Hydromorphological conditions of small streams in North Italy and West Austria

Considering the entire fluvial network of Tyrol and South Tyrol, 81 sampling sites were selected according to the following requirements: (1) degree of hydrological disturbance (undisturbed, residual water, temporal residual water or hydropeaking); (2) type of water regime (e.g. groundwater, glacial, nivo-pluvial); (3) degree of morphological disturbance (either near natural conditions or anthropogenic changed conditions); (4) dominant land use type in the catchment with a total area of 4 ha (either grassland, forest, vineyard/orchard or urban settlement); (5) hormone pollution (based on the location of the sample point - before or after sewage treatment plant, or pesticide suspicion).
