Hydrodynamic modelling of urban areas: analysis of key features and development of a new, anisotropic artificial porosity, sub-grid model

Hydrodynamic modelling of urban areas. In the first part the presence of high-resolution features inside an urban area are tested in order to highlight the possible variations. In the second part different sub-grid models for urban area are tested and in particular is created and tested a new subgrid model with an anisotropic artificial porosity
