20.3. Instrumentation and Sensors in Soil Monitoring

Try these first

1. 1.

   What does a piezometer measure?

   Hint

   Consider how pressure relates to water in soil.

2. 2.

   What data do fiber optic sensors provide?

   Hint

   Think about the physical properties related to stability.

3. 3.

   What is the primary function of a piezometer?

   • Weather monitoring
   • Measuring soil pressure
   • Mapping terrain

   Hint

   Think of how pressure relates to water in soil.

4. 4.

   True or False: Inclinometers can automatically trigger alerts if soil movement is detected.

   • True
   • False

   Hint

   Consider what makes a sensor 'smart'.

5. 5.

   Design a geotechnical monitoring system incorporating piezometers, inclinometers, and MEMS-based sensors for a proposed embankment project. Consider cost, durability, and data requirements in your design.

   Hint

   Think about how each sensor contributes to the overall safety of the project.

6. 6.

   Evaluate the effectiveness of fiber optic sensors compared to traditional electrical sensors in a seismic monitoring scenario. Discuss their strengths and weaknesses.

   Hint

   Consider environmental factors that could affect each type of sensor.
