Soil Water Content Measurement Methods

This lecture covers the measurement of soil water content using indirect methods like neutron probe and dielectric methods, as well as direct methods such as the gravimetric method. It explains the process of determining water content, lime dosage, granulometry, and hydraulic conductivity. The lecture also discusses the limitations and advantages of the neutron probe and time domain reflectometry (TDR) methods, including the need for calibration and the influence of various factors on measurements. Additionally, it explores the principles of TDR, the advantages it offers in terms of accuracy and continuous measurements, and its applications in geotechnical and hydrological fields.
