Groundwater surface elevations based on Environment Canterbury (ECan) and Tonkin & Taylor Ltd (T&T) measurements. Water level dips were converted to free surface elevations, based on surveyed well-head levels. Surface models were fitted to the elevations recorded at these wells and the adjacent rivers immediately prior to the 4 Sept 2010, 22 Feb 2011, 13 June 2011 and 23 Dec 2011 earthquakes. The free surface elevations only provide mean values at the time of each earthquake and are only suitable for back analysis purposes. They are indicative only, with no allowance for extreme or seasonal fluctuations, or for localised perturbations (e.g. changes in topography or permeability) away from the measured well. They are not suitable for design. |
