Monitoring of aquatic dredged material disposal sites may require a variety of physical and biological tools and techniques. Chemical monitoring tools and techniques are not discussed in this report since this document does not address chemically unsuitable material. In the tiered approach discussed in the companion report Guidelines for Physical and Biological Monitoring of Aquatic Dredged Material Disposal Sites, the lower level tiers may examine primarily physical changes at a site. Changes in physical environment, such as mounding, can result in a navigation hazard or lead to changes in the biological community e.g., burial, which necessitates biological monitoring. Design of a monitoring program must consider what equipment to use and at what spatial and temporal frequency to sample. These factors will be determined by the level of information required for the question being addressed, given present technical, monetary, regulatory, and political considerations.
