The aims of the Flobar2 project were to address knowledge-gaps in present scientific understanding of river-floodplain biological and physical systems 
by exploring:    
- scientific aspects of the impact of different flow regimes on the growth and regeneration of floodplain plant species and the impact of floodplain vegetation 
on flood retention.    
Furthermore the project targeted to integrate scientific understanding of these interactions between abiotic and biotic factors on floodplains with 
the decision-making mechanisms involved in water allocation in river catchments. 
            

The project seeks to contribute to the enhancement of the ecological quality of riparian ecosystems in Europe through the development of water allocation 
guidelines.   
A main focus of the project was on floodplain forests   
   
 The project developed scientific guidelines for the application of river flow prescriptions which benefit floodplain ecosystems while maintaining acceptable 
levels of flood control.    
-Furthermore aspects of the relationships between hydrological inputs to a floodplain and plant response measured in terms of water consumption, growth 
and the diversity of regeneration strategies were quantified    
-Additionaly the flow resistance associated with woody riparian vegetation using field studies and mathematical modelling was investigated.    
-During the project the effectiveness of selected institutional arrangements for restoring floodplain environments at different spatial scales and 
in different national/local settings was investigated and compared.
