discharge. The weir provides a unique relationshipbetween the
upstream head and the discharge. Flow overa weir plunging the air
bubbles into a downstream waterpool has an impact on the amount of
dissolved oxygen ina river system (Unsal, 2010). Therefore, it is
often used inwater supply system, wastewater system, sewagesystem,
stormwater control system, and hydrologicwatershed research. There
are mainly two types of weirs:sharp-crested weirs and broad-crested
weirs.
