Since 1999, the Manso hydropower plant has been regulating the Cuiabá River, which is
one of the two main affluents of the northern Pantanal of Mato Grosso, responsible for
the flooding of at least 20,000km2 of the world?s greatest floodplain. Since the initiation
of regular reservoir operation in 2002, discharge at the beginning of the wet season
(November?December) has been reduced by about 20%. Current power plant operation
increases dry-season discharges from about 100m3/s to 150m3/s, resulting in water levels
approximately 1m above those recorded before regulation. Rainy season runoff higher
than 400m3/s is retained in about 6 weeks and the period of drying up is anticipated. Hydrograph analysis in conjunction with a planialtimetric field survey determined that discharge of 240m3/s is the minimum required to initiate flooding in the Pantanal in the northern Cuiabá River floodplain, while runoff of 355m3/s is necessary to guarantee consistent flooding of the same. Constrained by positive linear trends in precipitation and discharge, which were detected through a time series analysis of a 68-year period, two reoperation alternatives are proposed, which would not reduce mass balance of power generation, but can guarantee river overflowduring the months November through May, minimizing the impact on ecological functions of the floodplain. |
