Water Quality Data and Analysis

The data and information was targetted to cover the Qinhuai River basin where the Guanghzou City inside. In summary, below is the list of the data which have been collected and analyzed: 

  • GIS data: landuse, river system networks, hydrotopography, water quality observation stations; population density; administrative boundaries.
  • Hydro-meteorological data: daily rainfall, maximum air temperature, mean air temperature, minimum air temperature and relative humidity.
  • Water quality for river and Industrial/domestic wastewater in each administrative region of Guanghzou
  • Spatio-temporal variations of river water quality.
  • Relationship between water quality and socio-economical development.
