Abstract. Stream temperatures have been increasing worldwide, in some cases reaching unsustainable levels for aquatic life. Riparian revegetation has identified as a strategy managing stream by blocking direct solar radiation. In this study, the effects of riparian vegetation on were included within Soil & Water Assessment Tool (SWAT) model through shade factor parameter. An equilibrium temperature approach was used to integrate an energy balance context. The sub-model improved using new equation and integrated into SWAT. Unlike existing models, modified SWAT enables representation two processes – mass heat transfer that influence change simulation shading its at sub-basin scales. updated tested Dairy McKay Watershed, OR, USA, four scenarios: current conditions vegetation, full restoration, efficient no vegetation. calibration under showed good performance (Nash–Sutcliffe efficiency NSE > 0.74). reduction number days with above survival limits (NDSTASL) species also evaluated measures performance. Findings average reductions 0.91 ∘C (SD = 0.69 ∘C) NDSTASL 17.1 d over year restoration 0.86 = 0.67
