Trough

A trough is a long, narrow, open container used primarily to hold food or water for animals. Beyond its literal meaning, 'trough' can also describe a low point or period of decline in a cyclical process, such as an economic trough representing the lowest point of a recession or a wave trough being the lowest point between two crests. The shape is characterized by a concave elongated shape that has sides, making it efficient for holding things.
