The principles and methods of harbor dredging surveys standards are explored in this paper. The Keelung Harbor dredging plan is taken as an example. The softwaves “Surfer” and “LeadSurvey” with the methodology of trapezoidal rule and average and area volume respectively are used for dredge volume computation. The comparisons of the difference between them are also made for further reference on practical work of harbor dredging surveys.
