Course for the transplant of reeds and aquatic phanerogams

The Life Lagoon Refresh project involves, among Conservation Actions, the transplant of seagrass and reeds in the Northern Venice Lagoon.

On July 12th 2019 a training course was organized at the Natural History Museum of Venice in order to involve stakeholders (fishermen and hunters) who will take care of these activities.

The course was held by researchers and professors from ISPRA and DAIS-Università Ca' Foscari of Venice and  it involved twenty practitioners. The topics of the course covered general aspects of the project’s purpose and content, specific aspects of biology, ecology and recognition of reeds and aquatic phanerogams as well as intervention methodologies for transplants and effects on fish and bird species.

This theoretical course will be followed by a practical course directly on field in the Venice Lagoon

Modelling activity

Numerical modelling was used as a supporting tool to investigate the circulation pattern and to define the most suitable project configuration. In particular, two- and three-dimensional hydrodynamic models were set up and used to optimize the rate of freshwater inflow (Action A.3) from the Sile river and the configuration of the morphological works (Action A.4), in terms of salinity diffusion and hydraulic effects.

The effect of the diversion on saline wedge intrusion in the Sile river was also assessed.

Online the Guide for the transplantation of reeds and aquatic plants

It is available online the didactic material distributed during the course for the transplant of reeds and aquatic phanerogams of July 2019 . The Guide can be downloaded from the Download area of this website, in the Technical Documents section of Action A.5, or directly from this link.
The guide, written by the University Ca’ Foscari of Venice and ISPRA, contains a brief description of the project, details of the species and techniques of transplantation and removal, and a description of the donor sites. The transplants, coordinated by the University, will be carried out by local stakeholders, mainly hunters, fishermen and small companies in the Venice Lagoon.

Project final design



The final design phases were all completed, including location of works, sizing, choice of materials, definition of construction details and schedule of execution. In particular, the design Actions A.3 and A.4 led respectively to the definition of the technical-operational details functional to the construction of the input of fresh water from the Sile to the lagoon (Action C.1) and to the realization of the morphological reconstruction (Action C.2).

The detailed technical aspects were defined on the basis of the collection of existing data and of the results of the preparatory investigations (Action A.2).


Topo-bathymetric survey


The topo-bathymetric survey of the Sile river embankment, where hydraulic work will be realized (Action C.1), and of the tidal area, where the morphological reconstruction will be carried out (action C. 2), was completed in order to have an updated elevation description of the project area. The survey was carried out by project partners OOPP and IPROS.

Using previously available data as well as results of surveys carried out within the project, a digital DEM (Digital Elevation Model) was created over an area of about 2 km² and with a resolution of 1 point/m².
