Q4) Two observation wells 1700m apart have been constructed in a confined aquifer as shown if
fig below. the flow rate is 0.008m'/hr per unit width of the confined aquifer.Well I is drilled in soil
A with hydraulic conductivity 13m/day, and well2 in soil C with hydraulic conductivity 9m/day.
the soil zone B is between the wells, 600 m from well 1 and 300m from well 2. the water level is
6m above upper confining unit in well land 2.5m above upper confining unit in well 2.estamate the
hydraulic conductivity of soil B?
Well 1
Well 2
6 m
18 m
KA = 13 m/d
Kg = ?
Kc= 9 m/d
