Abstract
- The transport of materials and energy between rivers and riparian zones are driven by lateral hyporheic exchange and plays a vital role in regulating the ecological health of rivers. Owing to the limitations of models and methods, prior research has mainly focused on vertical hyporheic exchange in river systems. Combined with the collected riparian zone temperature and water level data, a 2D hydrothermal coupling model of the riparian zone was developed using the thermal conductivity model, and the fitting effects of the Lu et al. (2007) model and Su et al. (2016) model on temperature variations in riparian zone comparatively analyzed. Then, the dynamic variation characteristics of the riparian zone temperature and the lateral hyporheic exchange recharge pattern were investigated by the constructed models. The calibrated model could reasonably illustrate the variations in the riparian zone temperature, and the sensitivity analysis revealed that the hydraulic conductivity (Ks) is the most sensitive factor to the temperature variations.
