Deltaiska
Deltaiska is a term used in theoretical geography and sedimentology to describe a proposed class of river delta systems characterized by rapid, episodic avulsions, high sediment flux, and strong interactions between subsidence and shoreline mobility. The concept is intended as an analytical model for understanding complex deltaic morphologies rather than a single, named real-world delta. Etymology: the word combines delta, from the river-mouth feature, with the suffix -iska, used in some European languages to form thematic adjectives, signaling a category within deltaic forms.
Key features commonly associated with deltaiska systems include frequent channel avulsions, the rapid growth of multiple
Classification within deltaiska is hypothetical and often proposed as a continuum: Type I emphasizes high sediment
