In particular, water pollution, the simplification of riverbeds (i.e., the modification of their morphology, leading to a reduction of natural habitats), and the alteration of hydrological regimes enable the development of low-diversity populations made up of tolerant <em>taxa <\/em>that grow rapidly. Therefore, the analysis of the macrophyte community provides overall indications of the level of alteration of water bodies caused by anthropogenic pressures, based on changes in the present macrophyte populations. The <strong>IBMR <\/strong>is based on a list of 210 indicator <em>taxa<\/em>, for which sensitivity to ammoniacal nitrogen and orthophosphate concentrations has been assessed from field data. However, trophic status is determined not only by nutrient concentrations but also by other factors such as light availability (which is in turn influenced by turbidity and shading) and current speed.     <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7aa1cfd elementor-widget elementor-widget-text-editor\" data-id=\"7aa1cfd\" data-element_type=\"widget\" data-e-type=\"widget\" id=\"index_iff\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h3>FFI (FLUVIAL FUNCTIONALITY INDEX)<\/h3>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-20567ed elementor-widget elementor-widget-text-editor\" data-id=\"20567ed\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>The index provides a summary assessment of the <strong>fluvial functionality<\/strong> and the causes of its deterioration, as well as precise guidance for redevelopment measures and a prior assessment of their effectiveness.
