COMPARISON AND ANALYSIS FOR DIGITAL AND ANALOGUE OBSERVATION OF GROUNDWATER LEVEL

    Graphical Abstract
    • Abstract
  • the digital data and analogue data of groundwater level are analysed by comparison.The results show that their correlation coefficient is from 0.3956 to 0.9997.The synchronism for data of artesian well is relatively weak.Generally speaking, digital observation is better than analogue observation in accuracy.
