Appreciating the explanation given by Ahmad Nourbakhsh, it will be good to say that there is a fine line of demarcation. In 'Tectonic Geomorphology', we are essentially interested in understanding the existing geomorphic features as well as changing landforms in the light of tectonic forcings. On the other hand if from seismological data or some other geophysical evidences, we are having a structural model of a particular study area and some of the geomorphic features are used to validate(or question) those models, it will be treated under 'morphotectonics'.

I would like to request Meelad to go through two of our recent publications on these issues.

I`m appreciated your answers Ahmad Nourbakhsh and Siddhartha Kumar Lahiri.... I see the textbooks for the (Ollier, C.D., 1985) and ( Burbank and Anderson, 2001) and (Adrian Scheidegger, 2004)... was titled their books withe tow terms... So it seems the morphotectonics have global scale like continents and local scale like river drainage basin, lake basin shore or coast line than the tectonic geomorphology that certainly stressed on the relation between the tectonics and geomorphology.....

I`ll traced the terms in all publications (Books, Journals, Theses) 

Mr. Siddhartha Kumar Lahiri. I couldln`t  download your paper http://dx.doi.org/10.1016/j.geomorph.2014.04.032

and I`m happy to read the discussion about the 2nd link.... this add to me more comprehension about the subject.....

Thank you Meelad for going through the links. If your institute has access facility for the Journal 'Geomorphology' (Elsevier) you will find the link in 'Articles in Press' category. The online version is available since May, 2014. The Hard version is supposed to come in the 'Tropical Rivers' Special issue of the Journal.

Best wishes,
