Chapter Three Tidal Flats

摘要: Publisher Summary Tidal flats are commonly associated with enclosed or sheltered bay deposits, as well tide-dominated estuarine and deltaic channels, open-coast estuarine, lagoonal plains, backshore plains in wave-dominated settings. They largely dependent on processes for sediment supply. significant spatial temporal variations facies across subtidal to supratidal zones ranging from a generally low-energy shoreface through intertidal mudflats sand vegetated platforms cut by deeper tidal channels. These shores cannot be easily defined, therefore, terms of morphological sedimentary categories because the diversity their morphology composition. While characteristic “muddy” composition is dominant feature flats, size not accounted classical energy considerations wave power forcing, although such dominantly occupy lower-energy part spectrum. Sediment conditioned locally available supply terrestrial catchments. This chapter focuses three topics: (1) sandflats; (2) versions, mangroves, saltmarshes; (3) palaeoenvironmental shore processes.
