ABSTRACT: Every
year, a number of breach failures occur in Irrigation Canals in Sindh. Those
failures cause displacement of thousands of people, destruction of properties,
land, and damage to costly crops that worth millions Rupees. In addition to
that, breach failures also can cause water shortages when the failure occurs
during the peak demand period. There are various causes of embankment failures which
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 a long-term breach predictions.
