Impacts of Sea Level Rise on the Coastal Areas to the West of the Bohai Bay

摘要

Based on the assumption of global sea level rising between 30 and 100 cm in the future 100 years by IPCC (1990) in addition to the effect of local ground subsidence, the coastline will retrograde for 50-70 km whose altitudes will be 2.6-3.3m above MSL of Huanghai Sea in the western coastal area of he Bohai bay in 2100. The transgrassive area is about 10,000-11, 500 km If the effect of set-up of storm surge is considered, the transgrassive area will reach 16,000 km. Sea level rise which is a serious coattail disaster to only inundates a lot of coastal lowland, but also incases he frequency and intensity of storm tides, and results in the salinization of soils. In vies of this situation we recommend a trinity comprehensive measure of treatment, namely, "building seawall to prevent tide--diverting the Hunaghe River to settle its sediment loads - raising the constructional base".
