Müller, Sascha 2020 Journal article Water vol.12, no.11 Basel, Switzerland MDPI https://doi.org/10.3390/w12113267 A three-dimensional finite-difference model, MODFLOW-2005 (version 1.12.00), was developed to better understand how Seepage Meter efficiency changes when installed in sediments with wide range of conductivities. The hypothesis is that coarser sediments will allow a greater portion of upward-flow to flow around the meter instead of through it. The hypothetical model simulates upward flow through unconsolidated sediments in the Seepage Meter Calibration Tank operating at the Denver Federal Center in Lakewood, Colorado. Groundwater Vistas (version 7) was used for initial development of the hypothetical model and postprocessing. Executables and input files were then ported into this archive with public domain executables. The particle-tracking program, MODPATH (version 5), is used to visualize flow through and around a seepage meter in sediments with conductivities ranging from 0.01 m/d to 100 m/d. Fifteen steady-state scenarios are simulated: three different insertion depths (6-cm, 11-cm, and 16-cm to bottom of hydrologic flow barriers that represent the wall of the Seepage Meter) for each of five conductivities (Kall ,Ky, Kz = 0.01, 0.1, 1.0, 10, and 100 m/d). Volumes of flow both inside and outside of the Seepage Meter are calculated with Zonebudget (version 3) and these volumes are presented in the workbook \ancillary\Seep95.xlsx of this data release. The conceptualization and discretization of the numerical model are described in the journal article (https://doi.org/10.3390/w12113267). This USGS data release contains all the input and output files for the simulations described in the associated journal article (https://doi.org/10.3390/w12113267). MODFLOW-2005 (version 1.12.00) and MODPATH (version 5) were used to better understand the effect of insertion depth and permeability on Seepage Meter efficiency. This USGS data release contains all the executables, input and output files needed to reproduce the results presented in the section "Influence of Hydraulic Conductivity on Meter Efficiency" in the journal article (https://doi.org/10.3390/w12113267). Support is provided for correcting errors in the data release and clarification of the modeling conducted by the U.S. Geological Survey. Users are encouraged to review the jounal article (https://doi.org/10.3390/w12113267) to understand the purpose, construction, and limitations of this model. The model will run successfully only if the original directory structure is correctly restored.

A vertical conductivity (Kz) of 0.252 m/d assigned to the top 1-cm layer within the Seepage Meter met that target, and that Kz for that region was kept fixed for all scenarios. The other 14 scenarios were run with no adjustments other than changing the depth of insertion (6, 11, and 16 cm) and the conductivity in all other areas of the active domain (0.01, 0.1, 1.0, 10, and 100 m/d).

Each project is a scenario for an insertion depth (D1-D3) and a sediment conductivity (K1-K5). The insertion depth is the vertical height of the hydrologic flow barriers (HFBs) assigned to the perimeter of the seepage meter. The conductivity, Kall, is the isotropic conductivity (Kz, Ky, and Kz) to all active regions of the domain with the exception of Kz for zone 2. Vertical conductivity in zone 2, the top cm of the active domain within the simulated current meter is held constant at 0.252 m/d that simulates a seepage meter efficiency of approximately 95 percent in sediments with Kall of 1 m/d elsewhere in the domain. In addition, there is an Excel workbook that summarizes seepage volume for eah scenario for each insertion depth (D1-D3) and sediment conductivity (K1-K5). Seepage volumes through the cross-sectional area of the seepage meter (zone 2) and the area outside of the seepage meter (zone 3) are reported in files like \output\output.D1K_Modpath\ZB_D1K1.csv 81.24 https://water.usgs.gov/GIS/dsdl/gwmodels/rosenberry2020_water/ancillary.zip None 20201231 Michael Ierardi Ask USGS -- Water Webserver Team mailing
