Caracterización y clasificación de la red hidrográfica de la cuenca del río Bobo, departamento de Nariño - Colombia

The object of this work was to make a morphometric characterization of the Bobo river watershed in the Nariño department in Colombia. A map was created from topographical maps (1:25.000 scale) using the drainage network and the limit of each 2nd order microbasin as database. Dimensional, drainage network and relief morphometric parameters were evaluated for a later hy-drological study. The drainage area was 224.97 km2, having a 71.31 km perimeter. The Bobo river watershed is considered to be 6th order and has 176 2nd order drainage channels, 34 3rd order drainage channels, 9 4th order drainage channels and 3 5th order drainage channels. Average drainage density is 3.71km/km2, reflecting its high density, having strong, dissected geological formation. The area has a typical Andean land-use pattern, having native wooded vegetation, traditional transitory potato and vegetable growing predominating.

A classificação arquivística: aspectos teóricos de sua constituição

Classification is a fundamental activity for the organization and management of archival document collection, as it is from this function that are based the priorities for the description and the bases for appraisal procedures. This article seeks through the fundamental works to the theoretical and methodological development of the Archival Science characterizes the historical and conceptual background from the classification notion. This article aims to answering some questions about the expansion of its importance during the development of its theory and its use on today. Is also sought to characterize the history of the Archival Science as a discipline since the classification was one of the first activities to be theorized.
