The falling-head slug test method was used on both wells, in accordance with the design guidelines set out by Butler (1997). The slug was introduced into the boreholes by pouring a known volume of water into the boreholes, after which the head drop was monitored with groundwater transducers and dippers (see set-up parameters in Table 2).
Slug testing parameters
| Well . | Water level below measurement point (m) . | Volume of water injected (L) . | Expected theoretical rise in water level after slugging (m) . | Real rise in water level after slugging (m) . |
|---|---|---|---|---|
| Hilly borehole | 14.33 | 15.3 | 0.993 | 1.0 |
| Valley borehole | 5.170 | 15.3 | 0.993 | 0.990 |
