context_page_description: Lothal was one of the southernmost cities of the ancient Indus Valley Civilization, located in the Bhāl region of the modern state of Gujarāt. Construction of the city began around 2200 BCE. Discovered in 1954, Lothal was excavated from 13 February 1955 to 19 May 1960 by the Archaeological Survey of India, the official Indian government agency for the preservation of ancient monuments. According to the ASI, Lothal had the world's earliest known dock, which connected the city to an ancient course of the Sabarmati river on the trade route between Harappan cities in Sindh and the peninsula of Saurashtra when the surrounding Kutch desert of today was a part of the Arabian Sea. However, this interpretation has been challenged by other archaeologists, who argue that Lothal was a comparatively small town, and that the "dock" was actually an irrigation tank. The controversy was finally settled when scientists from The National Institute of Oceonography, Goa discovered foraminifera and salt, gypsum crystals in the rectangular structure clearly indicating that sea water once filled the structure.
context_section_description: While the wider debate over the end of Indus civilisation continues, archaeological evidence gathered by the ASI appears to point to natural catastrophes, specifically floods and storms as the source of Lothal's downfall. A powerful flood submerged the town and destroyed most of the houses, with the walls and platforms heavily damaged. The acropolis was levelled (2000–1900 BCE), and inhabited by common tradesmen and newly built makeshift houses. The worst consequence was the shift in the course of the river, cutting off access to the ships and dock. The people built a new but shallow inlet to connect the flow channel to the dock for sluicing small ships into the basin. Large ships were moored away. Houses were rebuilt, yet without removal of flood debris, which made them poor-quality and susceptible to further damage. Public drains were replaced by soakage jars. The citizens did not undertake encroachments, and rebuilt public baths. However, with a poorly organised government, and no outside agency or central government, the public works could not be properly repaired or maintained. The heavily damaged warehouse was never repaired properly, and stocks were stored in wooden canopies, exposed to floods and fire. The economy of the city was transformed. Trade volumes reduced greatly, though not catastrophically, and resources were available in lesser quantities. Independent businesses caved, allowing a merchant-centric system of factories to develop where hundreds of craftsmen worked for the same supplier and financier. The bead factory had ten living rooms and a large workplace courtyard. The coppersmith's workshop had five furnaces and paved sinks to enable multiple artisans to work.
  The declining prosperity of the town, paucity of resources and poor administration increased the woes of a people pressured by consistent floods and storms. Increased salinity of soil made the land inhospitable to life, including crops. This is evidenced in adjacent cities of Rangpur, Rojdi, Rupar and Harappa in Punjab, Mohenjo-daro and Chanhudaro in Sindh. A massive flood (c. 1900 BCE) completely destroyed the flagging township in a single stroke. Archaeological analysis shows that the basin and dock were sealed with silt and debris, and the buildings razed to the ground. The flood affected the entire region of Saurashtra, Sindh and south Gujarat, and affected the upper reaches of the Indus and Sutlej, where scores of villages and townships were washed away. The population fled to inner regions.
