                         variability of rainfall can significantly affect all components of 
                         the water balance. This variability and the lack of detailed 
                         hydrological and meteorological data in both temporal and spatial 
                         scales have created uncertainties regarding the closure of the 
                         water balance for the Amazon basin. Previous studies in Amazonian 
                         micro-catchments suggested that both the unsaturated and 
                         groundwater system, which are not taken into consideration in 
                         basin-wide water budgets published in the literature, play an 
                         important role in controlling the timing of runoff generation. In 
                         this paper, the components of the water balance and the variations 
                         in different storages within the system were examined using 3 
                         years' data from a 6·58 km2 micro-catchment in central Amazonia. 
                         The role and relative importance of the various stores were 
                         examined. The results show a strong memory effect in the 
                         groundwater system that carries over seasonal climate anomalies 
                         from one year to the next and affects the hydrological response 
                         well beyond the time span of the anomaly. In addition, the deep 
                         unsaturated zone was found to play a key role in reducing most of 
                         the intraseasonal variability and also affected the groundwater 
                         recharge. This memory effect is crucial for sustaining streamflow 
                         and evaporation in years with rainfall deficiency. The memory 
                         effect caused by storage in the groundwater and unsaturated 
                         systems may also prevent the closure of annual large-scale water 
                         balances, which assume that storage returns to a standard state 
                         each year. Copyright © 2007 John Wiley \& Sons, Ltd..",
