Resumen

BORZI, Guido et al. Methodological proposal for the study of floods in plains areas with a lack of information. Dyna rev.fac.nac.minas [online]. 2020, vol.87, n.215, pp.221-228.  Epub 15-Ene-2021. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v87n215.85140.

The plains constitute areas of great potential for agricultural production frequently affected by floods. The objective of the work is to use a methodology that allows demonstrating under what conditions floods occur in plains areas with a shortage of basic information, taking as a case study the Samborombón River basin, located in the center-east of Argentina. For this, Landsat satellite images were observed and daily water balances were performed, to subsequently perform a statistical analysis of recurrence. The results obtained show that flooding is greatly influenced by previous soil water conditions. The methodology used allows estimating return periods in low-slope plain basins, requiring only satellite images of free access and daily average temperature and precipitation data, obtaining results that reflect the state of the basin after precipitation events.

Palabras clave : waterlogging; precipitation; evapotranspiration; soil available water; plains hydrology.
