The only river that  flows through the Nagaur district is the Luni which is of ephemeral nature. This river originates from the Aravallis, near Pushkar in Ajmer district and follows a WSW course into the Kutch.

Although it has a number of tributaries all but one join it from the south. None of these drain any water into the main river but for a few days during the monsoon . The wide beds of these rivers have been considerably filled by alluvial and aeolicin sediments and in places they have almost been choked by aeolian sand. The river Luni also acts as an barrier against the eastward spread of aeolian sand. The study area is greatly influenced by strong winds and the soil is wind-modified to a varied degree. The effect of arid condition is reflected in the lack of horizonatioi of the soils. The soil material appears to have been formed from mixed sources of igneous, metamorphic and vindhyan systems.
