Sažetak
Beach feeding has become one of the most popular approaches to coastal engineering over the past decade and many see it as the ultimate saviour, both for increased coastal defence and for tourism. There are two aims of this research: to analyze the change of particle size distribution and grains shape after nourishment and to analyze how shape of crushed limestone aggregate can be improved before beach nourishment to become more comfortable. For this purpose, 13 samples from different parts of an artificial hotel's beach located at Split (Adriatic Sea) were taken and analyzed almost two years after filling the beach with the crushed limestone with coarser grains (16 – 31.5 mm) mixed with the same size river pebbles. The particle size distribution and shape index were analysed for all samples. Also, a few samples of the crushed limestone were taken from the quarry, where the material was taken for beach nourishment. In order to improve grains shape, these samples were subjected to abrasion, by mixing in a laboratory pan mixers or in a ball mill. The particle size distribution and shape index were then analyzed and compared with results obtained on samples from the beach. Shape of crushed aggregate can be improved by the methods of abrasion. For the purpose of beach nourishment this could be too expensive, but the power of the waves to create shape of aggregate before beach filling can be useful for this goal.
