The fluvial system can be characterized from the application of geomorphological indicators. These allow understanding the dynamics of the system as well as carrying out a status diagnosis for good management. The aim of this work was to apply a group of geoindicators to diagnose and monitor the environmental status of the Oro basin (38° 4' 56.9"S 61°56' 24.17"W), Argentina. The geoindicators were grouped according to the application objective (diagnosis and monitoring) and the time scale (long, medium and short term). The field work was carried out during the period 2019 - 2021, which was the main input of information. The application of geoindicators in the medium and long term allowed the environmental characterization of the basin and recognition of the most important characteristics in terms of its fluvial dynamics, highlighting the variability of rainfall, which when it occurs in an extreme way, due to the morphometric characteristics of the basin, favors the occurrence of stream flooding events. In the short term, they allowed the identification of those indicators to be monitored to ensure optimal hydrogeomorphological quality, mainly in the riparian areas, which resulted in the highest degree of transformation.

Building risk spaces differ according to the history of the urban development and the environmental context of each city. The aim of this work is to analyze historical-territorial periods that generated the construction of flood risk areas in the city of San Carlos de Bariloche, Río Negro, Argentina. The Dagwood Sandwich methodology was applied to analyze the urbanization and its transformations over time and the role played by the environment and the impacts caused by society. Correlations were observed within six historical-territorial crosscutting moments at different scales (local, provincial, national and international) and the development of exposed spaces to different dangers. This methodology allows identifying and acknowledging the current and historical environmental situation, in order to forecast possible trends of urban expansion and the generation of new flood-risk territories.
