Correlations chart: Tool to analyse the dynamics of water quality parameters AGRIAMBI
Rocha,Cézar H. B.; Casquin,Antoine P.; Pereira,Renata O..
ABSTRACT The search for statistical techniques and forms of graphical representation that can explain the most relevant correlations among limnological variables can help interpret phenomena in a body of water. The objective of the article was to propose a graphical representation of the correlations among limnological variables applied in the contributing basin of the Dr. João Penido reservoir, in Juiz de Fora, Minas Gerais state, Brazil. Six sections were monitored monthly from May 2012 to April 2014, analysing 15 water quality parameters and their statistical correlations. The correlations were represented graphically with the program Gephi 0.8.2-beta. The influence of organic matter (of natural and anthropogenic origin resulting from pasture runoff and...

Loss of macronutrients (N, P, K) in the hydrographic basin of the River Ivaí, an affluent of the River Paraná BABT
Guiraud,Deborah Maria Corrêa; Lenzi,Ervim; Luchese,Eduardo Bernardi; Fávero,Luzia Otília Bortotti.
Influence of some environmental variables in the loss of macronutrients N, P, K, from the hydrographic basin of the River Ivaí were analysed. Water samples of the river were monthly collected for five consecutive days during a year. In terms of total intervals of average monthly values and total average values experiment results, in mg L-1, were: N (0.32-3.22 and 1.65); K (0.73-2.69 and 1.38); P (not detected-0.39 and 0.076); COD (0.21-36.0 and 12.8); O2(dis) (1.89-8.40 and 5.43); and temperature (&#186C) (16.0-30.8 and 24.6); pH (5.18-8.50 and 7.15). Statistical analysis of data showed that quantity of macronutrient (N, K, P) carried off from the hydrographic basin of the River Ivaí were directly correlated to fluviometric levels (caused by rainfall...
