved in the modelling of storm overflows. Based on the results of continuous measurements of precipitation and a calibrated hydrodynamic model for Innsbruck city, Jean et al (2019) analysed the possibility of determining precipitation characteristics for the design of an overflow. However, to a limited extent, these authors took into consideration aspects related to the identification of rainfall, which could have affected the final results of the calculations and problems with the interpretation of the resulting relationships.…”

“…The high compliance of the calculation results obtained using the probabilistic and hydrodynamic models indicates that the developed model constitutes a useful supporting tool when planning the directions of changes in the development of a catchment area (in a multiannual approach) in terms of reducing the number of storm overflows and therefore protecting water in streams. Due to the use of a simplified approach compared to that presented in previous papers (Kleidorfer et al, 2009;Thorndahl and Willems, 2008;Jean et al 2019), the approach used in this paper can be applied to analyses in everyday engineering practice as an alternative to complicated hydrodynamic models requiring a large amount of data. Moreover, the developed rainfall generator allows modelling of the dynamics of its changes in a long-term approach, which, compared to the currently used models (Gironás et al, 2010;Arnell, 2011;Arnbjerg-Nielsen et al, 2013), constitutes a considerable simplification.…”

“…Models constitute a useful tool when analysing the operations of sewage networks, but their construction requires a database containing the characteristics of the catchment area and the drainage network as well as measurements of precipitation and flows (with a high temporal resolution). Despite this, these models have a local nature; the cost of their preparation is high, and the results of model simulations do not always correspond to measured data (Elliott and Trowsdale, 2007;Thorndahl and Willems, 2008;Jean et al, 2019). However, access to universal tools that can be used for urban catchment areas with diverse physical-geographical characteristics without the need for model calibration is currently limited.…”
