Title

TECTONIC INTERPRETATION OF DIGITAL TERRAIN DATA THROUGH MORPHOMETRIC ANALYSIS OF THE REGION AROUND LANJA, DISTRICT RATNAGIRI, INDIA.

Authors

Abstract

The presence of geomorphic features such as regional anisotropy, tilted terrain, linear valleys, ridgelines slope breaks and steep slopes of uniform aspect reflects tectonic movement in the region. Numerical analysis of Digital Elevation Models (DEM) helps characterise tectonics in the area quantitatively. This study investigates numerical geomorphometric methods for tectonic geomorphology of the southern region of Deccan Traps in the Konkan Coastal Belt (KCB). The essential geometric attributes (elevation, slope, aspect and curvatures) complemented the automatic extraction of ridge and valley lines and surface-specific points. Evans’ univariate and bivariate methodology of general geomorphometry extended with texture (spatial) analysis methods, such as trend and autocorrelation analysis. Terrain modelling implemented with the integrated use of (1) numerical differential geometry; (2) digital drainage network analysis; (3) digital image processing; and (4) statistical and geostatistical analysis. the Lanja area is tectonically controlled, wherein N-S tectonic lineaments are more active than NW-SE, ENE-WSW and NE-SW lineaments. The present landscape is the result of the interplay between tectonic activity and fluvial response to it.
