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.
