Modelling urban floods using a finite element staggered scheme with porosity and anisotropic resistance [PDF]
, 2018 Artificial porosity models for urban flooding use porosity as a statistical descriptor for the presence of buildings, which are then treated as subgridscale features. Computational efficiency makes porosity models attractive for large-scale applications.

The Assessment of Level of Flash Floods Threat of Urbanised Areas
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2017 Flash floods (or torrential rain flooding) is another type of flood hazard which has caused casualties and significant property damages. A methodology for identification of urban areas, which can potentially be burdened by that type of flood hazard, was ...
