For a sensible E-Flow exploration, information on a minimum set of abiotic parameters is required, like discharge, flow velocity, depth, bed composition (Table 1). There are also abiotic conditions that are not crucial but are good to have. Those conditions modulate the trait strategy composition within the boundaries of the crucial abiotic conditions. Examples are suspended sediment concentration, oxygen concentrations, temperature, nutrient concentrations. The data required and good to have may be obtained through different data sources and processing steps. Appendix A gives an overview of the available data sources.
