View source for Drainage Class

'''Drainage Class''' is a geomorphological categorization referring to the frequency and duration of periods of saturation or partial saturation during [[soil]] formation, as opposed to altered drainage, which is commonly the result of artificial drainage or irrigation but may be caused by the sudden deepening of channels or the blocking of drainage outlets.
