Problem Statements and Purpose. Geographical cover is compound natural complex that had forming during all natural history. The complex composed by terrigenous landscapes, from one side, thalassogenic (hydrogenous) systems, from second side, and between them natural coastal global systems located as a integral result of its active interaction (contact system Land–Ocean). The aim of our article is ascertainment, estimation, analysis of coastal systems, its objects, factors, properties, morphology, inner compositions, locations in different environment of global coastal zone, as a part of Geographical Cover. Our article was estimated by integral, summarised, general theoretical. Data and Methods. In the article we are using materials of self coastal research along shores of differed tidal and non-tidal seas. For geographical comparisons, we used coastal information from datum of other authors. Methods that we applicated were: coastal descriptions and measurements, stationary researches during long period, cartographic, comparative-geographical methods, mathematical statistic. Natural material was elaborated in analytical laboratory of our cathedra. We did using with application different technique and equipment. Basical Results. During the course of natural history, the geographic cover by our entire Planet and therefore acquired the properties of a cover (jacket). In the process of development and under the impact of tectonic, gravitational and geochemical energies, it has undergone differentiation into original natural sectors. We consider them to the planetary megasystems that naturally and historically determined the initial stages of the organization of different physic-geographical systems. In the our paper, we analyze the natural genesis, forms, structures, sizes, peculiarities of coastal megasystem between the Land and Ocean objects, that was named “aquashaft megasystem”. Within the aquashaft megasystem, main elementary by abrasive (erosive), accumulative, tidal, non-tidal, biological and other conditions of a regions/sites were studied. Realized researches were aimed at improving the theory of physical geography and use of optimal utilization of a natural resources, nature management and planning of buildings also. Complex environment of a coastal zone are extremely diverse system. The megasystem are fundamentally different from the corresponding level of other megasystems: of the Land (landscape systems) and the Ocean (thalassogens). The differences can be traced primarily to the horizontal and vertical arrangement and to origin. They determine all other properties of systems of different organization levels within coastal system complex of around all long of World Ocean. These include: diverse acting factors (wind, windy waves, tidal, anebary, wave and tidal currents, ice, et. al.), energy and matter flows, external form, internal structure, sedimentary substrate quality, geochemical factors, biological characteristics, sediment composition, forms and magnitudes of dynamism at the level of individual taxon, geographical facies and processes. Facial objects, processes and natural mechanisms are very important for understanding of geographical facies and regions, for defining tracts, harmonious aggregates of tracts for defining localities, aggregates of localities for defining natural geographical systems from highest to elementary levels by different environments of land, coastal zone and in the World Ocean opened part. Without taking into account the planetary distribution, origin, acting factors, energy types, processes, structure of elements, external features, structure of individual natural systems, without the peculiarities of their interaction in different natural conditions and during different periods, it is impossible to develop a general theory of physical geography and all geography in total. As I am looking, in future the next step will be in development the geographical sciences for active accurate documentation of each taxon, facies and so on, according to hierarchical rows of the Land, the Coastal System and the Ocean (the water column and the seabed). It is very important further geographical systematization along the entire relevant hierarchical series.
