Network representation in hydrological modelling on urban catchments in data-scarce contexts: A case study on the Oued Fez catchment (Morocco)

Abstract Study region Oued Fez, Morocco. focus Urban catchments are heterogeneous in terms of land use and have both natural artificial drainage networks. Modelling them is not a straightforward task especially data-scarce settings. This study investigates network representation hydrological modelling using field data collected between 2008 2018 on the Fez catchment. The road used as proxy for stormwater network. Two production functions, SCS (1972) linear reservoir, coupled to lag route transfer function. Three types classes used. Tests carried out at hourly 5-minute time steps modified New insights Fifty-three rainfall–runoff events monitored urban part catchment over 2008–2018 period. highest rainfall values recorded 2008/2009, while peak flow 2017/2018. due stream channelisation increased coverage. Using with minimal improves model performance steps.
