ABSTRACT
A landform is defined by the Landscape Institute (1995) 1 as a ‘combination of slope and elevation producing the shape and form of the land surface’. Natural landforms are the result of geological processes. The processes occur over millions of years in the formation of sedimentary rocks, as a series of cataclysmic orogenic events, or as a continuing response to climatic and hydraulic forces. However, physical processes can be modulated or accelerated by man’s interference, such as through agriculture or construction. For thousands of years, man has moved rocks and earth to create fortifications, flood protection banks, canals, dams, roads and harbours, or to win ores, fossil fuels and building materials.
