Dykes - Settlement allowance
Unit 4- Layout planning of fish ponds
Settlement allowance
A newly constructed dyke keeps on settling for some time due to its huge height and compactness. The amount of settlement will depend on soil material used for construction, soil moisture content during construction, amount of compaction done during construction and speed of construction. The usual allowance for settlement allowance is approximately 10% of the height of the dyke. The rate of settlement of various soils is given below
- Ordinary earth - 1½ – 2” per foot of height
- Compact earth - 1” to 1½ “ per foot of height
- Black cotton soil - 2” to 3” per foot of height
