Abstract Thermal stream loadings from both natural and anthropogenic sources have significant relevance with respect to ecosystem health water resources management, particularly in the context of future climate change. In recent years, there has been an increase field‐based research directed towards characterizing thermal energy transport exchange processes that occur at surface water/groundwater interface streams. spite this effort, relatively little work performed simulate these exchanges elucidate their roles mediating temperatures simultaneously take into account all pertinent hydrological, meteorological surface/variably‐saturated subsurface processes. To address issue, HydroGeoSphere, a fully‐integrated surface/subsurface flow model, was enhanced include fully integrated transport. HydroGeoSphere can flow, evapotranspiration, advective‐dispersive heat solute over 2D land 3D under variably saturated conditions. work, new capabilities are tested verified by comparing simulation results those previous groundwater injection study also simulating example atmospheric exchange. High‐resolution numerical simulations well‐characterized reach Pine River Ontario, Canada presented demonstrate atmosphere–groundwater–surface system. The successfully matched spatial variations patterns observed riverbed, groundwater. computational framework be used provide quantitative guidance establishing conditions needed maintain healthy ecosystem.
