Submerged plants with long, flexible leaves or stems are commonly found in many aquatic environments, including rivers, lakes and coastal marine waters. These plants make many significant contributions to the ecological health and water quality of their environments, including acting as sanctuary habitats, sources of food, capturing and storing particulates, reducing bed sediment erosion and turbidity. Using the engineering terminology, the aquatic plants can be defined as composite, anisotropic, viscoelastic, highly heterogeneous structures. Living in flowing waters, aquatic plants experience complex loads which are often presented by a mixture of tension, compression, bending, torsion and shear. The complex and scale dependent fluid-plant interactions are still not well understood. In particular, there are many gaps in the current knowledge related to drag-generating and drag control mechanisms.

具有长而柔韧的叶子或茎的沉水植物常见于许多水生环境中，包括河流、湖泊和沿海水域。这些植物对其环境的生态健康和水质做出了许多重大贡献，包括充当保护区栖息地、食物来源、捕获和储存颗粒物、减少床沉积物侵蚀和浑浊度。使用工程术语，水生植物可以被定义为复合的、各向异性的、粘弹性的、高度异质的结构。生活在流水中的水生植物承受着复杂的载荷，这些载荷通常由拉力、压缩力、弯曲力、扭转力和剪切力的混合形式呈现。复杂且依赖于规模的流体设备相互作用仍然没有得到很好的理解。特别是，当前与阻力生成和阻力控制机制相关的知识存在许多空白。
