9.An unconfined aquifer with K-30 m/day is bounded by a stream on one side as shown in Figure 2, At a distance of 80 m from the stream, a well of 0.4 m diameter is pumped at rate of 3000 m³/day. What is the drawdown in the well? Q=3000 m³/day 20 m m 801 Figure 2 C C d=0.4 m K=30 m/day Impermeable Layer m³ / day
