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. <br> 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.
