This guide informs the user about the files, structures, and parameters provided in the electronic resources of the transient DVRFS model. Input, output, and model simulation modes with MODFLOW-2000 of likely utility to the user are described. Input includes observation packages that contain observations of hydraulic head and head change, flows, and flows associated with groups of constant head cells along portions of the model boundary. The source of information and assumptions on which the observation values and weights are based is discussed. These observations provide model users a tool to evaluate model fit that is critical to analyzing any application of the DVRFS model. In addition to characterizing the input and output of the DVRFS model, the mechanics of creating such output is explored for several types of model modes: forward, parameter-sensitivity, and parameter-estimation. For typical users of the DVRSF model, two common modifications of the model arise: predictive pumping scenarios and conversion of the model from a transient to a steady-state simulation. Editing of the model archive files to achieve both of these model modifications is outlined with examples.
