The hypothesis is that coarser sediments will allow a greater \nportion of upward-flow to flow around the meter instead of through it. The hypothetical model \nsimulates upward flow through unconsolidated sediments in the Seepage Meter Calibration \nTank operating at the Denver Federal Center in Lakewood, Colorado. Groundwater Vistas \n(version 7) was used for initial development of the hypothetical model and postprocessing. \nExecutables and input files were then ported into this archive with public domain executables. \nThe particle-tracking program, MODPATH (version 5), is used to visualize flow through and \naround a seepage meter in sediments with conductivities ranging from 0.01 m/d to 100 m/d. \nFifteen steady-state scenarios are simulated: three different insertion depths (6-cm, 11-cm, \nand 16-cm to bottom of hydrologic flow barriers that represent the wall of the Seepage Meter) \nfor each of five conductivities (Kall ,Ky, Kz = 0.01, 0.1, 1.0, 10, and 100 m/d). Volumes of flow \nboth inside and outside of the Seepage Meter are calculated with Zonebudget (version 3) and \nthese volumes are presented in the workbook \\ancillary\\Seep95.xlsx of this data release.  The \nconceptualization and discretization of the numerical model are described in the journal article \n(https://doi.org/10.3390/w12113267). This USGS data release contains all the input and output \nfiles for the simulations described in the associated journal article \n(https://doi.org/10.3390/w12113267).
