Monitoring of Riparian Vegetation Growth on Fluvial Sandbars

The paper proposes a simplified methodology to track the evolution of vegetation patterns over a central sandbar of the Po River, Italy, by means of a fixed video camera installed on the top of a bridge pier. Looking downstream, the camera acquires images every twelve hours while hourly water levels are derived from a radar hydrometer located 300 m upstream of the study area. The vegetation growth rate is computed analysing several images covering the period July–December 2017, characterized by a dry period during the summer/autumn and a flood at the end of the year. The tracking of the vegetation patterns bounds provides some general indications on the role of a transient hydrology on the plants’ dynamics.
