👉 Vallecula, also known as a valley or valleylet, is a term used in geography and geology to describe the steepening of landforms due to the accumulation of water from rivers. A valleylet is defined by two or more valleys that are connected by streams or other watercourses. The steepness of a valley can be caused by various factors such as the size and shape of the valleys, the depth of the underlying soil, and the amount of sediment collected during the accumulation process
