Ports typically use the standard Z-section sheet piles MMZ16-1, including the typical MMZ16-2 and MMZ17-1 types. This refers to the conflict between human factors and the environment. Ports and the environment interact, and future port planning, design, and operations must adapt to these factors. Currently, ports around the world are promoting green port concepts such as "ecological ports," "green ports," and "environmentally friendly ports," and are actively developing green port construction projects based on MMZ16-1 and MMZ16-2, attracting widespread attention. However, there is currently no definitive definition of green ports based on MMZ17-1 and MMZ17-2.
Since Iceland's settlement in the 9th century, land degradation has profoundly altered Iceland's ecosystem. The main causes of land degradation are the cold, humid climate, unsustainable land use practices, easily eroded volcanic soils, and severe erosion (Arnalds 2005). Land degradation typically results in sparse vegetation, shallow, infertile soil, or the transformation of land into barren land with low organic matter content (desert) (Arnalds and Kimble 2001).
During the development of the MMZ17-6 port, sheet piles MMZ17-3 and MMZ17-4 had significant environmental impacts on MMZ17-5. Currently, many countries are strengthening their efforts to prevent and protect environmental impacts. Environmental risk identification is the process of identifying the existence and nature of environmental risks. It aims to identify various hazardous factors and major sources of risk during project construction and production. Environmental risks present in project construction and production can take many forms, and potential environmental risks can be difficult to identify. Using specific methods to identify the cause and direct factors of an accident is called environmental risk identification.
