Resumen
This study presents a qualitative and quantitative analysis of the water in the Cuiaba River at
the Hydrometric Station of Porto, which was installed in 1933 between the cities of Cuiaba
and Varzea Grande in the state of Mato Grosso. In the twelve field campaigns put into
practice from December 2011 to February 2013, related to this study, the flow was measured
and sediment collected. In six of those campaigns, three in the dry season and three in the
rainy one, samples of water were collected too. A hydrometric vane was used in the flow
measuring; in the collection of suspended sediment and water samples it was used a sampler
USDH-59 and a Rock-Island sampler to collect sediment in the bed of the river. The method
of Equal Width Increment was adopted to collect suspended sediment; the bottom sediment
and water samples were collected at 1/6, 1/2 and 5/6 of the total width of the river. The
estimated Total Solid Discharge was calculated using the simplified method of Colby. In this
study the results of liquid and solid discharge were associated to the aspects of water
quality, according to Item I of Article 3 of General Guidelines for Action Federal Law No.
9433 of January 8, 1997. A rating curve was created with the flow measures, which was
compared to another one provided for the same hydrometric station by the National Agency
of Water – ANA. The concentration of suspended sediment, together with the water flow,
produced a rating curve of concentration which was compared to concentration data from
other studies, beyond being used to calculate the total solid discharge – TSD. A rating curve
of solid discharge related with water flow was also created and compared to another studies
about the Cuiaba River. To analyze water quality, the CONAMA Resolution 357/2005 and
the Water Quality Index – WQI – adopted by the state of Mato Grosso were used. The results
of flow proved a direct relation to the dry and rainy seasons and showed clearly the
regularization of the flow due to the Manso Reservoir (also called APM Manso). The results
of solid discharge were also closely related to the seasons, beyond indicating an human
influence in its production. In the results about water quality, some parameters are in
disagreement with the CONAMA Resolution 357/2005, specially total phosphorus,
Escherichia coli, dissolved oxygen and turbidity. As for the Water Quality Index, the study
section got grade 60 which is considered by the index as AVERAGE. This study is concluded
also observing that solid discharge, flow and water quality are closely related and should not
be dissociated.
