Resumen:
Although floods in watersheds have been associatedwith land-use change since ancient times, the dynamicsof flooding is still incompletely understood. In this paperwe explored the relations between rainfall, groundwaterlevel, and cultivation to explain the dynamics of floods in theextremely flat and valuable arable lands of the Quinto riverwatershed, in central Argentina. The analysis involved anarea of 12.4 million hectare during a 26-year period (1978–2003), which comprised two extensive flooding episodes in1983–1988 and 1996–2003. Supported by information fromsurveys as well as field and remote sensing measurements,we explored the correlation among precipitation, groundwaterlevels, flooded area and land use. Flood extension wasassociated to the dynamics of groundwater level. While nocorrelation with rainfall was recorded in lowlands, a significantcorrelation (P
