NWFP is a rich province in water resources and therefore irrigation canals have water allowances higher than any other province in Pakistan. If these canals are operated according to existing supply based operation then it would lead to water logging of fertile land and would cause severe water losses as well. To avoid this situation, there is a need to devise such canal operation plans which can prevent these adverse effects of increased irrigation supplies. In this situation, the water should not be let unjustifiably to the irrigators, otherwise they would over-irrigate their lands and will cause waterlogging. This can be tackled by adopting a semi-demand based canal operations approach which has two-tiered benefits of water saving and preventing waterlogging. Crop Based Irrigation Operations (CBIO) is a canal operations strategy which can achieve these objectives, if implemented in true sense. In this paper the development, implementation and benefits of CBIO have been discussed, while implementing it on Machai-Maira irrigation canals.

The Upper Swat Canal Pehur High Level Canal irrigation system in North Western Province,Pakistan is a combination of upstream and downstream control branch canals, Machai, PHLC andMaira. It draws water from both Swat River and Indus River. Upstream control system consists ofeleven manually operated vertical gates and the downstream control system is fully automated andconsists of thirteen AVIS / AVIO cross regulatory gates and PID control and SCADA system.The irrigation practice in the project area is a combination of Full Supply System and Warabandi.Crop Based Irrigation Operation (CBIO) is applied for optimizing the usage of water and alsominimizing the water logging problem in that area.This water demand and related supply varies during the growing seasons and as such it is timedependant, it requires an unsteady or quasi steady modelling approach. This study is mainlyaimed to calibrate the canal flows and levels and to check the performance of the automateddownstream control system with respect to meeting the CBIO based target supply.The mathematical model for Simulation of Irrigation Canals (SIC) is used to simulate thehydraulic behaviour of the canal system under steady and unsteady flow conditions. Simulationresults reveal that all three branches, Machai, Maira and PHLC of this system posse their desiredcapacities under design conditions. However, the calibrated Maira Branch cannot pass the designdischarge as the regulatory gates are partly closed due to the higher water levels caused by higherroughness value of the canal than the design.The unsteady simulations for the total system become unstable with the present version 4.22 ofSIC model because of super critical flow conditions. Only the Maira Branch is simulated underunsteady flow conditions for only flows less than the existing capacity of the canal.
