Tailrace refers to the channel or tunnel that carries water from the turbine after it has passed through a hydroelectric power plant. There are several synonyms for the word, including outflow, discharge channel, spillway, exit channel, and effluent. The term tailrace is commonly used in the context of hydropower generation, whereas other synonyms such as spillway and outflow may be used in more general water management scenarios. The tailrace is an important component of any hydroelectric facility, as it ensures that the water is safely and efficiently returned to its natural environment after being used to produce electricity.
