对来自micro-CT扫描的3D絮凝物数据进行体积分割。对分割的体积进行量化，以从絮凝物结构中提取孔隙度和几个孔隙空间参数。絮凝悬浮沉积物（絮凝物）存在于全球各种环境中，其运输和行为对渔业、水产养殖和航运等几个行业具有重要意义。此外，它们行为的建模对于河口和沿海洪水预测和防御非常重要，絮凝过程发生在其他不相关的行业，如造纸和化工生产。絮凝体孔隙度通常使用推断间接或代用数据方法进行评估。这些方法低估了絮体孔隙率%由c。30%，并且无法测量这些孔隙空间和网络的微观复杂性，从而使模型的输入次优。本研究介绍了一种新的三维孔隙度和孔隙空间定量协议，产生直接量化的孔隙率%和孔隙空间数据。
3D floc data from micro-CT scanning is segmented volumetrically This segmented volume is quantified to extract porosity and several pore space parameters from the floc structure Flocculated suspended sediments (flocs) are found in a variety of environments globally, and their transport and behavior bear substantial importance to several industries including fisheries, aquaculture, and shipping. Additionally, the modelling of their behavior is important for estuarine and coastal flood prediction and defence, and the process of flocculation occurs in other unrelated industries such as paper and chemical production. Floc porosity is conventionally assessed using inferential indirect or proxy data approaches. These methods underestimate floc porosity % by c. 30% and cannot measure the micro-scale complexity of these pore spaces and networks, rendering inputs to models sub-optimal. This study introduces a novel 3D porosity and pore space quantification protocol, that produces directly quantified porosity % and pore space data.
