EFFICIENCY AND HYDRAULIC PERFORMANCE OF CANALS EXPOSED TO UNCONTROLLED MAINTENANCE PROGRAMS AND DREDGING

Abstract
Key Words:
Canal Performance; Water Distribution Efficiency; Dredging; Channel Maintenance.
Summary:
As a result of implementation of uncontrolled maintenance programs and oppressive dredging to irrigation canals, these cross sections became deeper and wider. The main objective of the study is to identify the effects of regular and irregular changes in canal cross sections which may be occurred during improper maintenance. The research included the study of increasing canal width, lowering canal bed and increasing side slopes. El-gharaq canal was selected as a case study to illustrate the effect of irregular changes in cross sections in hydraulic characteristics. All scenarios were developed numerically using SOBEK 1D. For all scenarios water levels, velocities, section factor, conveyance efficiency and water distribution efficiency were compared with the corresponding designed values.
