Question

A pumiping test perceping of constant test with a discharge . +2m3/s was conducted in an unconfined aquer having an initial saturated thickness of som. there was a barrier boundary at 500m away from the pumping well as shown below. The drawdowns are measured in an observation well located from from the pumping wer a result of the test, T and 5 were estimated to be 0.015 m²/s and 0.10 respectively. At What time after the pumping statted, the boundary has begun to influence the drawdow. in the observation well? Hint: Assume a smallest drawdown of 0.005m. was detectable in the field.
