1. Loose pore water in desert and salt lakes:
a. Shallow exploration(>300m): VES and IP sounding
b. Deep/medium deep exploration: TEM
2. Deep cavern water:
Use EH-4 electrical conductivity imaging system as the main method and TEM, seismic method and radioactive as supplemented method
3. Tertiary cretaceous clastic rock: electromagnetic
4. Loess fissure and pore water: VES and IP sounding
5. Bedrock fissure water:
a. Shallow exploration: IP sounding
b. Concealed bedrock fissure water: TEM
6. Piedmont loose water: Res, seismic, electromagnetic
