<p><p><strong>References:<br></strong><em>SAICE (2006)</em></p><p><strong>Method Summary</strong></p><p>Piezometers are used to measure the hydraulic head in the ground. In some instances, it is advisable to install piezometers to monitor the water table during compaction activities (SAICE 2006). Sufficient time, at least five to seven days, should be allowed to pass before the post‑compaction tests are performed to ensure that excess pore water pressures have dissipated (SAICE 2006).</p><p><strong>Accuracy and Precision</strong></p><p>This procedure is accurate and precise.</p><p><strong>Implementation Requirements </strong></p><p>Some experience and special equipment is necessary</p><p><strong>General Comments</strong></p><p>Piezometers are exclusively used for process control.</p></p>
