Question 3 Steady Confined Large Diameter The Drawdown Within The Well Sw Versus Time T Of The Confined Aquif 2 (26.26 KiB) Viewed 47 times
Question 3: (steady - confined - large diameter) The drawdown within the well 'sw' versus time 't' of the confined aquifer is given below table for a discharge of Q-320 m³/day. Note that the well screen 'rse and the well radius 'Tw' are equal (45 cm). Determine the transmissivity 'T' and the storativity coefficient 'S' using Modified Papadopulos and Copper type-curve method.
