Abstract : Preoperational baseline characterizations and postoperational monitoring strategies associated with dredged material disposal in the coastal zone commonly document changes in sediment and benthic invertebrate communities inhabiting those sediments. The US Army Engineer Waterways Experiment Station is developing and field-testing a technique that uses benthic invertebrate community data to make quantitative statements about the feeding habitat value to fish of natural bottoms and bottoms modified by dredged material disposal or other activities influencing substrate quality. This technique facilitates the development of a quantitative impact statement using data on changes in the benthos related to project activities. Additionally it allows quantitative comparison to be made between areas being considered for disposal and/or other modification during project planning and uses a measure with social significance (i.e. , the potential productivity of the demersal fishery).
