They are both free of spurious elevation modes, have good dispersive properties and have a relatively low computational cost. In this paper, we derive both finite element schemes in the same unified framework and discuss their respective qualities in terms of conservation, consistency, propagation factor and convergence rate. We also highlight the impact that the local variables placement can have on the model solution. The main conclusion that we can draw is that the choice between elements is highly application dependent. We suggest that the <i>P<sup>NC</sup><sub>1</sub></i> - <i>P<sub>1</sub></i> element is better suited to purely hydrodynamical applications while the <i>RT<sub>0</sub></i> element might perform better for hydrological applications that require scalar transport calculations.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A tale of two elements: <i>P<sup>NC</sup><sub>1</sub></i> - <i>P<sub>1</sub></i> and <i>RT<sub>0</sub></i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:01.897972","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Shallow water equations; Finite element method; Propagation factor; Consistency","OtherDescriptors":null,"Notes":null,"AnaPub":2009,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2012-06-14","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000265400800004","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.ocemod.2008.07.002"},"refs":null,"anarec":{"AnaID":216164,"PubliDate":2009,"Pagination":"24-33","XtraPublOfAnaID":null,"ISBN":null,"Volume":"28","Issue":"1-3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45570,"SerRR":"Ocean Modelling.
