Tertiary Sediment Cell Boundary

Sediment cells are spatially discrete areas of the coast within which marine and terrestrial landforms are likely to be connected through processes of sediment exchange, often described using sediment budgets. They include areas of sediment supply (sources), sediment loss (sinks), and the sediment transport processes linking them (pathways). Sediment transport pathways include both alongshore and cross-shore processes, and therefore cells are best represented in two-dimensions. They are natural management units with a physical basis and commonly cross jurisdictional boundaries.

沉积物单元（Sediment cells）是海岸带内空间离散的区域，在此区域内海洋与陆地地貌可通过沉积物交换过程实现相互关联，此类单元通常借助沉积物收支（sediment budgets）进行刻画。其包含沉积物供给区（sources）、沉积物流失区（sinks）以及连接上述二者的沉积物输运过程（pathways）。沉积物输运路径涵盖沿岸输运与横岸输运两类过程，因此沉积物单元的最佳表征形式为二维空间。此类单元属于具备物理基础的天然管理单元，且通常会跨越行政管辖边界。更多相关信息可通过以下网址获取：http://www.transport.wa.gov.au/imarine/coastal-erosion-and-stability.asp
