MODPATH6 models used to evaluate effects of complexity on groundwater age metrics in the Fox-Wolf-Peshtigo watersheds, Wisconsin

This data release contains five groundwater particle-tracking models (MODPATH6) of northeastern Wisconsin, USA, that were developed to work with three MODFLOW models that have differing levels of complexity. The previously developed MODFLOW models (https://doi.org/10.3133/sir20175010 and https://doi.org/10.5066/F73J3B3P) were modified slightly to ensure proper functioning with MODPATH6. Modifications to the original MODFLOW models included: 1. changing IPHDRY in the UPW package so that the dry cell flag value (HDRY) was written to the binary heads (*.hds) file, 2. selecting the compact budget option to ensure proper utilization of IFACE values by MODPATH, and 3. the period length (PERLEN) was increased for one model, although it has [...]
