Habitat suitability models play an important role in forecasting the impact of remediation measures in rivers. The models depict the hydromorphological conditions, compare these with the habitat requirements of relevant animal and plant species and, from the degree of correspondence between the two, arrive at an assessment of habitat suitability.
The use of this kind of modelling gives rise to further unanswered questions however, particularly when it comes to considering the habitat requirements of aquatic organisms. In this project, we are quantifying the influence of various habitat requirements on the robustness of the modelling results. In addition, we are identifying the influence of morphology on the ecological impact of hydrological remedial measures in stretches which are subject to surges.
