Introduction

The purpose of this report is to test and evaluate a number of recent improvements and additions that have been made to the standard U.S. Geological Survey MODFLOW ground-water flow model since 2000. Thus, two new streamflow packages, SFR1 and SFR2 were compared against the original streamflow package STR. The new ground-water evapotranspiration package ETS1 was compared against the original EVT package. The unsaturated flow packages UZF1, HYDRUS, and MODFLOW-HYDRUS were also evaluated. Finally, the conduit flow package (CFP) was also tested and evaluated. Major advantages and disadvantages of some of these packages were pointed out.
