A) CALCULATION of K according to HO

A) CALCULATION of K according to HOOGHOUDT and ERNST

Applicability and terms of use

- Borehole radius “r” is in the range 3 cm < r < 7 cmm
- The depth of the water column during the steady state is in the range 20 cm < H < 200 cm
- The depth interval for the recovery observation is y > 0.2H

Observed parameters in field (see Figure 2, Table 2)

H – stable GW level [m]
yter – depth to stable GW level from the surface [m]
y0 – GW level difference from stable GW after its removal, at the beginning of the rise rate measurement [m]
yn – GW level difference from stable GW at the end of the rise rate measurement [m]
y – GW level during the rise rate measurement [m]
r – borehole radius [m]
