Smooth parts of numerical solutions have small absolute values of weak local residuals. Rougher parts of numerical solutions have larger absolute values of weak local residuals. This behaviour enables the weak local residuals to detect parts of numerical solutions which are smooth and rough (non-smooth). Weak local residuals that we formulate are implemented successfully as refinement or coarsening indicators for adaptive mesh finite volume methods used to solve shallow water equations.<\/jats:p>","DOI":"10.3390\/sym12030345","type":"journal-article","created":{"date-parts":[[2020,3,2]],"date-time":"2020-03-02T07:50:53Z","timestamp":1583135453000},"page":"345","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Weak Local Residuals as Smoothness Indicators in Adaptive Mesh Methods for Shallow Water Flows"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5319-9744","authenticated-orcid":false,"given":"Sudi","family":"Mungkasi","sequence":"first","affiliation":[{"name":"Department of Mathematics, Faculty of Science and Technology, Sanata Dharma University, Yogyakarta DIY 55281, Indonesia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6730-3108","authenticated-orcid":false,"given":"Stephen Gwyn","family":"Roberts","sequence":"additional","affiliation":[{"name":"Mathematical Sciences Institute, College of Science, The Australian National University, Canberra, ACT 2600, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,3,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Lee, S.
