Secondary Sediment Cell Point

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，其内部海洋与陆地地貌通过沉积物交换过程相互关联，通常采用沉积物收支（sediment budgets）进行描述。它们包含沉积物供给区（源，sources）、沉积物损失区（汇，sinks），以及连接上述区域的沉积物输运过程（路径，pathways）。沉积物输运路径涵盖沿岸与跨岸过程，因此沉积物单元以二维形式呈现最为适宜。沉积物单元是具有物理基础的天然管理单元，且常跨越行政边界。更多信息可访问以下网站获取：http://www.transport.wa.gov.au/imarine/coastal-erosion-and-stability.asp
