The Khasa River (Arabic: نهر خاصة, Kurdish: ڕووباری خاسە) is a winterbourne river which runs through the city of Kirkuk in northern Iraq. It dries up completely in the summer but turns into a raging river in the winter, flooding its banks at times as happened in the 1950s. The river has symbolic value to the city's inhabitants. It is one of the tributaries of the Tigris River. [1]
