Second workshop on isotope-based studies of water partitioning and plant-soil interactions

Hannover | Germany | 28–30 July 2021

Due to the Corona Virus and its worldwide impact we decided to postpone the 2nd workshop on water partitioning and plant-soil interactions supported by EGU and the Volkswagen Foundation to 2021. Despite sincere hopes that the situation might improve significantly until July, we believe that under the given circumstances a gathering of a broad international audience is not feasible this year.

There are certainly more important things than science at the moment and we hope you and your families are healthy and safe. Our thoughts and prayers go out to those who have been affected. On a positive note, every crisis is also a chance and we as scientists have a great and unique opportunity now to help to make this a better world. So let’s look forward and work together!

The new date for the workshop is 28–30 July 2021. We will keep you updated for the new deadlines and further information. You can contact us at WaterPartitioningV2@isodrones.de. We look forward to seeing you in Hannover in 2021 for an exciting workshop!

Goals and topics


Over the last decade there have been tremendous advances in both technological development and process-based understanding of ecohydrological processes. Along with these, several long-standing assumptions have been questioned and novel, highly debated hypotheses proposed. The workshop addresses the urgent need to share experiences, discuss and advance knowledge about ecohydrological and physiological mechanisms that regulate the selection of different water sources taken up by plants.

The workshop aims to gather scientists with different scientific background (hydrology, ecology, plant physiology, soil science, remote sensing, …) but common research interests in using stable isotopes of water as tracers to study the cycling of water through the soil-plant-atmosphere continuum. We put a special focus on novel and innovative methods for the measurement and application of isotope-based methods, as well as interdisciplinary studies.

The key themes of the workshop include:

  • Water partitioning at various interfaces
    • Determination of root water uptake depths using isotope-based methods
    • Partitioning of Evapotranspiration in its components
    • Mixing models
  • Methodological advances in monitoring water stable isotopes
    • Advances in continuous monitoring techniques of soil and plant water isotopes
    • Extraction methods and related issues
  • Plant physiological aspects and constraints related to water partitioning
  • Combining water stable isotopes and other tracers to improve the understanding of ecohydrological processes
  • Isotopic labeling and multi-tracer applications (2H, 18O, 15N, 13C)
  • Large-scale studies employing water stable isotopes and upscaling of field studies
  • Novel approaches in combining isotope-based methods with remote sensing
  • Development and application of isotope-enabled models

Workshop format


Oral and poster presentations plus three invited speakers. A core element of the workshop are group discussions with the goal of defining a future agenda for isotope-based studies of water partitioning.

Conference fees


The conference fees include coffee, lunch, and a conference dinner. Additional financial support for a limited number of ECS is possible.

  • Regular: €250
  • Early Career Scientists (ECS): €180
