Inland ones of these features are demonstrated near Marajó in Brazil and by the Okavango in Botswana. The Gilbert type of these are formed by coarse sediments, while erosion controls the shape of the wave-dominated type of these. These features come in arcuate, cuspate, and bird foot varieties, and their slopes are shallower than (*) alluvial fans. Belém lies near one of these, as do Rotterdam, Nanjing, Ho Chi Minh City, New Orleans, and Cairo. For ten points, name this geographic feature where rivers form a roughly triangular shape as they meet the sea, named after the fourth letter of the Gr
