Dykes - Wave allowance
Unit 4- Layout planning of fish ponds
Dykes
Wave allowance / height
Dam height must be sufficient to prevent over topping due to wave action. Wave height is a function of fetch. Which is un obstructed straight inedistance from the furthest point of the pond to the dyke. It is straight line distance from the dyke to the closest point on the obstruction. Wave may cause erosion of the dam face if precautions are not incorporated into the design.
Wave height can be calculated with relation to the fetch by the following equation.
