Identification of rainfall–runoff model for improved baseflow estimation in ungauged basins

Abstract Baseflow is an integral component of environmental flow prescriptions to mitigate the impacts of flow regime alteration on the ecological condition of rivers and often the most contentious issue in project planning, particularly for waterpower development. Baseflow prescriptions to meet ecological objectives are increasingly derived from a natural reference condition, often a simulated streamflow time series for an ungauged basin. …
