Lang range water finding geophysical resistivity meter
How to accurately find ground water?
The basic task of finding ground water is to find water storage
structure, then through analysis to determine and infer its water
volume, water level and water quality.
When looking for groundwater, the following points should be
considered in general:
1. Clarify the requirements for water sources
2. Understand geological structure(by geophysical resistivity
meter)
3. Find the water storage structure((by geophysical resistivity
meter)
4. Choose a water location
Geophysical resistivity meter is a useful tool for locating and
characterizing groundwater resources. They are commonly used in
hydro geological studies, environmental assessments, and well
drilling operations. By providing information on the depth,
location, and quality of groundwater, water finding instruments
help to improve water resource management and promote sustainable
development.
