The possible impacts of a climatic change associated with an increase in CO2 on the hydrology of forests is evaluated by applying sensitivity analysis and a climatic scenario to a one-dimensional model. Water consumption of forests is affected by changes in plant physiology and meteorological environment. Changes in species composition are not taken into account. Increase in CO2 leads to a decrease of stomatal conductance, resulting in a decrease in transpiration of 10-30%. The evaporation of rainfall interception by the canopy is increased due to a higher leaf area index and higher temperatures. Application of a wet scenario shows an increase in total interception, but the ratio between interception and precipitation decreases. Simulating [...]
