River morphology describes a river's cross-sectional shape, sedimentation, and erosion. The meandering parameters, oxbow formation and decadal Land usage Land Cover fluctuations of Barak River were investigated using 21 meandering spans to measure river morphological changes. The decadal meandering parameters were calculated reach-wise and section-wise to characterize river morphological changes. It was observed from the paired t-test that the river width significantly changed during the study period (1990–2020). Strong inter-relationships between the meandering parameters are shown from the regression analysis. The morphological investigation found a reduction in the centerline distance due to variations in the radius of curvature caused by the internal arc's reduction. As a result, the average sinuosity has decreased over time. The current work used SVM and ML techniques for LULC classification, and a comparison of ML and SVM techniques was also done. The SVM technique performs better. The decadal LULC analysis suggests that between 1990 and 2020, the areas of water bodies, forests, and bare land types declined. Whereas, agricultural and settlement areas increased. River morphology is substantially impacted by agriculture and urbanization, particularly in areas where oxbows occur simultaneously, since this work may apply to other similar meandering river management along the alluvial flood plain.

The study examined the spatial analysis of the morphometric characteristics of the Lower Orashi River, Niger Delta Region, Nigeria. The river course was segmented into 30 equal distances of 4.8m from each other and at each point, the morphometric parameters like width, depth, and flow velocity. The discharge was measured from these parameters. Descriptive and inferential statistics were employed for data analysis while results are presented using tables and graphs. Results showed that width of the river ranged from 77.90m to 2788.00m with the mean width of 318.83m. The depth ranged from 2.10 to 7.60m with the mean depth recording 4.14m as it was higher at the upper section of the river while it becomes lower as it is entering the Atlantic Ocean. Furthermore, width was significantly correlated with the depth (r= -0.556, p<0.05), cross sectional area (r= 0.989, p<0.05) and discharge (r= 0.987, p<0.05). Also, elevation was significantly correlated with cross sectional area (r= -0.506, p<0.05) and discharge (r = -0.511, p<0.05). More importantly, the cross sectional area was correlated with discharge (r=0.995, p<0.05). The study concluded that there is significant variation existing in the morphometric parameters namely width, elevation, cross sectional area and discharge among the segments along Orashi River. The study therefore recommended that the water course should be reduced of human activities to reduce the rate of soil loss or discharge and to boost the river floor with adequate morphological property.
