ADDAMS
-
Set of continually evolving, state-of-the-art, computer-based tools that will increase the accuracy, reliability, and cost-effectiveness of dredged material management activities in a timely manner.
- A knowledge-based expert system (KBES) that provides an expert evaluation of the dredgeability characteristics of specific sediments whose geotechnical properties are described in the dredging contract documents. A KBES such as DREDGABL uses expertly derived rules for its solutions. The rules can incorporate and process judgment, experience, empirical rules of thumb, intuition, and other expertise as well as proven functional relationships and experimental evidence. The knowledge base contains a database of facts and a series of IF - THEN rule statements that include all of the questions a typical user may ask. Advice is also given about the suitability of various types of dredging equipment for use with those sediments, based on dredgeability characteristics. Expert knowledge is contained in several knowledge databases that are queried during operation of the program. DREDGABLE is intended for use by dredging project estimators and planners working with the US Army Corps of Engineers, dredging contractors, or dredging consultants. Inexperienced personnel
can learn from the guidance program. Also, knowledgeable and experienced personnel can benefit from consultation with their peers for review and as a check of their own work.
GEOtechnical SITE Investigation Methods (GEOSITE)
- Intended to provide guidance to geotechnical engineers, engineering geologist, and others in the selection of sampling and testing equipment for use at a single exploration site during a subsurface investigation for a dredging project. Inexperienced personnel can learn from the guidance program. Also, knowledgeable and experienced personnel can benefit from consultation with their peers for review and as a check of their own work.

TrophicTrace: A Tool for Assessing Risks from Trophic Transfer of Sediment-Associated Contaminants
-
TrophicTrace is an Excel™ add-in that provides a spreadsheet tool for calculating the potential human health and ecological risks associated with bioaccumulation of contaminants in dredged sediments.
