Nature-based solutions (NBS) are increasingly promoted to mitigate urbanization effects, such as the urban heat island. The release of latent heat requires the availability of water in the urban soils. Models able to represent both detailed water and energy budgets are needed for a reliable evaluation of NBSs performances. The TEB-Hydro model is a recent hydro-microclimate model that extends the physics of the urban microclimate model TEB-Veg to water processes in urban subsoil in order to represent more realistically coupled water and energy budgets. Hence, the aim of this paper is to evaluate the TEB-Hydro model regarding how the water processes affect the energy balance. The model is applied to an urban French catchment for which both hydrological and microclimate data are continuously collected. The model shows general good performances in both simulating latent and sensible heat fluxes. Nevertheless, soil water contents are slightly underestimated during wet periods and overestimated during dry periods. Compared to the previous version of the model (TEB-Veg) with a simplified water budget, TEB-Hydro tends to more overestimate latent heat fluxes than TEB-Veg during dry periods. During wet periods, however, TEB-Hydro simulates better sensible heat fluxes and latent heat fluxes.

越来越多地推广基于自然的解决方案 (NBS)，以减轻城市化影响，例如城市热岛。潜热的释放需要城市土壤中的水。需要能够代表详细的水和能源预算的模型才能可靠地评估 NBS 的性能。TEB-Hydro 模型是最近的水微气候模型，它将城市微气候模型 TEB-Veg 的物理学扩展到城市底土中的水过程，以便更真实地表示耦合的水和能源预算。因此，本文的目的是评估关于水过程如何影响能量平衡的 TEB-Hydro 模型。该模型应用于连续收集水文和小气候数据的法国城市集水区。该模型在模拟潜热通量和显热通量方面均表现出良好的性能。然而，土壤含水量在湿润期略有低估，在旱期略高。与具有简化水预算的先前版本的模型 (TEB-Veg) 相比，TEB-Hydro 在干旱期间往往比 TEB-Veg 高估潜热通量。然而，在潮湿时期，TEB-Hydro 模拟了更好的感热通量和潜热通量。
