Scholarcy highlights

  • While infiltration source-control technologies are increasingly used to manage the volume, rate and quality of stormwater runoff, there is little guidance on their role and impact on baseflow
  • This review addresses the impacts of urbanisation on baseflow in peri-urban catchments, with the aim to better understand the potential role of stormwater infiltration source-control technologies in restoring pre-development baseflows
  • We analyse the physiographic and anthropogenic factors that affect the baseflow response to urbanisation
  • We suggest that observed uncertainties in these baseflow responses may arise from inconsistencies in site assessment methodologies, including measurement techniques and selection of indicators
  • We conclude that source-control technologies have potential to mitigate the impact of urbanisation on baseflow hydrology, the complexity of subsurface flow processes makes it difficult to model the effects of the implementation of several stormwater management techniques on catchment baseflow
  • ► We review the impact of stormwater management on baseflow in peri-urban areas. ► Relevant techniques to assess and understand baseflow changes are not yet mainstream. ► Baseflow changes depend on both physiographic and urban development characteristics. ► The natural flow paradigm provides a framework to guide baseflow management. ► Source-control systems modelling will help understand their impacts on baseflow
