Abstract:

Since the mid-19th century, sea level has been rising, likely primarily as a result of human-induced climate change. During the 20th century, sea level rose about 15-20centimeters (roughly 1.5 to 2.0 mm/year). The increasing rate at the end of the 20 century has been much greater than the first years of century [1, 2].There are three major processes by which human-induced climate change directly affects sea level. First, the thermal water expansion due to increasing temperature contributes to sea level rise. Thermal expansion is likely to have contributed to about 2.5 cm of sea level rise during the second half of the 20th century, with the rate of rise due to this term having increased to about 3 times this rate during the early 21stcentury. A second, and less certain, contributor to sea level rise is the melting of glaciers and ice caps. The third process that can cause sea level to rise is the loss ofice mass from Greenland and Antarctica. While there are obviously many challenges to projecting future sea level rise, even a seemingly small increase in sea level canhave a dramatic impact on many coastal environments [3]. According to the IPCC, even the best-case scenarios indicate that a rising sea level would have a wide range of impacts on coastal environments and infrastructure. Effects are likely to include coastal erosion, wetland and coastal plain flooding, salinization of aquifers and soils [4]. By these reasons sea level changes is a key issuein design of marine structures. In literature the relation between climatic variables and sea level changes is demonstrated. In this paper, an ANN model is developed to relateclimate signals simulated under climate change effects with sea level changes at the south of Iran.
