Abstract The most important design index of water intakes is critical submergence depth the intake. at which air core formed by vortex about to enter emergence a and entry into intake increase head loss decrease discharge coefficient. reservoir geometric asymmetry, presence unevenness in bottom angle approach flow are among factors that influence formation depth. In this research, physical mode...
