Estimating and Visualizing Marine Dredge Quantities Using ArcGIS

Coastal dredging projects require an understanding of the quantity of soil to be removed during dredging operations. This involves the development of dredging limits, dredge depths, over-dredging, and uniform or composite dredge slopes that is established by marine/coastal engineers. GIS can be a valuable tool in visualizing and determining these dredging parameters. GIS also provides the capability to determine preliminary dredge quantities in addition to providing 3D visualizations of the dredge channel. For several projects in the Curtis Island/Gladstone area of Queensland, Australia, GIS was used as a tool to establish preliminary dredge quantities and view the results in a 3D scene. ArcGIS 3D Analyst and Spatial Analyst tools were used to streamline a complicated process to determine dredge quantities. This paper presents a method of using GIS as a tool for estimating dredge quantities and visualizing the results.
