“…The most recent event occurred between 5 June and 4 August, 2011, registering a flow rate of up to 1539 m 3 /s, generating economic losses of more than 88 million dollars [58]. The May 2011 flood, as recorded at the Richelieu River at Rouses Point, was estimated to have a recurrence period equal to or greater than 1 in 500 years [59]. The starting point for the SA was the 2D finite element model H2D2 [60].…”

A new method for sensitivity analysis of water depths is presented based on a two-dimensional hydraulic model as a convenient and cost-effective alternative to Monte Carlo simulations. The method involves perturbation of the probability distribution of input variables. A relative sensitivity index is calculated for each variable, using the Gauss quadrature sampling, thus limiting the number of runs of the hydraulic model. The variable-related highest variation of the expected water depths is considered to be the most influential. The proposed method proved particularly efficient, requiring less information to describe model inputs and fewer model executions to calculate the sensitivity index. It was tested over a 45 km long reach of the Richelieu River, Canada. A 2D hydraulic model was used to solve the shallow water equations (SWE). Three input variables were considered: Flow rate, Manning’s coefficient, and topography of a shoal within the considered reach. Four flow scenarios were simulated with discharge rates of 759, 824, 936, and 1113 m 3 / s . The results show that the predicted water depths were most sensitive to the topography of the shoal, whereas the sensitivity indices of Manning’s coefficient and the flow rate were comparatively lower. These results are important for making better hydraulic models, taking into account the sensitivity analysis.

“…Land‐use alterations are particularly problematic downstream from lakes and reservoirs, where hydrologic alterations such as channelization and levee construction reduce the storm buffering capabilities of these waterbodies (McIntyre & Naney, 1990; Nystrom et al, 2018; Shankman & Liang, 2003). Flooding in these areas results in shoreline erosion and damage to property and crops and, in extreme cases, requires evacuation and relocation of the population (Ahmad et al, 2022; Bjerklie et al, 2014; Chen et al, 2019, 2022; Cummings et al, 2012; Shankman & Liang, 2003).…”

“…However, field surveying is tedious and costly in terms of large‐scale relevance (Chen et al, 2019). In response to the rising need for cost‐effective, accurate, and timely flood inundation assessment, methods using remote‐sensing technologies and hydrodynamic modeling are widely utilized (Bjerklie et al, 2014; Chen et al, 2022; Cummings et al, 2012).…”
