摘要

Sri Lankas hydraulic heritage goes back to sixth century BC, where many dam engineering achievements were made to restore water for agricultural development. Water resources development through the use of storage in storage Dam/Reservoir has been the element of rural integrated development strategy in Sri Lanka. Selected 32 Dam/Reservoirs for the risk assessment study varies from ancient earth dams renovated for varying degrees, concrete gravity dams constructed middle part of the last century and modern rock fill and double curvature arch dams constructed during latter part of the last century. Risk assessment study shows that while the modern dams have been generally built to current standards of the world best use practices same cannot be said for all other dams. Many dams are showing the signs of aging (such as seepage, leakage, cracking and scouring) and other have significant monitoring, safety design, maintenance, reservoir conservation and other safety tissues.
