| Abstract | Severe hydrological droughts in the Amazon have generally been associated to strong El Niño events. More than 100 years of stage record at the port of Manaus confirm that minimum water levels generally coincide with intense warming in the tropical Pacific sea waters. During 2005, however, the Amazon experienced a severe drought with great ecological and social impact, and who was not associated to an El Niño event. Unless what usually occur during strong El Niño events, when negative rainfall anomalies usually affect central and eastern Amazon drainage basin; rainfall deficiencies in the drought of 2005 were spatially constrained to the west and southwest of the basin. In spite of this, discharge stations at the main stem recorded minimum water levels as low as those observed during the basin-wide 1996-97 El Niño related drought. Besides this, stage data and satellite images indicate that floodplain lakes surface areas were more reduced during the recent drought. This paper examines why river discharges were so low during the 2005, even though rainfall deficits were restricted to a fraction of the whole basin, and why the impacts on the main stem floodplain were so severe. The analysis of river discharges along the main stem and major tributaries during the drought of 2005 revealed that the recession on major tributaries began almost simultaneously. This was not the case in the 1996-97 drought, when above normal contribution of some tributaries for a short period during high water were crucial to partially counter balance high discharge deficits of the other tributaries. Since time-lagged contributions of major tributaries are fundamental to damp the extremes in the main stem, an almost coincident recession in almost all tributaries caused a rapid decreased of water discharges during the 2005 event. Perhaps one of the most important lessons to be learnt from the drought of 2005 is that, from a hydrological point of view, more importantly than the size of the area affected by negative rainfall anomalies is the timing and location where those rainfall deficits occur. In conclusion, localized drought might have a greater impact on main stem river discharges providing rainfall deficiencies produces a simultaneous recession of major tributaries. |
