69timet + 120Piezometer installed at Point X 0 outside reclamation sitetimet+120Piezometer installed at Point XT within reclamation siteAverage excess pore water =pressure at Point X 1 on Day xAverage of the pore water pressure recorded bypiezometer at x 1 between time (t + T L ) and (t + 24+T L )- Average of the pore water pressure recorded bypiezometer at x 0 between time t and (t + 24)Legend:Px 0 = Pore water pressure recorded by piezometer at Point x 0 outside reclamation.PXi= Pore water pressure recorded by piezometer at Point XT within reclamation.T L = Time lag of response between piezometers at Points x 0 and ^.Notes:1. Automatic electronic devices should be used to facilitate recording of pressure data.2. Pressure reading should be logged continuously.3. Piezometer outside the reclamation is installed for the purpose of eliminating the tidal effect on thepiezometer reading taken inside the reclamation,Figure 9 - Tidal Effect on Pore Water Pressure Measurement
