25. A confined aquifer with a uniform saturated thickness of 10 m has hydraulic conductivity of $10^{-2}$ cm/s. Considering a steady flow, the transmissivity of the aquifer in m2/day is _________________ (rounded off to one decimal place).
Solution:
Thickness =10 m
Hydraulic conductivity of
$10^{-2}$ cm/s
convert hydraulic conductivity units cm/s into m/day
= $10^{-2}*10^{-2} m/s$
= $10^{-4} m/s$
1day =86400 sec
=$10^{-4}*86400 m/day$
=8.64 m/day
Transmissivity is directly proportional to horizontal hydraulic conductivity Ki and thickness di.
Therefore,
Transmissivity $T= K d $
$T= 8.64 * 10 m^2/s $
$T= 86.4 m^2/s $
