5) scouring patterns
冲淤形态
1.
The scouring patterns of sandy bed in front of breakwaters under the action of irregular broken clapotis were investigated by experiments conducted in a wave flume on conditions of different water depths, different wave spectrum, different sand size and different seabed slop.
通过水槽试验,研究了不规则破碎波作用下不同水深、不同波谱、不同粒径和不同海床坡度情况下堤前沙质海床的冲淤形态,按照波作用和泥沙粒径的相对关系,将其分为5种类型:堤前冲刷Ⅰ型、堤前冲刷Ⅱ型、堤前冲刷Ⅲ型、堤前淤积Ⅰ型和堤前淤积Ⅱ型,并分析了各种冲淤形态的形成过程。
6) Process of Erosion and Siltation
地形冲淤演变规律
补充资料：冲场
1.亦作"冲场"。 2.戏曲名词。谓传奇剧本的第二折。冲场开头必有个长引子，引子唱完，继以诗词和骈体文的定场白，要以简单的语言，说明登场人物的身份﹑性格﹑坏境和当时的思想，并要酝酿全剧的精神，埋伏下全剧的重要节目。 3.方言。指人的外貌﹑仪表。
