SPATIAL AND TEMPORAL ANALYSIS OF SOLID MATTER IN RESERVOIR OF HYDROELETRIC PLANT IN BARRA DOS COQUEIROS – GOIÁS - BRAZIL - DOI 10.5216/bgg.v33i2.25560

Abstract

The survey of suspended solids in a determined watershed is important to make correct decisions regarding the planning for a bowl, because the amount of solids is directly related to the land use. This study aimed to analyze the spatial and temporal distribution of the concentration of suspended solids (CSS) in the main source of the
lake in Barra dos Coqueiros, Goiás, state and its influence on the life cycle of the reservoir from March 2011 to August 2011. To achieve the proposed goals, it was used methods such as calculating the concentration of suspended solids according to the proposal of Wetzel and Likens (1991), calculating the flow of the sources of
water by the method of floats as proposed by Ramos and Oliveira (2003), Palhares (2007), and calculating the total solid discharge of the main sources of water (of the) using simplified method of Colby (1964). According to the data, according to the evaluation of the spatial and temporal distribution of suspended solids concentration
of the main sources of water in the reservoir of Barra dos Coqueiros, the main lake stands out among the sources analyzed, due to the higher concentration of suspended solids, ranging from 2,5 mgL–1 in the dry season to 14,5
mgL–1 in the rainy season.
