Rising sea levels and storm surge damage

Rising sea levels and risk of storm surge damage along coasts

A 0.82 m rise in sea level by 2100!?

The IPCC 5th Assessment Report envisions a variety of scenarios and predicts the impacts of climate change. Of these, the worst-case scenario predicts sea surface levels to rise by a maximum 0.82 meters. Causes included melting of ice sheets at the South Pole and Greenland, glaciers in the Alps, and permafrost.
Among the impacts of rising sea levels, first is a reduction of land. In the case of Japan, according to predictions made by the National Institute for Environmental Studies, in the worst case at the end of the year 2100, 83 to 85% (approximately 172 km²) of sand dunes will have disappeared, as will have 12% of tidelands. In this case, impacts will also be wielded on ecosystems that require sand dunes and tidelands. The IPCC report also points out that storm surges, coastal flooding and rising sea levels caused by climate change will wield impacts and damage to health in low-lying coastal areas and small island nations, and calls for countermeasures.

What ICT can do for rising sea levels and storm surge damage

ICT plays a critical role in predicting the degree of sea level rise and its impacts. Not only for global predictions such as estimations made for IPCC, ICT is also indispensable in making more concrete and detailed predictions at the national and local government level.
If we can discern what lands will be able to avoid the tremendous damage of rising sea levels and storm surges in the future based on simulations using ICT, we can enact measures to avoid impacts, or to prevent and mitigate them, such as relocation to higher ground and construction of breakwaters. Further, predicting the occurrence of disasters through ascertainment of changing tide levels in real time using various kinds of sensors, in combination with weather information, enables us to evacuate and take countermeasures in advance.

What NEC can contribute to addressing rising sea levels and storm surge damage

Tide level monitoring

In order to prevent and control damage due to rising sea levels, tide level observation over the long term and forecasting of the short-term impacts that accompany climate change are required. Through continuous monitoring of tide levels utilizing sensors, NEC supports the monitoring of storm surges as well as tsunamis and rising sea levels brought on by global warming.

  • Advance measures such as installation of storm surge barriers
  • Prompt responses and evacuation prior to storm surge damage

Floodgate monitoring and control

The increased occurrence of larger and stronger typhoons will reputedly be brought on by climate change. In regions where storm surge damage is predicted, the prompt and secure operation of floodgate facilities is called for. At NEC we contribute to the safety and security of communities through remote monitoring and control of flood-gates utilizing ICT.

  • Prompt responses and evacuation prior to storm surge damage
  • Appropriate maintenance of floodgate facilities
