Abstract:

The NODFLOW model calculates the head in the node with a pumping well. This head is not the actual head in the well, however. The head losses caused by ground water flowing to a small diameter withdrawal point are not accounted for. It is typically necessary to predict drawdown in the well as well as drawdown in the aquifer. For this reason, several new routines were written for the MODFLOW model. These routines allow the user to calculate drawdowns in the wells. These drawdowns include the effects of flow convergence and well efficiency. It is also possible to create a file of time versus drawdown at a well and have the output show an alphanumeric well name.
