Design of pondsTop Width
The top width or crown of the dyke depends on the height of the dyke and its purpose. Engineering standard require a minimum top width of 2.4 m for all dykes between 3 to 4.5 m high. Dykes between 4.5 to 6m require a top width of 3.7 m. However in actual practice most of the main dykes of a coastal aquaculture farms are built with a top width between 1.5 to 2.5 m. If the dykes are to be used as a roadway a minimum of 3.7 m top width should be provided.
