- An alluvial megafan is a large cone or fan-shaped deposit built up by complex deposition patterns of stream flows originating from a single source point known as an apex. Megafans differ from Alluvial fans in their sheer size. Due to their larger size, they may be formed by different geomorphic processes. The criterion of what differentiates megafans from typical alluvial fans is an artificial one of scale. The scale divide varies in the literature, with the most common being a 100-km apex-to-toe length. Alternative values as little of 30-km apex-to-toe length have been proposed, as well as alternative metrics like coverage areas of greater than 10,000 square-km. (en)
- 巨型扇沉積（英語：megafan）是一種大型扇形沉積，是由大型河流穿越山地抵達平原時，流速降低攜帶的砂石大量堆積形成的，從扇頂到扇底的長度一般超過100公里。 (zh)
