It is scientifically agreed that sites or antiquities can be classified or described chronologically, such as prehistoric monuments or ancient Egyptian antiquities or Islamic monuments and others
They can also be categorized as regional effects such as Greece or the effects of the Arabian Peninsula
The description of the effect as a drowning effect does not fall within any of these recognized scientific classifications. For example, we do not cite the effects found in the deserts as desert traces, or those found in the mountains as mountainous effects, in relation to their location. Not only that, but the location of the existence of the same effect may change from one period to another due to many natural and human factors, which makes the description of the site or classification in relation to the location of the existence of an unscientific and immutable description. We find, for example, that the traces of the ancient nub were considered to be partially overwhelmed before they were moved to their present place
On the other hand, natural factors such as sea level change, sedimentation or erosion may alter the nature of the place where the archaeological site is located. For example, we find that some of the ports on the shores of Mariout Lake have been dry for a number of years. However, due to the high level of water in the lake due to agricultural drainage, these sites became completely flooded with water in the winter season. In the summer, The evaporation leads to a drop in the level of water, so that the sidewalks dry again
Therefore, the classification of archaeological sites according to their location does not constitute a particular scientific classification and that the location may change due to several circumstances
Over the last fifty years, which have developed and developed the methods and techniques of research and archaeological work in submerged sites, the term "sunken effects" was closely related to "marine archeology" and described archaeological remains as "Maritime Archeology"
Is in fact a qualitative description, that is, those archaeological remains, is the product of the relationship of man over the ages with different surfaces and waterways
Thus, marine archeology has emerged as a branch or field of archeology, where it deals with the study of all archaeological remains of marine nature. The pictures of marine antiquities include boats, ships and all related designs, equipment, construction, use and navigation. As well as various marine and coastal installations such as berths, ports and shipyards
But many marine archaeological sites are located in dry areas or far from the coastal environment. For example, ships or boats found buried in a desert environment, such as the Khufu funerary vessel, the Dahshur and Abidus boats, whether of funerary, religious or ritual nature, were constructed in the same manner and technique. Those ages, therefore, are seen as traces of freedom and if not soaked. We can also see other images of undersea marine relics in a number of Egyptian ports on the Red Sea coast during the Roman era. They have now become hundreds of meters from the seafront as a result of sedimentation over the past centuries. In addition, the sediments and sand were completely covered
Just as there are undersea effects, there are also undersea effects, either wholly or in molecules, but not of a marine nature. The dozens of statues, columns, architectural parts, coins and other artifacts found on the coast of Alexandria - both in the eastern port and in the Gulf of Abu Kir - are undoubtedly not traces of freedom
In the end we find that not all sunken effects necessarily have effects freely and not all marine relics are necessarily soaked. However, there is a great deal of overlap between the two fields of sunken effects, which at the same time are of a marine nature
