Abstract
My learning during my stay at GeoLab has been contextualized within the thesis of Lucas Mazal. In this thesis, a set of experiments have been designed and one of the purpose is the analysis and quantification of the feedbacks between hydromorphological processes and riparian vegetation. Some in situ experimentations with cuttings of individuals of young poplars will be planted in groups of different densities on a gradient of exposure to floods/hydric stress from the vicinity of the water channel on the alluvial bars to the floodplain. The survival and growth performance of poplars will be measured and analysed in relation with the density of individuals and the positions of the plots on the physical gradients. At the same time, water level will be measured by installing some piezometers close to the plantations. A pressure sensor it is submerged to the bottom of each piezometer to record pressures values. The measurements form each sensor will be converted to water table level above sea level after subtracting the atmospheric pressure recorded with another sensor located in the surrounds. Finally, the topographical variations in the surface of the alluvial bar will be monitored by using photogrammetric methods (Hortobágyi et al., 2017). The principle is to use images acquired from multiple viewpoints in order to construct dense three-dimensional points clouds of surfaces. By this way, sediment retention by poplars will be quantified, analysing the topographical variation along the experiment by constructing detailed digital elevation models.
