Annual and intra-annual water balance components of a short rotation poplar coppice based on sap flow and micrometeorological and hydrological approaches

Original language description

Comparative measurements of canopy transpiration (T) and evapotranspiration (ET) of a high density poplar stand were conducted in a typical rain-fed area of the Czech Moravian Highlands, Czech Republic, during 2012. Higher mean annual temperature, lowerprecipitation and period with drought occurred in this year. Sap flow measured on four sample trees was scaled to T and successfully validated by ET measured by Bowen ratio energy balance method. Since the sap flow measurements were available from June to September, a stomatal conductance model and leaf area measurements were used to predict annual T. It was found that when stomatal conductance is scaled to the canopy, a non-linear relationship between LAI and canopy conductance has to be taken into account. An increase of LAI from 0 to 3 had the most important impact on canopy transpiration. Apart from T and ET, interception was assessed by measuring rainfall at open area, canopy throughfall and stemflow. The ET of the understory and s
