桑迪土壤干燥时通常是防水的。在斜坡地区，这可能导致地表径流和侵蚀。土壤的拒水性可以用难以测定的固液接触角来分类。另一种方法是水滴穿透时间。这种方法不仅更容易应用，而且提供了一个更有用的分类尺度。此外，它与侵蚀危害直接相关，因为径流取决于雨滴渗透所需的时间。荷兰海岸沿着沙丘土壤中的接触角和水滴穿透时间之间存在密切关系。
Sandy soils are often water repellent when dry. In sloping areas this may result in surface runoff and erosion. Water repellency in soils can be classified with the solid-liquid contact angle which is difficult to determine. Another method is the water drop penetration time. This method is not only easier to apply but provides a more useful scale for classifying water repellent soils. Moreover, it is directly related to erosion hazard because runoff depends on the time required for the infiltration of rain drops. A close relationship was found between the contact angle and the water drop penetration time in dune soils along the coast of the Netherlands.
