The FHARMOR project has the following main general objectives:
- to assess the potential of hydro-morphodynamic modeling and of emerging remote sensing techniques to predict the spatial and temporal patterns of meso scale fish habitat;
- to develop a quantitative and applicable methodological framework able to effectively quantify fish habitat dynamics in alpine river systems of different size and over long reaches;
- to predict future scenarios of habitat availability in alpine rivers in response to sediment management and river restoration.
More specifically, the project aims to:
- determine the capability of hydrodynamic modeling to reproduce observed meso-habitat rating curves and to extend the discharge range of their validity ;
- determine the relevance of different resolution of the river geometry to quantify habitat dynamics;
- assess the range of variability of habitat metrics as consequence of river channel morphodynamics;
- determine the confidence with which multispectral imagery allows quantify the habitat rating curve in reaches of large, non-wadable piedmont streams;
- develop a first multivariate biological model for the habitat preferences of grayling;
- develop a practical methodology for the quantification of habitat dynamics in river reaches of different sizes and channel pattern, that can be easily used by river managers and integrated into existing methods for hydromorphological quality assessment;
- quantitatively predict the likely future change in habitat dynamics and availability of the target reaches in response to river restoration projects, namely based on local river widening or gravel augmentation measures.
