摘      要：The study of drainage patterns in tectonically active regions is conducive to the prediction of regional *** subsurface changes can be detected by drainage conditions and manifested in the form of drainage *** Satluj valley of Bilaspur,which is traversed by numerous faults in northwest Himalayan region,was selected to analyze the effect of active tectonics on drainage *** the Persistent Scatterer Interferometric Synthetic Aperture Radar(PS-InSAR)technique,SENTINEL-1A data were used to estimate the active surface deformation between September 2015 and December *** results show that the region between Barasar Thrust(BrT)and Main Central Thrust(MCT)is undergoing deformation of±12 mm/*** Stream Power Incision Model(SPIM)was used to predict deformation *** validate the tectonic activity generated by the drainage network,seismic bvalues were calculated,indicating the accumulating *** study shows the importance of drainage anomalies in tectonically active *** used in close combination with other seismotectonic parameters,drainage anomalies can be effective in delineating tectonically active regions.
