Some of these methods can be applied to monitor pumping tests to identify fractures contributing to groundwater flow and, with this, determine hydraulic conductivity and transmissivity along the well. We present a procedure to identify fractures contributing to groundwater flow using spontaneous potential measurements generated by electrokinetic processes when the borehole water head is lowered and then monitored while recovering. The electrokinetic model for flow through a tabular gap is used to interpret the measured data and determine the water head difference that drives the flow through the fracture. We present preliminary results at a test site in crystalline rocks on the campus of the University of S\u00e3o Paulo.<\/jats:p>","DOI":"10.1111\/gwat.13009","type":"journal-article","created":{"date-parts":[[2020,4,19]],"date-time":"2020-04-19T10:19:29Z","timestamp":1587291569000},"page":"16-23","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Fracture Flow Characterization with Low\u2010Noise Spontaneous Potential Logging"],"prefix":"10.1111","volume":"59","author":[{"given":"Andr\u00e9 C.G.","family":"Kowalski","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlos A.","family":"Mendon\u00e7a","sequence":"additional","affiliation":[{"name":"Department of Geophysics University of S\u00e3o Paulo, Rua do Mat\u00e3o, 1226, S\u00e3o Paulo, Brazil; 05508\u2010090"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ulrich S.","family":"Ofterdinger","sequence":"additional","affiliation":[{"name":"School of Natural and Built Environment Queen's University Belfast, David Keir Building, Stranmillis Road, Northern Ireland, UK; BT9 5AG"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,5,11]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jappgeo.2016.01.021"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1745-6584.2011.00798.x"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jenvman.2017.04.033"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/gwat.12064"},{"key":"e_1_2_9_6_1","unstructured":"Keys W.S.1990.
