Abstract By removing the typical interference signals and picking up the trend from the observations the signals can be decomposed effectively with the EMD method.So the EMD method is an adaptive highpass filtering method without enacting bandwidth beforehand and fits for groundwater data decomposition and analysis.
Key words ：
empirical mode decomposition (EMD)
groundwater data
trend changes
filter
adaptive high-pass filtering
