Abstract
The paper develops and implements remodeling approach for alluvial irrigation channels. The approach mainly includes in-depth analysis of original/existing design parameters, identification of existing condition of channel and hydraulic structures along with their problems.Evaluating different options and finalizing the remodeling parameters by emphasizing hydraulic, structural and economic consideration. Upper Jhelum canal in Pakistan was selected as case study channel. The condition survey of channel was conducted which showed that it was facing multiple problems i.e. excessive silt deposition, erosion of banks, inadequate freeboard, side embayment and widened channel section. The channel was unable to run at the design discharge and therefore required remodelling. The reasons for multiple problems were diagnosed during the study. The analysis showed that the viable approach for remodeling of subject canal is at enhanced design parameters. Different options were developed by varying different hydraulic parameters and possible economical solutions were analyzed using different approaches to suggest the most suitable remodelling strategy for UJC. The existing parameters with minimum change became basis for re-designing of the channel by different approaches i.e. Lacey's regime theory, Manning's formula and Tractive force method. Sensitivity analysis was also carried out to finalize the design parameters emphasizing hydraulic, structural and economical consideration. The remodelling of UJC as per recommended parameters will ensure increased agriculture and power benefits and enhance conveyance efficiency.
