In this work, diurnal heating, by solar radiation, and cooling in a sloping water body with vegetated shallow regions are investigated numerically. The sloping water body consists of a vegetated region with a bottom slope equal to 0.1 and a deep region with a horizontal bottom. The Volume-Averaged Navier-Stokes equations together with the Volume-Averaged Energy equation are solved numerically in the vegetated region. The latter has porosity equal to 0.85 (typical of aquatic plants found in lakes) and a length equal to the total length of the sloping region. At the top free surface, a time-dependent thermal forcing is applied, which is reduced in the vegetated region. Shallow water is considered with a maximum water depth being less than the penetration depth of the solar radiation. The non-vegetated sloping water body is also considered for validation purposes. The results (isotherms, streamlines, exchange flow rate), after ten full thermal forcing cycles, indicate significant vegetation effects on the daytime and night circulation and the exchange flow rates.

在这项工作中，对太阳辐射的昼夜加热和具有植被浅层区域的倾斜水体的冷却进行了数值研究。倾斜水体由底部坡度等于0.1的植被区域和底部水平的深层区域组成。在植被区域中对体积平均纳维-斯托克斯方程和体积平均能量方程进行数值求解。后者的孔隙度等于 0.85（典型的湖泊中发现的水生植物），长度等于倾斜区域的总长度。在顶部自由表面，施加与时间相关的热力，该热力在植被区域中减小。浅水被认为是最大水深小于太阳辐射的穿透深度。无植被的倾斜水体也被考虑用于验证目的。经过十次完整的热强迫循环后的结果（等温线、流线、交换流量）表明植被对白天和夜间环流以及交换流量的显着影响。
