TLDR
The comparison of the model results using the different typical design storm events from all the surrounding data points showed substantial differences for the assessment of the sewers regarding urban flooding, emphasizing the necessity of uncertainty analysis for hydrodynamic models.About:

Recent insights on uncertainties present in integrated catchment water quality modelling
Franz Tscheikner-Gratl,Vasilis Bellos,Alma Schellart,Antonio M. Moreno-Rodenas,Manoranjan Muthusamy,Jeroen Langeveld,Francois Clemens,Lorenzo Benedetti,Miguel A. Rico-Ramirez,Rita Carvalho,Lutz Breuer,James Shucksmith,Gerard B. M. Heuvelink,Simon Tait +13 more
TL;DR: This discussion attempts to address the question as to whether there is an increase in uncertainty by linking these models or if a compensation effect could take place and that overall uncertainty in key water quality parameters actually decreases.

Scalable flood level trend monitoring with surveillance cameras using a deep convolutional neural network
TL;DR: This work proposes a new approach that exploits existing surveillance camera systems to provide qualitative flood level trend information at scale and uses a deep convolutional neural network to detect floodwater in surveillance footage and a novel qualitative flood index as a proxy for water level fluctuations visible from a surveillance camera's viewpoint.

Event selection and two-stage approach for calibrating models of green urban drainage systems
TL;DR: In this article, 14 single-and two-stage strategies for selecting the calibration events were tested in calibration of a high and low-resolution Storm Water Management Model (SWMM) of a predominantly green urban area.

Automatic Calibration of the U.S. EPA SWMM Model for a Large Urban Catchment
TL;DR: In this article, the authors used GIS and stormwater model with a constrained optimization technique to estimate runoff parameters, and ten storms were used for calibration and validation, and the calibrated model predicted the observed outputs with reasonable accuracy.

TL;DR: It was found that SCEM-UA and AMALGAM produce results quicker than GLUE in terms of required number of simulations, but modellers should select the method which is most suitable for the system they are modelling, as GLUE requires the lowest modelling skills and is easy to implement.
