A wide variety of schemes for classifying coasts has been suggested-numerical, descriptive and genetic-but in many cases it is as difficult to remember the results of the classification as the individual land-forms. In the past, the most commonly used classification was that proposed by D.W. Johnson, who recognized four categories of shoreline:
(a) shorelines of submergence;
(b) shorelines of emergence;
(c) neutral shorelines, where the exact form is due to neither emergence nor submergence, but to a new constructional or tectonic term, such as a delta or a fault; and
(d) compound shorelines, including all shorelines which have an origin combining at least two of the preceding classes.
Johnson's is a simple genetic classification, but places heavy emphasis on one factor, sea-level change, and requires that we know something about the past history of the coast-line. Strictly speaking, nearly all shorelines are confound. A more recent and potentially much more useful scheme is that proposed by J.L. Davies on the basis of energy environments. 0n a world map he recognizes
(a) storm wave environments, where destructive storm breakers are frequent and shingle beaches are common;
(b) swell environments, which are characterized by flat constructional wave; and
(c) protected environments, the low-energy conditions of enclosed or partially enclosed seas.
It is also possible to apply the concept of differing energy environments on a wider scale.
Locals hypothesize that the legacy of Italian blood and culture in Cologne, colonized by the Romans more than 1500 years ago, makes the people more jovial and lighthearted. Cologne is the largest city on the Rhine.
