This review provides a synthesis of advances in our understanding of urban flood processes
and their modelling over the last four years (2018–2021). Four aspects are covered …

In the context of large-scale urban flood modeling, porosity shallow-water models enable a
considerable speed-up in computations while preserving information on subgrid …

Flood hazard mitigation in urban areas crossed by vegetated flows can be achieved through
two distinct approaches, based on structural and eco-friendly solutions, referred to as grey …

Water-sensitive urban design is an integral part of flood risk management. Based on
computational modelling, we investigated the influence of various urban forms on flooding …

In the framework of porosity models for large-scale urban floods, this work presents a
method to compute the spatial distribution of the porosity parameters of complex urban …

When modeling large-scale urban floods, the Porosity Nonlinear Shallow Water Equations
(PNSWE) emerge as an interesting and consistent subgrid approach to reduce …

A comparative study concerning dynamic, local, and zero inertia variants of volume-
averaged depth-integrated porous shallow water equations has been presented. The first …

The present study constructed a path-conservative high-order positivity-preserving well-
balanced finite volume Riemann solver for the one-dimensional porous shallow water …

Simulated free surface transients in periodic urban layouts have been reported to be self-
similar in the space-time domain when averaged on the scale of the building period. Such …

The use of classic two-dimensional (2D) shallow water equations (SWE) for flooding
simulation in complex urban environments is computationally expensive, due to the need of …
