Fig. 3. Estimated water-table fluctuations 6 Apr. to 13 June 2002 based on weekly measurements adjusted with the use of the water-table recording device. Dashed line represents water-table data recorded weekly. Solid line shows the single-spike method hydrograph; where a single spike, inferred from the position of the magnet on the maximum water-table recording device (MWTRD) as an increase in the water-table level due to a precipitation event, is added to the weekly data. The height of the spike is determined using the magnet data, while the shape is that of the template spike.
