Stochastic Suspended Sediment Dynamics in Semi-Bounded Open Channel Flows: A Reflected SDE Approach
Manotosh Kumbhakar, Christina W. Tsai
Stochastic processes, in the form of stochastic differential equations (SDEs), integrate stochastic elements to account for the inherent randomness in sediment particle trajectorie…
Full-Range Approximation for the Theis Well Function Using Ramanujan's Series and Bounds for the Exponential Integral
Manotosh Kumbhakar, Vijay P. Singh
The solution of the governing equation representing the drawdown in a horizontal confined aquifer, where groundwater flow is unsteady, is provided in terms of the exponential integ…
Vertical sediment concentration distribution revisited with shear-induced diffusivity: An explicit series solution based on homotopy analysis method
Punit Jain, Manotosh Kumbhakar, Koeli Ghoshal
The present study revisits the vertical distribution of suspended sediment concentration in an open channel flow with a special attention to sediment diffusion coefficient. If turb…
Mathematical Modelling of Streamwise Velocity Profile in Open Channels Using Tsallis Entropy
Manotosh Kumbhakar, Rajendra K. Ray, Suvra Kanti Chakraborty +2
This study derived the vertical distribution of streamwise velocity in wide open channels by maximizing Tsallis entropy, in accordance with the maximum entropy principle, subject t…
On the Role of Tsallis Entropy Index for Velocity Modelling in Open Channels
Manotosh Kumbhakar, Rajendra K. Ray, Koeli Ghoshal +1
Following the work on Shannon entropy together with the principle of maximum entropy, Luo & Singh (J. Hydrol. Eng., 2011, 16(4): 303-315) and Singh & Luo (J. Hydrol. Eng., 2011, 16…
