![]() These are the most obvious defensive methods. They’re no where near as effective as hard engineering techniques but they’re far more sustainable. Soft engineering techniques are low tech, low cost solutions that work with nature to reduce erosion. They do little to work with nature and sustainability is a key issue with them, despite their initial signs of success. As usual, hard engineering techniques are high technology, high cost, human made solutions. Like most engineering schemes in geography, there’s hard and soft coastal engineering. ![]() This is generally what happens in areas where there’s no people, and so nothing of “value” (to the government) to protect. Do nothing - The easy option, deal with the effects of flooding and erosion as they come or just ignore them.Retreat the line (surrender) - Move people out of danger zones and let mother nature unleash take control.Advance the line - New defences are built further out in the sea in an attempt to reduce the stress on current defences and possibly extend the coastline slightly.Hold the line - Where existing coastal defences are maintained but no new defences are set up.When engaging in coastal management, there’s four key approaches that can betaken: Management of coastlines is also important to help protect natural habitats, however governments generally don’t engage in coastal management where there isn’t an economic risk as effective coastal management is very expensive. ![]() Failure to do so can have severe economic and social effects, especially along coastlines which are used for tourism and industry (pretty much all of them). The reason for coastal management is obvious, to protect homes and businesses from being damaged and even destroyed by coastal erosion or flooding. It’s becoming increasingly important for councils and governments to start managing coastlines in order to protect them from increasing coastal erosion and flooding due to altering sea levels. You should really enable it for this site but most things should work without it.
