Dynamic modeling of urban hydrology in a geographic information system-setting with TFM-DYN

Summary, in English

The TFM-DYN model represents a significant advancement from static flow accumulation estimations into dynamic hydrological modeling (Nilsson et al., 2021). It incorporates variable precipitation in time and space as input together with high-resolution topography and includes functions for friction and infiltration to produce results such as water depths, flow velocity, inundated areas, flow pathways, and drainage areas for each point in the landscape. All water volumes in the simulation, whether moved, infiltrated, or input into the stormwater network, are recorded per time step and can be visualized in a geographic information system (GIS). All output data are saved in GIS layers, which can be visualized and managed in standard GIS software for further analyses. The versatility of this model extends beyond urban hydrological issues. Its application spans over a wide range of hydrological analyses in diverse landscapes.
