Urban hydrology simulation of a semi-urban catchment with multi-hydro comparing X-band and C-band radar data

The complexity of urban hydrology results both from that of urban systems and that of rainfall, especially their extreme variability across scales. This complexity is furthermore increasing with climate change potentially yielding stronger extremes according to IPCC, as well as with continued urban development. Cities should be increasingly incorporated not only into their hydrological basin, but also into their climatic evolution. This leads to an expansion of the spatial and temporal scales to be considered when analysing and simulating hydrological behaviour of urban areas. It should include the possible feedbacks within the water cycle at small scale, such as local extremes causing large scale effects and numerous numerical representation failures.
