Abstract [en]

Every year a number of breach failures occur in Irrigation Canals in Sindh. Those failures cause displacement of thou-sands of people, destruction of properties, land, and damages costly crops worth millions rupees. In addition to that breach failures are also can cause water shortages when failure occurs during peak demand period. There are various causes of embankment failures that include overtopping, internal erosion, structural defects and piping. State of art for breach failures is presented in this paper and suggestions for prediction of breaches in context to canals in Sindh are discussed. Seepage and slope stability analyses are recommended for long term breach predictions.
