The number of possible equilibria and their stability strongly depend on the forcing conditions and geometry considered. This is illustrated by considering a rectangular double-inlet system forced by <i>M</i><sub>2</sub> tidal constituents only. Depending on the <i>M</i><sub>2</sub> amplitudes and phases at both entrances, no equilibrium, one equilibrium or multiple morphodynamic equilibria may exist. In case no equilibrium is found, the minimum water depth becomes zero somewhere in the system, reducing the double-inlet system to two single-inlet systems. In the other cases, the location of the minimum water depth and the direction of the tidally-averaged sediment transport, as well as their actual values, depend strongly on the <i>M</i><sub>2</sub> tidal characteristics. Such parameter sensitivity is also observed when including the residual and <i>M</i><sub>4</sub> forcing contributions to the water motion, and when allowing for width variations. This suggests that, when considering a specific system, the number and stability of morphodynamic equilibria, as well as the characteristics of these quantities, can only be assessed by investigating that specific system in detail. As an example, the Marsdiep-Vlie inlet system in the Dutch Wadden Sea is considered. It is found that, by using parameter values and a geometry characteristic for this system, the water motion and bathymetry in morphodynamic equilibrium are qualitatively reproduced. Also the direction and order of magnitude of the tidally-averaged suspended sediment transport compare well with those obtained from a high-complexity numerical model.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Morphodynamic equilibria in double-inlet systems: existence and stability","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-22 01:32:25.325562","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"double inlet systems; tidal basins; process-based models; morphodynamic equilibria; bifurcations","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2022-06-27","DateCreate":"2022-06-23","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000757163400006","VABBcode":null,"OpenAcc":1,"DOI":"10.1029/2021JF006266"},"refs":null,"anarec":{"AnaID":352993,"PubliDate":2021,"Pagination":"e2021JF006266","XtraPublOfAnaID":null,"ISBN":null,"Volume":"126","Issue":"12","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":272091,"SerRR":"Journal of Geophysical Research-Earth Surface.
