Fig. 10: Modelled daily irrigation water upkeep to maintain the trees at field capacity.
From: Impact of soil moisture content on urban tree evaporative cooling and human thermal comfort
Calculated by estimating the water quantity needed in order to match the water lost by tree transpiration and soil evaporation per unit area. Panels show LCZ ② (a), LCZ ⑤ (b) and LCZ ⑥ (c). At daily irrigation smaller than the Irr scenario boundaries (depicted in dashed lines for Avg. and Ext. scenarios), the soil would start to lose water and reach the behaviour of the ETmax scenario. If water input continues smaller than the boundaries, the conditions can go all the way down to the Dry scenario, not depicted here, but which are roughly similar to ETmax as seen in Fig. 6.
