Describe the primary features and benefits of a rockfill dam.
When constructing a rockfill dam, loose rock or gravel is frequently stacked and coated with an impermeable facing or core to prevent water seepage. One of the key characteristics is a flexible and adaptive structure that can tolerate shifting foundation conditions and seismic activity. Rockfill dams are useful because of their easy construction and abundant supply of materials. They are typically used in wide valleys where the foundation of other types of dams might not be ideal. The main advantages are their ability to control settlement and cost-effectiveness. However, they must carefully regulate the water flow to ensure the integrity of the rockfill and core.
