MODELLING OF DEPOSITION AND EROSION PROCESSES ALONG A 180° OPEN CANAL BEND BY NAYS2DH IN iRIC
This paper presents experiments and computer simulation for the erosion and deposition processes along a 180° open canal bend. The computer simulation is conducted by Nays2DH model in iRIC software. The models are conducted with the curvature's radius ratio (Ø/L) varies within 3.0 to 8.5. Experiments produced that the erosion and deposition actions decrease as Ø/L increases. The minimal erosion and deposition are detected at (Ø/L =8.5). The optimum place of a bridge circular support along the bend is defined. The results of Nays2DH Model are compared with tests. RSQ for the modelled statuses is 88.329% and the correlation factor between simulations and the gauged depths is 93.98%.
