What should be done with earth dikes to maintain their effectiveness?

Maintaining the effectiveness of earth dikes is crucial for controlling erosion and sediment movement. Compaction plays a significant role in this process. When earth dikes are compacted, they are less likely to lose their structure due to water flow or rainfall. Proper compaction ensures that the dikes can withstand the physical pressures exerted on them, preventing washouts and maintaining their ability to redirect or contain water.

Furthermore, compacted dikes have reduced porosity, which helps minimize water infiltration that could lead to instability. Regular checks and maintenance of compaction levels according to established guidelines or standards are essential to ensure the dikes serve their purpose effectively over time.
