Abstract:

Irrigation systems have hydraulic structures to regulate and distribute the flow. These structures play the important role in the overall management of the system. In this paper the hydro dynamic model CanalMan, which is based on the solution of one-dimensional Saint Venant equations of continuity and momentum was applied to investigate performance of such structures. Dagai Distributary, which is a secondary canal in the Maira Branch of Upper Swat Canal Irrigation System. North West Frontier Province of Pakistan was selected for investigation. The year of study was 2005-06. The aim of the study was to apply a hydrodynamic model to a canal and to assess the performance of canal outlets under different discharge conditions. Four cases of 100%, 80%, 70% and 50% of design discharge were tested. Canalman model was successfully calibrated for Dagai Distributary. It was found that majority of the canal outlets were not drawing discharges according to their allocations for all the four discharge levels. The operation of canal between 100-70% of full supply discharge has been recommended.
