Land subsidence due to groundwater withdrawal: potential damage of subsidence and sea level rise in southern New Jersey, USA

摘要: Land subsidence due to groundwater withdrawal combined with a global sea level rise creates serious environmental problem in the coastal region. Groundwater results fluid pressure change layers. The layers induces both elastic and inelastic land compaction. compaction can be recovered if water rises again becomes permanent. response barometric is used estimate this study. storativity, specific storage other layer hydrological information are of withdrawal. discussed methods applied predict potentials resulting from overdrafting southern New Jersey. estimated about 2–3 cm near location monitoring wells Atlantic, Camden, Cumberland Cape May Counties over past 20 years. If current trend water-level drop continues, average Jersey vicinity some will 3 next 2 mm/year on average. Because very gentle slope NJ, combination translate into potentially substantial amount loss region each year period. This also accelerate flooding frequency erosion rate plain, pose threat economy.
