| Resumen: | The document specifies laboratory methods to determine the water retention characteristics of soil. It is, however, restricted to measurements of the drying or desorption curve. Four methods are described to cover the complete range of soil water pressures: a) method using sand, kaolin or ceramic suction tables for determination of matric pressures from 0 kPa to -50 kPa; b) method using a porous plate and burette apparatus for determination of matric pressures from 0 kPa to -20 kPa; c) method using a pressurized gas and a pressure plate extractor for determination of matric pressures from -5 kPa to -1500 kPa; d) method using a pressurized gas and pressure membrane cells for determination of matric pressures from -33 kPa to -1500 kPa. This document provides guidelines to select the most suitable method in a particular case. |
