Nowadays coal mining is developing faster in the upstream area of Zambezi River Basin in Mozambique and it may influence greatly the water quality of the river basin in future. This makes relevant to evaluate the long-term impact of acid mine drainage from coal mining in Zambezi River Basin in Mozambique, establish a prediction system and sustainable monitoring program of water quality.
