A $24-$hour aquifer pumping test with a constant rate of $15l\frac{t}{sec}$ was conducted in a fully penetrating well completed in a confined aquifer. The recorded drawdowns in a monitoring well MW located $20$ m away from the pumping well PW is given in the following table.

a$)$ Plot time versus drawdown data on a semi$-$log paper.

b$)$ Calculate aquifer parameters.

c$)$ Are there any boundaries? If there are, indicate the type and the number of boundaries.
