ABSTRACT
Aerial photocomposites and field research reveal numerous post-Pleistocene fluvial remnants associated with former courses of the Indus river in the lower Indus basin of Sindh province, Pakistan. Geomorphologic and historical data were used to connect fluvial remnants and to delineate former courses of the Indus river from northern Sindh to the Arabian Sea. Sindhu Nadi was a prior course of the Indus river during 4000-3000 BC. Also at this time a second exclusive perennial river, Nara Nadi, existed in the east part of the lower Indus basin. Sindu and Nara Nadi were confluent in the southeastern lower Indus basin, with the prehistoric coastline occurring north of the present location. Ancient river course locations affected prehistoric Indus civilization ( ~2600-2000 BC) through flood hazards and access to water for irrigation.
