Examples

# Pumped well discharge rate [m3/s]
Q=0.0045
# Aquifer Transmisivity [m2/s]
Transm=0.012
# Well radius [m]
Rv=1.2
# Storativity [-]
STRR=0.0001
# Time [s]
T = c( 1.88,2.36,2.97,3.74,4.71,5.93,7.46,9.40,11.83,14.89)
# Dimesionles time [-]
TD=T*Transm/Rv/Rv/STRR
# Well drawdown during pumping test [m]
S =c(0.006,0.008,0.010,0.012,0.015,0.019,0.024,0.03,0.038,0.047)
