<P> The Thar Desert extends between the Aravalli Hills in the north - east , the Great Rann of Kutch along the coast and the alluvial plains of the Indus River in the west and north - west . Most of the desert is covered by huge shifting sand dunes that receive sediments from the alluvial plains and the coast . The sand is highly mobile due to strong winds occurring before the onset of the monsoon . The Luni River is the only river integrated into the desert . Rainfall is limited to 100 -- 500 mm ( 3.9 -- 19.7 in ) per year , mostly falling from July to September . </P>
