[Objective] In order to provide technical reference for the study of the relationship between plant and groundwater depth in desert areas and the search for groundwater resources

several rapid and accurate techniques and methods for obtaining groundwater depth in desert area were analyzed and selected.[Methods] Through the analysis of observation wells

soil impedance coefficient

ground penetrating radar and nuclear magnetic resonance

the principles

advantages and disadvantages and application of several methods for measuring groundwater depth

such as seismic exploration technology

and factors such as comprehensive operation convenience

accuracy and equipment price

etc.

are analyzed to select several rapid and accurate techniques for obtaining groundwater depth in desert areas.[Results] When detecting groundwater depth in desert area

we should be familiar with the principle

advantages and disadvantages of these methods

and consider the convenience of technical operation

data precision and the price of instrument and equipment

labor costs and other factors as well to comparative trade-off analysis for the selection of scientific

reasonable technical programs.[Conclusion] It is the cheapest and most accurate method to determine the groundwater depth in desert area

and when the terrain conditions are complex and the traffic is not convenient. Nuclear magnetic resonance (NMR)

seismic detection in one case

if groundwater depth is measured in homogeneous sandy land

a soil impedance meter could be used.
