Comprehensive Guide to Creating a MODFLOW Conceptual Model at Brigham Young University

This instructional guide provides a step-by-step approach to building a MODFLOW conceptual model using the appropriate software. The process starts with downloading, unzipping, and saving your files under a new name, followed by setting units and creating boundary coverage using three arcs. Additionally, the guide covers duplicating coverages to create source/sink areas, constructing river arcs with assigned conductance, and making a general head boundary for the lake. Finally, learn to create wells, build polygons, and initialize the MODFLOW model for successful simulation.
