7 Christoph Rüdiger Postgrad Seminar 2004 Internal routing Travel time T pi Velocity weight v -1

8 Christoph Rüdiger Postgrad Seminar 2004 Synthetic Experiment Variational Data Assimilation model output time obj. function assimilation step NLFIT (Kuczera, WRR, 1982) “Truth”: –10yr spin up –1yr full run “Experiment 1”: –One month only –Degraded soil moisture values (low catchment deficit) “Experiment 2”: –“Openloop 1” and changed forcing (33% lower radiation and 20% higher precipitation)

9 Christoph Rüdiger Postgrad Seminar 2004 Results “Experiment 1” DischargeSoil Moisture

10 Christoph Rüdiger Postgrad Seminar 2004 Results “Experiment 1”

11 Christoph Rüdiger Postgrad Seminar 2004 Results “Experiment 2” DischargeSoil Moisture

12 Christoph Rüdiger Postgrad Seminar 2004 Results “Experiment 2”

13 Christoph Rüdiger Postgrad Seminar 2004 Conclusion from Results Results show that runoff has useful information about soil moisture states Problems in semi-arid regions, when overestimation of water input due to degraded forcing data (potentially for too dry, as well!?) Monthly assimilation windows have positive impact, reduction of assimilation window should improve results further

14 Christoph Rüdiger Postgrad Seminar 2004 Future Work Including inter-catchment routing Comparison of different climates (real data) Assimilation of surface soil moisture
