The study of the hydrological characteristics of a river is an important aspect in order to study the spatial variations and flow dynamicity of the river. The geomorphic signatures of the river can be indirectly assessed with the help of its hydrological character at a specific river stretch. The Subarnarekha river eastern India, traverses over varied geomorphology and this variation can be related to the hydrological signals, it leaves behind, at different reaches. A detailed statistical analysis throws light on the flooding character of the river which was done through flow histograms, yearly variations of water levels, river regime, recession curve analysis and rating curves. The study reports two specific findings. Firstly, the flow regimes are experiencing a change and there is a decline in the quantity of water flowing in the river in the present compared to the past. Secondly, there is a spatial variation in the flow patterns that are experienced by the different hydrological stations located in the different reaches of the river. The plateau region stations are experiencing high magnitude low frequency floods whereas the alluvial floodplains are experiencing low magnitude high frequency events. [ABSTRACT FROM AUTHOR] |
