“…At a societal level, identification of these abandoned river channels is important as they may help in identifying freshwater pockets within the densely populated areas of the city in the coastal region; in addition, they may also show potential natural pathways for channeling of the drainage system. From a geological perspective, this study, in conjunction with that of Jana et al 3 , highlights that a number of palaeo-channels exist in the delta region unlike in the upstream region of the River Mahanadi.…”

“…Aligned depressions along a channel trace may thus help to identify a remnant river valley, which can be detected in spatial profile, i.e. plot of elevation against distance 3,23 across the suspected channel. In the present study, spatial profiles have been drawn across the three transects T1-T3 (suspected to be palaeo-channels) on SRTM data with spatial resolution of 30 m (Figure 6 b).…”

“…In this study, we report the existence of a palaeo-channel that apparently bisected Puri town, and argue that it may correspond to the 'lost' Saradha river described in ancient literature. Recently, Jana et al 3 identified the palaeo-channel of another river of possible historical significance, the Chandrabhaga, in proximity of Sun Temple at Konark. At a societal level, identification of these abandoned river channels is important as they may help in identifying freshwater pockets within the densely populated areas of the city in the coastal region; in addition, they may also show potential natural pathways for channeling of the drainage system.…”

Palaeo-Channel Bisecting Puri Town, Odisha:Vestige of the Lost River ‘Saradha’?

et al. 2018

Puri, an ancient town located on the Odisha (Orissa) coast in eastern India, is associated with the 12th century CE Jagannath Temple. Many ancient and historical texts mention a mythical river named Saradha that flowed across the present Grand Road (Badadanda) between the Jagannath and Gundicha temples in Puri, dividing the town into two parts. This study traces the trail of a palaeo-channel beyond and within the heart of Puri town through an integrated study of geology, satellite imagery and ground-penetrating radar (GPR) survey. Various satellite imagery manipulation techniques -band combination, NDVI, MNDWI, linear spectral unmixing algorithm, density slice and spatial profiling -indicate the existence of water components along with vegetation bands, and the presence of a sinusoidal palaeo-channel trace with a V-shaped topographic outline. This is interpreted to represent the remnants of an extinct river valley. GPR survey also suggests that a subsurface river valley, about 128 m wide, existed across parts of the Grand Road. A large, sinusoidal water body near the sea beach at Puri, may represent the last remains of the dried-up channel. Integration of all these features suggests that a river once existed between Jagannath and Gundicha temples in Puri town. The constructed palaeo-channel trail may be that of the lost Saradha river described in ancient texts. The study develops a sequential methodology for identifying palaeo-channels even in urbanized localities like Puri.
