  abstract = {{S}tudy region: {T}he upper {A}mazon {R}iver, where the water level measured at the {T}amshiyacu station ({P}eru) shows seasonal variability of seven meters. {S}tudy focus: {K}ey parameters for the flood recession period (beginning, end and duration of the low-water period, velocity of water falling and rising, and inversions in the direction of stage change known as "repiquete" events) are analyzed for the period 1985-2015, along with their relationship to rainfall integrated in the upper {A}mazon basin at {T}amshiyacu. {N}ew hydrological insights: {T}he low-water period lasts about four months, beginning, on average, at the end of {J}uly and ending in early {N}ovember. {S}ince the late 1990s, the low-water period has tended to end later, last longer and the flood recession ends more abruptly than it used to. {T}his may be related to the increased frequency of dry days during the austral winter in the central and southern part of the basin and to increased and more intense rainfall in late spring ({N}ovember-{D}ecember). {R}epiquete events are frequent, 8 each year on average, and sometimes very acute: 18 events with a water-level reversal greater than one meter were registered during the 1985-2015 period. {T}hey are related to unusual, intense and extended rainfall during the week preceding the repiquete. {E}xtensions of this preliminary work are suggested, as well as possible implications for recessional agriculture.},
