Determination of forest stand transpiration and evaporation using eddy covariance and
As part of the project , we want to decompose the shares of total water-loss of forest cosystems. The determination of forest water fluxes appears simple since the method of eddy-covariance has been established. Indeed it is an excellent tool to measure the whole stand water exchange. However, to distinguish transpiration and evaporation additional measurements are necessary. Therefore the installation of several sap-flow systems is provided, to obtain reliable results which will describe the water demand of the forests in a differentiated way.
Regionalization of Evapotranspiration (ET) at the Thuringian Basin
Being part of the
In detail we will elaborate on existing methods on regionalizing local measurements of ET. Further on the hydrological model will be transfered towards the Thuringian basin. There we will face the model with remote sensing data and integrate the regionalization scheme into mHM. This model setup will be optimized against present data (water discharge at the outlet as well as surface temperature).
