to the datum) at the given node location and the flows across each of the 4 boundaries for Model 1 (Dirichlet conditions). Note that abstraction (Q) is negative (by convention) for water leaving the aquifer. Calculate your flows over the boundaries as positive if into the aquifer and negative if out of the aquifer. Report the following: [10 marks] a) Head at pumping node [m] b) Flow through boundary AB [m3/d] c) Flow through boundary DC [m3/d] d) Flow through boundary AD [m3/d] e) Flow through boundary BC [m3/d]
