Dampak pemanasan global, yaitu berupa kenaikan muka laut dengan kecepatan 2-8 mm/tahun yang tampaknya lambat dan tidak berarti, akan tetapi dalam 100 tahun mendatang kenaikan muka laut tersebut mampu untuk menggenangi kawasan pesisir P. Jawa yang memiliki morfologi pantai yang landai dan bersudut lereng kecil. Kenaikan muka laut merupakan bencana alam yang lambat dan bisa diprediksi, namun dengan sifat yang demikian justru manusia cenderung lupa segera menanganinya. Oleh karena itu, untuk mengantisipasi kemungkinan terjadinya bencana, serta mengurangi bahkan memperkecil dampak negatif risiko bencana tersebut, perlu memasukan komponen manajemen risiko bencana alam (risk management of natural disaster) di dalam penyusunan tata ruang wilayah (RTRW). Kata kunci: kenaikan muka laut, manajemen risiko bencana alam, Pulau Jawa, pesisir The impact of global warming, in the form of sea level rise by the rate 2-8 mm/year which seems slow and insignificant, but in the next 100 years sea level rise are can inundate coastal areas of Java which has a low slope beach morphology and small slope angles. Sea-level rise is a natural disaster that slow and predictable, but the nature of such people tend to forget it immediately. Therefore, to anticipate disasters and reduce or even minimize the negative impact of disaster risks, it is need to include components of risk management of natural disaster in the preparation of the spatial planning.

Abstract. Due to climate change an accelerated mean sea level rise is expected. One key question for the development of adaptation measures is how mean sea level rise affects tidal dynamics in shelf seas such as the North Sea. Owing to its low-lying coastal areas, the German Bight (located in the southeast of the North Sea) will be especially affected. Numerical hydrodynamic models help to understand how mean sea level rise changes tidal dynamics. Models cannot adequately represent all processes in overall detail. One limiting factor is the resolution of the model grid. In this study we investigate which role the representation of the coastal bathymetry plays when analysing the response of tidal dynamics to mean sea level rise. Using a shelf model including the whole North Sea and a high-resolution hydrodynamic model of the German Bight we investigate the changes in M2 amplitude due to a mean sea level rise of 0.8 and 10 m. The shelf model and the German Bight Model react in different ways. In the simulations with a mean sea level rise of 0.8 m the M2 amplitude in the shelf model generally increases in the region of the German Bight. In contrast, the M2 amplitude in the German Bight Model increases only in some coastal areas and decreases in the northern part of the German Bight. In the simulations with a mean sea level rise of 10 m the M2 amplitude increases in both models with largely similar spatial patterns. In two case studies we adjust the German Bight Model in order to more closely resemble the shelf model. We find that a different resolution of the bathymetry results in different energy dissipation changes in response to mean sea level rise. Our results show that the resolution of the bathymetry especially in flat intertidal areas plays a crucial role for modelling the impact of mean sea level rise.

Fast urbanization produces a large and growing population in coastal areas. However, the increasing rise in sea levels, one of the most impacts of global warming, makes coastal communities much more vulnerable to flooding than before. While most existing work focuses on understanding the large-scale impacts of sea-level rise, this paper investigates parcel-level property impacts, using a specific coastal city, Tampa, Florida, USA, as an empirical study. This research adopts a spatial-temporal analysis method to identify locations of flooded properties and their costs over a future period. A corrected sea-level rise model based on satellite altimeter data is first used to predict future global mean sea levels. Based on high-resolution LiDAR digital elevation data and property maps, properties to be flooded are identified to evaluate property damage cost. This empirical analysis provides deep understanding of potential flooding risks for individual properties with detailed spatial information, including residential, commercial, industrial, agriculture, and governmental buildings, at a fine spatial scale under three different levels of global warming. The flooded property maps not only help residents to choose location of their properties, but also enable local governments to prevent potential sea-level rising risks for better urban planning. Both spatial and temporal analyses can be easily applied by researchers or governments to other coastal cities for sea-level rise- and climate change-related urban planning and management.

The impact of the climate change and global warming has hit the entire world, particularly the coastal areas such as the Dumai coastal area which is mainly caused by the sea level rise. Sea level rise is one of the important global issue today. It has been caused by ice melting at the poles, climate extreme event, and land subsidence. This increases the vulnerability effect in coastal areas which threatens human life, especially those living in coastal regions. Sea level rise can be forecasted by satellite imagery like ENVISAT, Topex/ Poseidon, Jason1 and Jason2. Sea level rise was calculated using a linear regression. Monitoring of sea level rise in the sea of Dumai was conducted over a period of 21 years (1993-2014) by taking data from 6 stations. The results show that the average sea level rise reaching 5.33 mm/year happened in Dumai. The rate of SLR lies between 4.72 mm/year to 5.66 mm/year. In 2050, Dumai, Riau is predicted to have an additional sea level of 0.19 m, 0.46 m in 2100 and 0.72 m in 2150. based on the predicted results, dumai should prepare plans to mitigate the rising of sea levels.

Abstract. Due to climate change an accelerated mean sea level rise is expected. One key question for the development of adaptation measures is how mean sea level rise affects tidal dynamics in shelf seas such as the North Sea. Owing to its flat coastal areas, especially the German Bight (located in the south-east of the North Sea) will be affected. Numerical hydrodynamic models help to understand how mean sea level rise changes tidal dynamics. By definition models cannot represent all processes in overall detail. One limiting factor is the resolution of the model grid. In this study we investigate which role the representation of the coastal bathymetry plays when analysing the response of tidal dynamics to mean sea level rise. Using a shelf model including the whole North Sea and a high-resolution hydrodynamic model of the German Bight we investigate the changes in M2 amplitude due to a mean sea level rise of 0.8 m and 10 m. To the mean sea level rise of 0.8 m the shelf model and the German Bight Model react in different ways. In the shelf model the M2 amplitude generally increases in the region of the German Bight. In contrast, the M2 amplitude in the German Bight Model increases only in some coastal areas and decreases in the northern part of the German Bight. In two case studies we adjust the German Bight Model in order to more closely resemble the shelf model. We find that a different resolution of the bathymetry results in different energy dissipation changes in response to mean sea level rise. Our results show that the resolution of the bathymetry especially in flat intertidal areas plays a crucial role for modelling the impact of mean sea level rise in the order of 1 m. For higher mean sea level rise scenarios (10 m) the resolution of the bathymetry is less important.

This chapter focuses on the impacts of glacier melt on our oceans and related sea level rise. It discusses past and present sea levels and the relative influence of the ice age cycles. The chapter also reviews risks posed now to life on Earth due to glacier melt and related sea level rise, considering these in relation to ongoing and new flooding impacting coastal areas. It goes on to discuss the theories of Hot House Earth and Snowball Earth, the likelihood of these scenarios being realized, and the impact of high levels of CO2 concentrations on the likelihood of either eventuality.

Abstract The increase in sea levels, as a result of climate change in territorial aspect will have a potential impact on two major issues – maritime zones and land territory. The latter goes into the heart of the theory of the state in international law as it requires us to confront the problem of complete and permanent disappearance of a State territory. When studying these processes, one should take into account the fundamental lack of appropriate precedents and analogies in international law, especially in the context of the extinction of the state, which could be used for guidance in this respect. The article analyses sea level rise impact on baselines and agreed maritime boundaries (in particular taking into account fundamental change of circumstances rule). Furthermore, the issue of submergence of the entire territory of a State is discussed taking into account the presumption of statehood, past examples of extinction of states and the importance of recognition in this respect.
