Ulhas River
From Biocrawler, the free encyclopedia.
The Ulhas River is a river of western India. It originates near Karjat in the Western Ghats Range, and flows westward through Raigad and Thane districts of Maharashtra north to Ulhasnagar (to which it gives its name) and on to Kalyan, where it turns west to Thane. At Thane the river splits into two branches which flow west and south, respectively, around Salsette Island, on which lies the metropolis of Mumbai. Both branches are estuarine, and lie on seismic fault lines. The main branch turns northwestward to Ghodbunder, where it opens into the estuary of Vasai Creek. Thane Creek flows south to empty into Bombay Harbour. The estuary of the Ulhas is the site of the historical ports of Kalyan, Kopri (Chersonesus/Coprostaneum) and Shurparaka (now Sopara).
