VOLONTE, Antonela  e  GIL, Verónica. Hydrogeomorphological index as a tool for the management of the river territory. Stream Basin of the San Bernardo, Argentina. Finisterra [online]. 2021, n.117, pp.199-214.  Epub 01-Ago-2021. ISSN 0430-5027.  https://doi.org/10.18055/finis20798.

The Hydrogeomorphological Index (IHG) is a tool for the assessment of hydromorphological indicators whose ultimate purpose is to determine the ecological status of river systems, important to conserve in order to protect the river ecosystem. The index uses nine parameters arranged in three groups: 1) functional quality of the system, 2) quality of the channel, and 3) riparian quality. The aim of this paper is to know and assess the hydrogeomorphological quality of the San Bernardo stream (Ventania System, Argentina) using the IHG methodology. Its application in the basin resulted in a “very good” hydrogeomorphological evaluation in the middle-upper section of the basin and “good” in the lower section of the basin, which is more anthropized. This allows us to outline as a first conclusion the importance of carrying out interventions in the river space that do not interfere with the naturalness of the river territory, a key aspect for the management of the basin.
