What strategies could be implemented into Mokpo as adaptation measures in their planning policies?
The types of adaptations
Sea Wall Construction-Hard ProtectionThere are a variety of construction methods that can be used to create sea wall protection for a coastal city.Site analysis and the longer term objective of the sea wall would determine the type of finished product to be achieved. Also the ocean currents and onshore winds would also contribute to the amount of anticipated water inundation an area could potential receive.
Sea wall construction is often combined with back filling from materials dredged from the ocean or material imported to the site. These areas can then be used for soft protection of the coast line incorporating coastal vegetation that will stabilize the soil and prevent ersoion |
Soft Protection- Vegetation and Wetlands
Reclaimed coastal land is used as a buffer zoned for the inundation of water from rising seas.This land often acts as drainage systems for the excess water allowing the disbursement of the excess water over an extended period of time.The area can also be utilized as recreational areas for the city, providing nature walks.parks and playing fields. The wetland areas protect the wildlife of the locality providing a safe eco friendly environment for their sustainable future. The green spaces also help the city to mitigate their carbon footprint,helping to balance their carbon emissions and contributes towards their green sustainability ratings.
Adaptation Protections suitable for Mokpo city
The adaptation plan was designed to cater for each of the 3 subject area's inundation potential with the aim of protecting existing infrastructure in the short term and develop a plan to mitigate the impact of the rise in sea level thru adaptive planning guidelines.
Area A:
The recommendation is for the construction of hard protection such as the construction of substantial terraced sea walls to protect the lower areas located between the 2 coastal hills .This will prevent erosion and the destruction of the reclaimed areas. The dredged sands can be contained behind the walls and can be incorporated into the preparation of recreation area and road networks in the short term That can be act as drainage pitts in times of high tide.
|
Area B:The recommendations for Area B, in the shorter term, is for offshore dredging to build up the foreshores of the district.This would create a deeper buffer zone of soft protection to the existing commercial hub,which once again,is to be utilised as dual purpose green space for recreation and drainage .
In the Longer term, projections plan for the retreat of coastal commercial developments to higher ground being the optimum choice as the soft protection will only slow down the impact of the inevitable. |
Area C:
Area C is expected to suffer the greatest detriment to the rising water so it is was recommended that the planning process undertake a phased implementation plan
.Phase 1 would involve accommodation protection, creating new inland residential communities in lower risk areas Phase 2 would retreat the marine transport hub upstream and this would be surrounded by soft protection in the form of green space and wetlandparks. Phase 3 would see the building of hard protection in the form of sea walls around the foreshore of exisiting residential area The fill cut from the new port area would be utilised to increase the areas elevation behind the wall and for the subsequently redevelopment of this area into new high rise residential areas ,a commercial hub and a railway network linking back to the inland communities. |
