16.-17.10.2012: Faro workshop

IMPACT partners met for the fourth project workshop at the University of Algarve in Faro.
The results of the climate change scenario for our first catchment – the Treene river – are now available. Based on the general climate change scenarios for Northern Germany (small changes of the total precipitation amount but larger variability) we expected more frequent high flow and channel forming events. Very interesting to see that:

  • high and channel forming discharges will rather decrease than increase, and based on the models for channel geometry developed in IMPACT, we do not expect a large effect on channel geometry (cross-section width and depth),
  • summer low flows show the largest changes and significantly decrease, which also affects flow velocity and depth as well as habitat conditions and weighted usable area for fish (according to the hydrodynamic and habitat models).


16.-17.04.2012: Essen workshop

IMPACT partners met for the third project workshop at the University of Essen.
In summary: Some technical problems but we are progressing well.

15.-16.09.2011: Toulouse workshop

Just after the field campaign at the Célé river, IMPACT partners met for a project workshop at the University Paul Sabatier in Toulouse.
The main issues were:

  • to give progress reports,
  • to discuss the field campaign at the Célé river and planning of the field campaign at the Quarteira river in Portugal,
  • to discuss methods for modelling biota and the final biological assessment (e.g. Bayesian Networks),
  • to discuss how to develop the climate change and land use scenarios.


10.-11.03.2011: Kiel workshop

Just after the field campaign at the Treene river, IMPACT partners met for a project workshop at the Christian-Albrechts University in Kiel.
The main issues were:

  • to give progress reports,
  • to discuss the field campaign at the Treene river and planning of the field campaign at the Célé and Quarteira river,
  • to detail the model parameters (including water quality) and the accuracy needed based on the habitat requirements of the model species,
  • to discuss the model interfaces between the abiotic models and to ensure that the habitat data required by the biologists can be delivered by the abiotic models.


22.02.2011: Habitat and dispersal modelling workshop

A habitat and dispersal modelling workshop was organized by the IMPACT partners and hosted by the University of Duisburg Essen 16.02.2011. In IMPACT, species distribution models will be used to identify possible source populations in parts of the catchment where no biological data are available. Dispersal models for fish and invertebrates will be developed in IMPACT to assess the species pool available and the time neccessary for re-colonizing a restored river reach, and habitat models to predict the species composition based on the species pool and the habitat characteristics (flow-velocity, -depth, substrate).
Impact habitat and dispersal workshop
After presenting the overall and specific objectives of the projects, the participants discussed and identified several possibilites for cooperation as well as synergies. The workshop was well-timed since virtually all projects just started. All participantes agreed and were very interested to further exchange ideas, results, and to cooperate. For example, several participants will work in the same catchment and agreed to harmonize their study designs so that they can exchange and compare data and results.

Everybody working on species distribution and dispersal model is invited to join this little but vital group at one of the next meetings – just email the IMPACT partners!

28.12.2010: Habitat and dispersal modelling workshop

A habitat and dispersal modelling workshop was held in Essen 16.02.2011. Dispersal models for fish and invertebrates will be developed in IMPACT to assess the species pool available and the time neccessary for re-colonizing a restored river reach. IMPACT project partners are organizing a workshop to present the modelling approaches and to identify possible collaborations and synergies with two other projects at the University of Duisburg Essen and Senckenberg.

11.10.2010: IMPACT started!

A successful and fruitful kick-off meeting was held in Berlin 07.-08.10.2010. The project partners presented their modelling approaches and discussed model interfaces. Moreover, the consortium started to select near-natural study reaches (“receiving reaches”) and to organize the field campaign.
