A well of 0.1 m radius is part of a well point network to keep an excavation dry (Figure P6.13). The groundwater at the far edge of the excavation must be 0.5 m below the base.
(a) Calculate the radius of influence.
(b) Calculate the maximum drawdown.
(c) Plot the drawdown curve.
(d) For the radius of influence in (a), (i) calculate the discharge if the well radius increases to 0.2 m, and (ii) compare it to the discharge for the 0.1-m-radius well.
