This report outlines processes influencing sediment transport and describes methods to use in developing a Sediment Erosion and Deposition Assessment SEDA at a site designated as a Superfund site. A SEDA is a complex procedure that overlaps multiple disciplines. Processes and properties that should be assessed include sediment characteristics, groundwater movement, surface water stresses, sediment loadings, anthropogenic activity, and weather and oceanographic influences. Historical data can also provide a long-term record on evolution of the system, which is not only critical in assessing sediment erodibility, but will also support conceptual site model development. The most successful SEDA studies have been guided by a technical review panel working with a Remedial Project Manager in SEDA development. Understanding of processes at a specific site, coupled with experience from other sites, is also critical to success.
