| Research Abstract |
We examined relationships between hydrodynamic conditions and sediment properties in subtropical, coastal soft-bottom habitats, and further proposed a mechanistic model for physical processes responsible for non-linearity of the relationships. We also found that coastal sediment properties reflect watershed environment in estuarine sites at which depositional processes dominantly control sediment properties. Based on our findings, we propose a guideline listing points which managers should take account of to properly manage coastal soft-bottom habitats.
