Abstract

This research aims to analyze the seasonal rainfall behavior of the state of Pará in the period of 30 years (1986-2015), through the analysis of Ward's hierarchical grouping through data from 108 rainfall stations of the HydroWeb of the National Water Agency (ANA), to contribute as a subsidy for the management and planning of water resources in the region. The results indicated from the validation indexes, the number of formation with two (2) or eight (8) groups, that is, of two and eight homogeneous pluviometric regions. The two regions separate the state between the north with the highest rainfall and the south with the lowest rainfall, with a variation in seasonality shown in the climatic normal of the regions. Meanwhile, the eight regions showed different rainfall patterns with variations in monthly rainfall mediated by regions. It is concluded that the pluviometric behavior in the state as a whole is not homogeneous, however, with the grouping a similar behavior was observed, forming homogeneous pluviometric regions, both in relation to the temporal variation of rain throughout the year, as well as good coherence space. This information can serve as a subsidy for the management and planning of water resources in the state of Pará.
