MUKHERJEE, Sucheta y JHA, V.C.. Morphotectonics and resultant features in Kaliani River Basin (Assam). Soc. nat. (Online) [online]. 2011, vol.23, n.2, pp.285-294. ISSN 1982-4513. http://dx.doi.org/10.1590/S1982-45132011000200011.
The surficial structure and impressions upon the crust due to endogenetic and exogenetic mechanisms are witnessed all around us. These landforms have evolved as a result of plate movements, subsidence, upliftment and various erosional processes. This concept can be collectively referred to as morphotectonics of any region and can be used as a key to understand its genesis as well as present physical state. Morphotectonics refers to forms and shapes that have evolved in the past or in recent times as a result of past or recent tectonic activity. The most vivid evidences of past tectonic activity can be assessed through drainage lines, in any area which are guided and controlled by physical structures over which they flow.
