Surveying and monitoring are two separate processes, both of which have an essential role in dredging operations.
Surveying
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.
Monitoring
Monitoring of a project is an exercise in quality and quantity control to determine if a dredging operation is meeting the performance requirements that have been stipulated. Monitoring will determine in land reclamation projects, if the quality of fill is suitable for the purpose of the project; in deepening channels, if the correct depths have been dredged; and in all cases, if a project fulfils the environmental requirements.
