Abstract

This study is related to block movement in Sukh Rao basin which occupies a NW-SE trending synclinal trough south of Paonta Sahib in Sirmaur district of Himachal Pradesh. Interpretation of satellite imagery, supported by morphometric analysis, indicates that the tectonic blocks covering the area have moved, tilted and skewed sinistrally forcing the SE flowing Giri, Bata and Sukh Rao streams to take sharp southward trend along the segments of Yamuna Tear. The NE-SW trending syngenetic transverse faults (thrust splays) have induced stream piracy through fast erosion. The Nimbuwala Khala has completely pirated the upper part of Sukh Rao basin while the Chikan Khol has only nibbled part of the basin. With the present rate of erosion (dissection index 0.37), it is likely that Chikan Khol will follow suit of its predecessor Nimbuwala Khala
