Hives of the morphologically homogeneous traits of the typed natural hydrographic network

Perimeter of the hives of the morphologically homogeneous traits of the typed natural hydrographic network. The portion of the riverbed considered is that affected by the full formation (times of return: 1.5-2 years). Differentiated traits based on: significant hydrological discontinuities, different concentration of bridles/thresholds, class of confinement, morphological type, presence or absence of embankments, width of the hive, longitudinal slope of the hive, physiographic unit of belonging.
