许多水生植物的种子以及许多繁殖体和幼虫都在水面漂浮和运输。因此，这些颗粒受到表面张力的影响，这可能会通过毛细管吸引力增强挺水植被对它们的捕获。在这项工作中，我们开发了一个半经验模型，该模型可以预测由于毛细管作用，植物茎和树枝刺穿水面，抵抗流水施加的阻力而保留漂浮颗粒的概率。还进行了特定的实验室实验来校准和验证模型。
The seeds of many aquatic plants, as well as many propagulae and larvae, are buoyant and transported at the water surface. These particles are therefore subject to surface tension, which may enhance their capture by emergent vegetation through capillary attraction. In this work, we develop a semi-empirical model that predicts the probability that a floating particle is retained by plant stems and branches piercing the water surface, due to capillarity, against the drag force exerted by the flowing water. Specific laboratory experiments are also performed to calibrate and validate the model.
