Time-series of video observations of the sea bottom on the Ebro delta coast were analysed in order to estimate the bottom roughness associated with physical and biological morphological components and the sediment reworking rates caused by epifaunal organisms. Biological roughness was mainly caused by ophiuroids and tanatocenosis of bivalve and gastropod shells, which changed their abundance during the study period. The total biological roughness (K<sub>bio</sub>) ranged between 0.27 and 0.81 cm and represented a significant part (<20%) of the total form drag roughness. Flattening of ripples caused by bioturbation was observed under low-energy conditions. Surface sediment perturbation and bioturbation rates were also estimated. Based on these observations a wave propagation model was applied in order to carry out a sensitivity analysis of the significance of biological roughness on wave dissipation in the study area under different wave conditions.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Alteration of bottom roughness by benthic organisms in a sandy coastal environment","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-01 01:32:02.644202","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Biological roughness Reworking rates Ripples destruction Wave dissipation","OtherDescriptors":null,"Notes":null,"AnaPub":2008,"MonPub":null,"DateUpdate":"2020-04-17","DateCreate":"2020-04-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000260239400003","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.csr.2008.05.003"},"refs":null,"anarec":{"AnaID":323445,"PubliDate":2008,"Pagination":"2382-2392","XtraPublOfAnaID":null,"ISBN":null,"Volume":"28","Issue":"17","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42769,"SerRR":"Continental Shelf Research.
