摘要
the impacts of precipitation on the water quality along the purus river, located in the brazilian state of the amazonas, was investigated using data of precipitation estimated by satellite and information about water temperature, conductivity, ph, turbidity, dissolved oxygen and total suspended solids. the data were acquired in four different areas along the river. the results showed negative correlation between precipitation and turbidity. they also showed positive correlation between precipitation and temperature, conductivity, dissolved oxygen, total suspended solids and ph. the land use together with the rainfall regime seems to be the main sources of impact on the water quality around the sampling places.
