Endorsing fully the answer provided by Mohammad Firoz Khan, it will be good to add that adding temporal variability in morphometric analysis of different geomorphic features like river dynamics and evolution of river islands, 'tectonic forcings' can also be identified which play very significant role in framing holistic kind of 'Integrated Basin Management Policy'. Otherwise, most of the policy measures are run strictly from the 'Civil Engineering' perspective where dynamic agencies like rivers are treated as intruders into the 'Development Paradigm'. Thus, a patient measurement of morphometric parameters help to understand 'what' exactly is happening and subsequently by adding inter-disciplinary approach 'why' part of the problem can also be explored. Particularly, in tectonically controlled active basins, before going to raise mega structures like 'Big Dams' these studies are very essential.

Recently, we did studies in this direction in the upper part of the Brahmaputra valley. The reference is given below:

Morphometric analysis, quantitative description and analysis of landforms as practiced in geomorphology that may be applied to a particular kind of landform or to drainage basins, many quantitative measures have been developed to describe valley side and channel slopes, relief, area, drainage network type and extent, and other variables. Attempts to correlate statistically parameters defining drainage basin characteristics and basin hydrology have yield significant results. The morphometric analysis of the drainage basin and channel network play an important role in understanding the geo-hydrological behaviour of drainage basin and expresses the prevailing climate, geology, geomorphology, structural antecedents of the catchment. Morphometric analysis of a drainage basin expresses fully the state of dynamic balance that has been attained due to dealings between matter and energy. It finds out geomorphologic and structural control of flow and runoff and is helpful in predicting floods, their extent and intensity. The study reveals that morphometric analysis based either in GIS environment or otherwise is a competent tool for geo-hydrological studies. These studies are very useful for identifying and planning the groundwater potential zones and watershed management, including the whole gamut of natural resources connected with the watershed.

Thanks sir

thank you so much  I am working this for flood Plain Management 

How then could morphometric analysis be done on deep water channels assuming 3D seismic is the only available data?
