CSDMS Summer Science Series II: Modelling of interactions between bioturbation and mud distribution reveals effects on large-scale estuarine morphology
Macrobenthic species that live within or on top of estuarine sediments can destabilize local mud deposits through bioturbating activities. The resulting enhanced sediment availability will affect large-scale morphological change. We numerically model two contrasting bioturbating species by means of our novel literature-based eco-morphodynamic model. We find significant effects on local mud accumulation and bed elevation change leading to a large-scale reduction in deposited mud. In turn, the species-dependent mud content redefines their habitat and constricted species abundances. Combined species runs reveal a new ecological feedback facilitating survival of the dominant species as a result of combined eco-engineering activity.
