Info: rootwater is developed with Python >= 3.7, within this repository updated for Python >= 3.10 (esp. regarding pandas v2.2)
This is a small toolbox for root-water-uptake (RWU) calculation from changes in soil moisture in the rhizosphere. The approach is described in Jackisch et al. (submitted to Biogeosciences). The general concept is an evaluation of observed diurnal soil moisture decrease and nocturnal stagnation or capillary-driven redistribution.
For referencing to sap velocity measurements, a collection of conversion tools to estimate sap flow in the active sapwood is included.
The documentation can be found at: http://rootwater.readthedocs.io
To use the package, clone the repository. Please make sure that your soil moisture time series has a localized time zone before applying the estimation of root water uptake.
