摘要
将床沙中值粒径d50=0.131～01125mm和d40>0.031mm的海岸定义为粉沙质海岸,指出粉沙质海岸泥沙运动的特点为:泥沙活跃,易悬易沉,运移型态为悬移质和推移质共存,易发生强淤或骤淤。
A definition of silt-sandy beach has been defined as 0.1031 mm〈d50〈0.125mm and d40〉0.031 mm, where the characteristics of sediment movement are described as active sediment movement, easy initial movement of sand, coexistence of suspended load and bed load, as well as strong siltation and sudden siltation.
