Inundaciones en la cuenca del arroyo Ñireco. Medidas preventivas y correctivas, acciones estructurales y no estructurales.

Abstract

Bariloche has experienced significant growth in recent decades, expanding from the city center to the east and south, occupying high-risk areas for the population, such as the Ñireco Creek basin and floodplain. The overall objective of this study is to study the hydrological characteristics and dynamics of the Ñireco Creek watershed, with the goal of proposing corrective measures to reduce flooding and erosion risks in the lower reaches. To achieve this, work was carried out in a GIS environment based on basin parameterization, storm modeling, and subsequent analysis of hydrographs generated at the stream mouth for different intervention scenarios. The results demonstrate that the proposed actions and measures have strengths and weaknesses, so it would be ideal to implement them together, provided a corresponding individual assessment is made.
