the pervious part of the channel shoring in the tail water of a spillway, usually designed to connect a water apron with the channel and to protect the channel from erosion; it sometimes also serves to damp pulsations and to equalize and reduce the velocities of the water flow. The part of the apron that abuts the water apron is in the form of a thick cover of individual concrete slabs and blocks, concrete and reinforced-concrete revetments (slabs connected by a flexible reinforcement), or cribs filled with rock. The end part is made of more pliant elements, such as gabions, fascines, and rock fill.
What does it mean when you dream about an apron?
Aprons were formerly associated with certain masculine occupations such as blacksmithing, but in contemporary society they are almost always associated with the kitchen and the female domestic sphere: mother, home and cooking. Apron strings have the less positive connotations of being “tied” to the home, one’s mother, or wife.
