Absetzgebiete

Absetzgebiete are areas where sediment has accumulated. This deposition occurs when a transporting medium, such as water or wind, loses its energy and can no longer carry its suspended load. In fluvial environments, absetzgebiete are commonly found in areas of decreasing water velocity, like the inside bends of rivers, at the mouths of rivers where they enter larger bodies of water (deltas), or behind obstructions. In marine settings, they form where ocean currents slow down or in sheltered areas like bays and lagoons. Aeolian absetzgebiete, or deserts, result from wind deposition of sand and dust. These deposits can range in size from fine silt to coarse gravel, and their formation is a fundamental process in shaping landscapes and creating sedimentary rock layers over geological time. The nature of the deposited material and the depositional environment dictate the characteristics of the absetzgebiete.
