What is the term for the process of covering a landfill with soil and planting grass to improve aesthetics and prevent erosion?

The process of covering a landfill with soil and planting grass to improve aesthetics and prevent erosion is referred to as capping. Capping serves multiple purposes: it helps to stabilize the landfill, reduces odors, and prevents the migration of waste materials. By covering the landfill with a soil layer, it also facilitates vegetation growth, which further contributes to erosion control and enhances the visual appeal of the area.

In contrast, land reclamation refers to the broader concept of restoring land that has been disturbed or contaminated due to industrial use or natural events, making it suitable for future use. Site remediation specifically addresses the cleanup of contaminated sites to remove pollutants and restore the land to a safe condition, often involving complex processes beyond just covering with soil. Soil enhancement, while related to improving soil quality, does not specifically address the process of covering landfills for stability and aesthetic purposes. Thus, capping is the precise term that matches the offered description.
