Part 2 of Deliverable 2.1 ' Multi-scale framework and indicators of hydromorphological processes and forms' provides fuller details concerning some specific topics outlined in Part 1.
A method for automating delineation of river reaches is described and tested (Annex A). Information on the natural riparian and aquatic plant communities of Europe is tabulated (Annex B). Flow regime analysis (Annex C) is explored in far greater detail than in part 1, with indicators fully defined and several different methods described. Quantifying the calibre and structure of river sediments is a challenging task, so Annex D goes into this topic in depth, providing the information required for sampling regimes to be designed. In Annex E, some additional information on the classification of rivers and floodplains is provided.
Following a brief description of sediment budgets (Annex F), a more extended description of empirically defined threshold conditions between rivers of different type (Annex G), and a description of a range of sediment transport formulae (Annex H), Annex I presents a series of modelling applications that have been developed for network, reach and habitat scale applications. These are presented in the form of applications of particular models to individual European rivers, many of which are the focus of catchment case studies in Parts 3 and 4 of Deliverable 2.1.
Deliverable 2.1 Part 2 concludes with a review of how remote sensing can contribute to assessment of particular features, processes and characteristics that are required during the application of the hierarchical framework.
