Previous in situ studies of dual\u2010domain (i.e., mobile\/less\u2010mobile porosity) systems have been limited to solute tracer injections at scales of meters to hundreds of meters and subsequent numerical model parameterization using fluid concentration histories. Pairing fine\u2010scale (e.g., sub\u2010meter) geoelectrical measurements with fluid tracer data over time alleviates dependence on flowpath\u2010scale experiments, enabling spatially targeted characterization of shallow sediment\/water interface media where biogeochemical reactivity is often high. The Dual\u2010Domain Porosity Apparatus is a field\u2010tested device capable of variable rate\u2010controlled downward flow experiments. The Dual\u2010Domain Porosity Apparatus facilitates inference of dual\u2010domain parameters, i.e., mobile\/less\u2010mobile exchange rate coefficient and the ratio of less mobile to mobile porosity. The Dual\u2010Domain Porosity Apparatus experimental procedure uses water electrical conductivity as a conservative tracer of differential loading and flushing of pore spaces within the region of measurement. Variable injection rates permit the direct quantification of the flow\u2010dependence of dual\u2010domain parameters, which has been theorized for decades but remains challenging to assess using existing experimental methodologies.<\/jats:p>","DOI":"10.1111\/gwat.12846","type":"journal-article","created":{"date-parts":[[2018,11,15]],"date-time":"2018-11-15T00:10:20Z","timestamp":1542240620000},"page":"640-646","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["The Dual\u2010Domain Porosity Apparatus: Characterizing Dual Porosity at the Sediment\/Water Interface"],"prefix":"10.1111","volume":"57","author":[{"given":"Courtney R.","family":"Scruggs","sequence":"first","affiliation":[{"name":"Earth System Processes Division U.S. Geological Survey  Hydrogeophysics Branch, 11 Sherman Place, Unit 5015, Storrs CT 06269"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"Briggs","sequence":"additional","affiliation":[{"name":"Earth System Processes Division U.S. Geological Survey  Hydrogeophysics Branch, 11 Sherman Place, Unit 5015, Storrs CT 06269"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Frederick D.","family":"Day\u2010Lewis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dale","family":"Werkema","sequence":"additional","affiliation":[{"name":"National Exposure Research Laboratory, Exposure Methods &amp; Measurement Division U.S. Environmental Protection Agency, Office of Research and Development  Environmental Chemistry Branch, Las Vegas NV 89119"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"suffix":"Jr","given":"John W.","family":"Lane","sequence":"additional","affiliation":[{"name":"Earth System Processes Division U.S. Geological Survey  Hydrogeophysics Branch, 11 Sherman Place, Unit 5015, Storrs CT 06269"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,12,13]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/2012RG000417"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/wrcr.20397"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/2014WR015880"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/2015GL064200"},{"volume-title":"Electrical geophysical data collected in the shallow sediments of Snake pond","year":"2018","author":"Briggs M.A.","key":"e_1_2_7_6_1"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1029\/2007WR006750"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/2017GL073326"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/hyp.13134"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1029\/2000WR900334"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.2307\/1352377"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/wrcr.20492"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.2134\/jeq2015.03.0151"},{"key":"e_1_2_7_14_1","doi-asserted-by":"crossref","unstructured":"Masterson J.
