Survey

Surveys are conducted as a part of a project to define the characteristics of soils and subsoils at the dredging site and/or borrow area. Surveys will determine characteristics of the marine surroundings, such as water depth, currents, waves, temperature, salinity, wind, turbidity, TSS and types of sediment. It helps to determine the total amount of soil which must be removed from a particular area, both for capital (new projects) and maintenance dredging, also helps to check if the design depth has been reached over the entire area after dredging has occurred.
