While landforms in a drainage basin have been the basic ingredient for land use, floods in some basins are seen to act partly as boons in the midst of their many faceted problems as well as the anthropogenic actions and results. The river is an active agent on landforms that controlled the entire study area. The geo-fluvial characteristic of a river basin has been dominated by the morphology and the hydrological regimes of the river. The middle Brahmaputra River basin in the hub of the North East India below the high standing Bhutan Himalaya has since the last 4-5 decades been observed to create the flood menace to not only standing crops, human habitation but also to other kinds of land uses in the area under the river’s domain. The middle part of the basin has its peculiar landform characteristics that can be well counted through surficial relief, slope, dissection, drainage net, vegetational cover along with soil types and their capabilities yielding characteristic combination of land uses. Over the analyzed period the geo- fluvial parameters are frequently changed under the spatio-temporal domain. Hydro-morphological aspects are influenced by the river basin parameters including channel shifting rate, braiding index, sinuosity index, etc. The middle part of the basin being flooded frequently due to high storm rainfall in its catchment uses to cause the high damage to land including river planform, people and environment. The terrain characteristics of the region influenced the hydraulic parameters and their impact on the landform. The Brahmaputra River frequently changed the thalweg causing drastic change on sand bar location. In the dynamically substitute landforms that are formed island and sandbars, it is beneficial for the riparian vegetation and agricultural land. Therefore, there has been an outmost need to evolve the area specific strategies for mitigation of fluvio-geomorphologically associated problems in order to protect and progress land use pattern on the one hand and the human society on the other.
