A bedform is a geological feature that develops at the interface of fluid and a moveable bed, the result of bed material being moved by fluid flow. Examples include ripples and dunes on the bed of a river. Bedforms are often preserved in the rock record as a result of being present in a depositional setting. Bedforms are often characteristic to the flow parameters, and may be used to infer flow depth and velocity, and therefore the Froude number. (en) Le forme di fondo sono conformazioni del letto di un fiume o - più in generale - di un corso d'acqua che si formano come conseguenza del movimento e della deposizione del materiale solido trasportato dal flusso idrico. Tali forme vengono determinate da vari parametri idrologici del corso d'acqua stesso tra i quali la sua profondità, la velocità di scorrimento e il numero di Froude. Il termine inglese, ripple, può anche essere reso con l'italiano increspatura. (it) 底形（英語：bedform）是一種在流體在底界面處形成的結構。是由於流體流動水底沉積物而造成的。 例如同波痕和沙丘。 底形通常被保留在岩石中，故可用於推斷流體深度和速度。 (zh) |
