Abstract Humans constitute one of the main geomorphological agents in modern times. As an example, post‐mining regions represent a typical landscape Anthropocene. Strong relief modifications are particularly obvious with open pit mining. However, many existing mining areas lacking detailed pre‐mining information for quantification anthropogenic changes, which is considerable challenge historic ...
