Data underlying the publication: How to build vegetation patches in hydraulic studies: a hydrodynamic-ecological perspective on a biological object

We provide data on the morphological and biomechanical characteristics of four species of fully submerged freshwater aquatic macrophytes that can grow into well-defined patches. The dataset covers three relevant levels of organisation: individual plants (inside patches), isolated patches and multiple neighbouring patches. During the field sampling, the following parameters were collected and paired with data on local hydrodynamic conditions (water depth and flow velocity measurements): Plant level: plant height, dimensions of stem cross section, Young’s modulus, second moment of area, flexural stiffness, Cauchy number. Patch level: width, length, height and their allometric relationships; density; fresh and dry mass per m2. Between-patch level: species composition (% cover in the patch), minimum and maximum gap size (distance between consecutive patches), distance between patch centroids.
