| Abstract: | The major geohazards in the underwater areas near Shanghai can be classified into direct, potential and artificial. These geohazards include scoured trough, slider, active sand wave, sand ridge, unstable slope, rapid-erosional and accumulation areas, shoal, reef, bur iedehannel and palaeo-depression, buried-bedrock, gas-changed sediment,'stiff shell stratum', fault and earthquake, human activity. The distribution, influence on engineering facilities and protection measures against them are discussed in the paper. |
