Mighty Tempestuous River
A look at the map of the Indo-Gangetic Plains would make it quite obvious that a vast expanse of the land between the Yamunā and Satluj rivers is a parched realm of sandy plain bereft of the bounty of rivers (Fig. 1.1). In this riverless land the annual rainfall is no more than 15–50 cm. Compounding the problem of pervasive aridity, droughts visit the region at an interval of 2–5 years.
