Describe the two different types of geotechnical instrumentation that are used to measure groundwater levels, and explain what it is that each measures, how that measurement is used to determine the groundwater level. Also explain in what types of soils each of these different instruments should be used. Solution The instruments used to find ground water levels are i)Atex Dipmeter ii)Standared Dipmeter iii)Dipper log Iv)micropluge These Instruments are used for all kinds of soils with different measurements. First the instruments are dipped into the soil and based on the density.
