引言由于人们致力于开发海底资源,特别是油气资源,因此详细的海底测绘就日益显得必要了。要成功地安装岸外设施和管道需要有海底地形和沉积物的综合图;维护这些设施也需要具备由于诸如海流冲刷,沉积物的沉积和海底不稳定性等过程造成的潜在海底变化方面的知识。例如,密西西比三角洲岸外油气工业的开发受到上述若干自然过程的影响。 INTRODUCTION As people are committed to exploiting submarine resources, especially oil and gas, detailed submarine mapping becomes increasingly necessary. The successful installation of offshore facilities and pipelines requires a composite map of the seafloor topography and sediment; the maintenance of these facilities also requires knowledge of potential seafloor changes due to processes such as ocean scouring, sediment deposition and seafloor instability . For example, the development of the offshore oil and gas industry in the Mississippi Delta is affected by several natural processes described above.
