Abstract: The climate change owing to the global warming has certainly generated more evaporation on the water surfaces. Consequently, there are more rainfalls and more water flow. The floods become more frequent, inundating more areas. By taking into account that both the yield and the transport of sediments in rivers happen due to the rainfall events and the water discharge in water bodies, it is obvious that the sediment discharge has increased in the river courses. This work aims to demonstrate the increase on the sediment yield in the drainage area of the large reservoir named Tres Marias, being concluded that both the climate change and the human activities are reasons for the erosion and sediment transport enlargement owing to the increase on the soil use for agricultural and other purposes.
