Abstract: We present a methodology for the mathematical modeling of Nature-Based Solutions (NBS) in a catchment area in order to determine the reduction of the flood risk. The methodology is based on a literature survey that we performed to identify the main NBS that are being applied worldwide and the implemented hydrologic and hydrodynamic models that are usually 1D/2D. We describe briefly the 12 steps of the methodology. Two of the most important steps are (1) the effect of the Climate Change impacts via climate models or by simply considering what-if scenarios and (2) the simulation of NBS using well-known 1D/2D models after performing the required modifications in the geometrical characteristics, the distribution of Manning coefficients and the equations of hydraulic structures, such as weirs, based on computations using 3D hydrodynamic models.     «
