Head Sluice: The Head-sluice (Kūṛṛan-vay), as we understand from the Pallava records, is a sort of regulator. It is usually a strong masonary work at a point where the canal takes off from a river or tank; and its purpose here is to control the supply entering the canal. Muka-vāy, talai-vāy, vāyt-talai are the other terms in Tamil to be identified with the head-sluices (SII, I, 151; EI; V p. 49). Above the head-sluice was constructed a ‘head of water’ (uvantri or taluippelai) with a large mouth or opening which conveyed the excess flow of water entering the canal from the main sluice (SII, II. No. 93, p. 11; III, p. 530).
