Experimental investigation of the kinematic characteristics of flow in a meandering flume with flexible vegetation on the bed: preliminary results

European Vegetation Archive: now EVA really starts!
2014
European Vegetation Archive (EVA) was announced as a new initiative of the European Vegetation Survey at the EVS Meeting in Vienna in 2012. The aim of EVA is to create a centralized database of European vegetation plots by storing copies of national and regional databases on a single software platform using a unified taxonomic reference database. EVA does not affect the ongoing independent developments of source data bases and it guarantees that data property rights of the original contributors are re spected. EVA Data Property and Governance Rules were approved and the EVA website (www.euroveg.org/evadatabase) was established in 2012. Since then several European vegetationplot database…

Effect of flexible vegetation on localized erosion processes

Eperimental observations on the effect of flexible vegetation on flow velocity and turbulence fields
2011
Vegetation altering hydrodynamic conditions of an open channel flow controls the exchanges of sediment, nutrients and contaminants. Thus, the knowledge of the hydraulic characteristics of flow over vegetation is very important to support the management of fluvial processes. But, the analysis of the hydrodynamic conditions is complex because vegetation is flexible in varying degrees and it oscillates in the flow changing position. Furthermore, because of temporal changing of roughness due to natural vegetative growth, the response of vegetation to the flow can change in time. Many theoretical and experimental investigations have been performed in order to analyze both the mean flow and turbu…

The habitat monitoring under article 17 of the 92/43/eec Directive in Italy: the contribution of vegetation science
2016
The 4th National Report ex Art. 17 of the 92/43/EEC Directive in Italy (period 2013-2018) will try to fill a number of gaps still affecting the former versions of the Italian Reports, where territorial data were still missing for large parts of the country and the assessment was mostly based on the use of the expert opinion. Similar inconsistencies also emerged in other European countries (State of nature in the EU, EEA 2015). In order to reach this aim, a nationally shared protocol for monitoring the vegetation-based Annex I Habitats is currently under development. The most prominent issues addressed by the ongoing project are: i) fixing standardized, updated and scientifically grounded me…
Experimental analysis of the effect of non-uniform submerged vegetation on flow characteristics at the apex section of a meandering laboratory flume
