持水能力（WHC）一词长期以来一直被用来帮助研究人员确定土壤对降雨下典型湿润的反应。然而，WHC 一词不足以作为描述土壤如何响应洪水事件的衡量标准。本文旨在提出一种新的 WHC 测试方法，该方法还结合了饱和条件下土壤的体积变化、剪切强度、耐侵蚀性和导水率。这些参数的定性组合将用于概述土壤抵御洪水的能力，或其“防洪能力”。本文介绍了最近使用堆肥和饮用水处理中回收的矿物质来改良土壤以提高其“防洪能力”（FHC）的测试数据，以强调单独使用 WHC 的缺点。在这个研究阶段，防洪能力的概念还只是概念性的，但是利用这些实验数据来检验防洪能力的前提。
The term water holding capacity (WHC) has long been used to help researchers determine how soils respond to typical wetting under rainfall. However the term WHC is insufficient as a measurement to describe how soil responds to flooding events. This paper aims present a novel method for WHC testing that also incorporates the volume change, shear strength, erosional resistance and hydraulic conductivity of the soil under saturated conditions. The qualitative combination of these parameters will be used to outline a soil’s ability to withstand flooding, or its ‘flood holding capacity’. Data from recent testing that uses both compost and recycled minerals from the treatment of drinking water to amend soil to improve its ‘flood holding capacity’ (FHC) is presented in this paper to highlight the shortcomings of using WHC alone. At this stage of research the idea of flood holding capacity is only conceptual, however the premise of flood holding capacity is examined using this experimental data.
