River biota are affected by global reach-scale pressures, but most
approaches for predicting biota of rivers focus on river reach or segment
scale processes and habitats. Moreover, these approaches do not consider
long-term morphological changes that affect habitat conditions. In this
study, a modelling framework was further developed and tested to assess
the effect of pressures at different spatial scales on reach-scale habitat
conditions and biota. Ecohydrological and 1D hydrodynamic models were used
to predict discharge and water quality at the catchment scale and the
resulting water level at the downstream end of a study reach. Long-term
reach morphology was modelled using empirical regime equations, meander
migration and 2D morphodynamic models. The respective flow and substrate
conditions in the study reach were predicted using a 2D hydrodynamic
model, and the suitability of these habitats was assessed with novel
habitat models. In addition, dispersal models for fish and
macroinvertebrates were developed to assess the re-colonization potential
and to finally compare habitat suitability and the availability / ability
of species to colonize these habitats. Applicability was tested and model
performance was assessed by comparing observed and predicted conditions in
the lowland Treene River in northern Germany. Technically, it was possible
to link the different models, but future applications would benefit from
the development of open source software for all modelling steps to enable
fully automated model runs. Future research needs concern the physical
modelling of long-term morphodynamics, feedback of biota (e.g.,
macrophytes) on abiotic habitat conditions, species interactions, and
empirical data on the hydraulic habitat suitability and dispersal
abilities of macroinvertebrates. The modelling framework is flexible and
allows for including additional models and investigating different
research and management questions, e.g., in climate impact research as
well as river restoration and management.
