Umesh C. Kothyari, Auteur ; Kenjirou Hayashi, Auteur ; Haruyuki Hashimoto, Auteur |Results of an experimental study on the drag force measurement involving a single stem kept in a channel flow stem array are presented. The data collected herein and those from literature indicate that the stem drag coefficient logarithmically i[...]

Bhaskar Ramesh, Auteur ; Umesh C. Kothyari, Auteur ; Krishnan Murugesan, Auteur |The motion of sediment particles over a transitionally-rough bed is studied experimentally using a real-time high-speed imaging system. Vertical distributions of the instantaneous flow velocities were measured using acoustic Doppler velocimetry.[...]

Sarbjit Singh, Auteur ; Zulfequar Ahmad, Auteur ; Umesh C. Kothyari, Auteur |A numerical scheme based on the split-operator approach was developed for the solution of two-dimensional mixing equation with a transverse line-slug source in open channels. An exact solution of the advection equation was developed by adopting [...]
