列举了涉及海湾、河口航道、小型港池、码头和码头等潮汐水体中粘性沉积物的典型工程应用。已经提到了水库和淤泥质海岸环境中的问题。河口沉积预测技术包括现场方法、物理和数值模拟以及最佳结合物理和数值模拟方法的混合模拟。在许多情况下，简单的零维建模可以产生可接受精度的结果。最近开发了三维数值模型，用于分析复杂的水流结构和相关泥沙运动无法简化的情况。通过更好地了解粘性沉积物行为的基本规律，并通过开发新的数据收集战略和仪器，可以在提高沉积速率预测准确性方面取得进一步进展。
Typical engineering applications involving cohesive sediments in tidal water bodies including bays, estuarial navigation channels, small harbor basins, piers, and wharves have been cited. Reference has been made to problems in reservoirs and in the muddy coast environment. Techniques for prediction of estuarial sedimentation include field methods, physical and numerical modeling, and hybrid modeling which optimally combines physical and numerical modeling approaches. In many cases simple, zero‐dimensional modeling yields results of acceptable accuracy. Three‐dimensional numerical models have recently been developed for analyzing situations in which the complex structure of flows and associated sediment motion cannot be simplified. Further progress in improving the accuracy of prediction of sedimentation rates can be made by better understanding the basic laws governing cohesive sediment behavior, and by developing new strategies and instrumentation for data collection.
