The Orchha River: Physically based modeling of bedrock incision by abrasion, plucking and macro abrasion “Every man has his secret sorrows which the world knows not; and often times We call a man cold when he is only sad.” ― Henry Wadsworth Longfellow Rajkumar Dongre The Orchha River in rainy days -Channel incision into bedrock plays an important role in orogenesis by setting the lower boundaries of hillslopes. The longitudinal profiles of bedrock channels constitute a primary component of the relief structure of mountainous drainage basins and thus channel incision limits the elevation of peaks and ridges _____________________________________________________________________________________ Abstract [1] Many important insights into the dynamic coupling among climate, erosion, and tectonics in mountain areas have derived from several Keyword: Macroabrasion, numerical models of the past few decades which include descriptions of bedrock incision. However, many questions regarding incision processes Orchha, Knick dominate, and morphology of bedrock streams still remain unanswered. A more bed rock River, Chunks. mechanistically based incision model is needed as a component to study landscape evolution. Major bedrock incision processes include (among other mechanisms) abrasion by bed load, plucking, and macro abrasion (a process of fracturing of the bedrock into pluckable sizes mediated by particle impacts). _________________________________________________________________________________ Mobile: 09301953221, Email:
