Sci. Data"],"abstract":"<jats:p>Since the turn of the 21st century, image-based velocimetry techniques have become an increasingly popular approach for determining open-channel flow in a range of hydrological settings across Europe and beyond. Simultaneously, a range of large-scale image velocimetry algorithms have been developed that are equipped with differing image pre-processing and analytical capabilities. Yet in operational hydrometry, these techniques are utilised by few competent authorities. Therefore, imagery collected for image velocimetry analysis (along with reference data) is required both to enable inter-comparisons between these differing approaches and to test their overall efficacy. Through benchmarking exercises, it will be possible to assess which approaches are best suited for a range of fluvial settings, and to focus future software developments. Here we collate and describe datasets acquired from seven countries across Europe and North America, consisting of videos that have been subjected to a range of pre-processing and image velocimetry analyses (Perks et\u00a0al.,\u00a02020, https:\/\/doi.org\/10.4121\/uuid:014d56f7-06dd-49ad-a48c-2282ab10428e). Reference data are available for 12 of the 13 case studies presented, enabling these data to be used for reference and accuracy assessment.<\/jats:p>","DOI":"10.5194\/essd-12-1545-2020","type":"journal-article","created":{"date-parts":[[2020,7,8]],"date-time":"2020-07-08T13:11:44Z","timestamp":1594213904000},"page":"1545-1559","source":"Crossref","is-referenced-by-count":84,"title":["Towards harmonisation of image velocimetry techniques for river surface velocity observations"],"prefix":"10.5194","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6960-5484","authenticated-orcid":false,"given":"Matthew T.","family":"Perks","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"},{"role":"corresponding-author","vocabulary":"crossref"}]},{"given":"Silvano Fortunato","family":"Dal Sasso","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandre","family":"Hauet","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizabeth","family":"Jamieson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1243-6955","authenticated-orcid":false,"given":"J\u00e9r\u00f4me","family":"Le Coz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7428-4793","authenticated-orcid":false,"given":"Sophie","family":"Pearce","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8598-0295","authenticated-orcid":false,"given":"Salvador","family":"Pe\u00f1a-Haro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7242-6559","authenticated-orcid":false,"given":"Alonso","family":"Pizarro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8291-900X","authenticated-orcid":false,"given":"Dariia","family":"Strelnikova","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5176-3492","authenticated-orcid":false,"given":"Flavia","family":"Tauro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James","family":"Bomhof","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5715-106X","authenticated-orcid":false,"given":"Salvatore","family":"Grimaldi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alain","family":"Goulet","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Borb\u00e1la","family":"Hortob\u00e1gyi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Magali","family":"Jodeau","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sabine","family":"K\u00e4fer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert","family":"Ljubi\u010di\u0107","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5072-8700","authenticated-orcid":false,"given":"Ian","family":"Maddock","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Mayr","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5919-6912","authenticated-orcid":false,"given":"Gernot","family":"Paulus","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lionel","family":"P\u00e9nard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leigh","family":"Sinclair","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0225-144X","authenticated-orcid":false,"given":"Salvatore","family":"Manfreda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3145","published-online":{"date-parts":[[2020,7,8]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","unstructured":"Adrian, R.\u00a0J.: Scattering particle characteristics and their effect on pulsed laser measurements of fluid flow: speckle velocimetry vs particle image velocimetry, Appl.
