Computer-Aided Modelling of Stormwater Systems deals with the construction of probabilistic models of rainfall and their use in the sizing of retention tanks. The book discusses methods of sensitivity and uncertainty analysis of hydrodynamic models of urban catchments, as well as proprietary calculation algorithms for the sizing of retention tanks, considering the uncertainty of calibrated parameters and the variability of outflow hydrographs from the catchment and shape parameters. This is important from the point of view of contemporary hydrology of urban catchments because it is the reliability of the identified parameters and their appropriate selection that determines the developed hydrodynamic model of the catchment, so that it finds a practical application in sewage network management. Also included are innovative graphical and analytical methods of tanks sizing, whereby the shapes of hydrographs of the outflow from the catchment area are considered, which is omitted in most of the methods used. Hybrid models which are a combination of graphical and analytical methods with probabilistic models of rainfall are also presented, which makes it possible to shorten the calculation time. Finally, the ability to implement computational algorithms in the field of sensitivity and uncertainty analysis can also be used when analysing catchments with implemented green infrastructure facilities.

Computer-Aided Modelling of Stormwater Systems is aimed at doctoral students, research workers and engineers as an introduction to modern methods of modelling stormwater and combined sewer networks together with the objects located on it, such as retention tanks.
