A methodology for monitoring the behaviour and size of sand after a beach nourishment process is presented herein. Four sampling campaigns (before and just after the nourishment, after six months and one year later) were performed on four beaches of the Gulf of Cadiz (Spain). D₅₀ and sorting size parameters were analysed. Among the results, it should be noted that differences of up to 20% between native and nourished sand values disappear only one year after the nourishment.

海滩滋养后沉积物参数的演变

本文介绍了一种用于在海滩滋养过程之后监测沙子的行为和大小的方法。在加的斯湾（西班牙）的四个海滩上进行了四次采样活动（在营养之前和之后，六个月和一年之后）。分析了 D ₅₀和分选尺寸参数。在结果中，应该指出的是，原生沙子和滋养沙子之间高达 20% 的差异在滋养后仅一年就消失了。
