摘      要：The present study area,Dadra and Nagar Haveli,contains several lineaments and traces of active *** various aspect of the geomo rphic analysis,i.e.,stream length(SL) gradient,hypsometric integral(HI),basin shape(BS),valley floor(VF),have been applied to evaluate the relative index of active tectonics(RIAT) of the Damanganga *** high and low zones of tectonic activity have been identified based on the geomorphic analysis of the *** evaluation of all indices,three classes,class IIhigh(1.3 ≤RIAT 1.5),class Ⅲ-moderate(1.5 ≤RIAT 1.8),and class Ⅳ-low(1.8 ≤RIAT),have been obtained to outline the degree/gradation of comparative tectonic activities in the study *** appraised outcome of the RIAT dispersal is also well reinforced by the geomorphic evidence in the *** collective outcomes of geomorphic evidence,such as stream deflection and analysis of lineament,deflection of streams,and geomorphic indices,conceal that the Damanganga watershed is affected by tectonic activity.
