Columbia River Estuary Data Development Program: Guide to the Use of CREDDP (Columbia River Estuary Data Development Program) Information for Environmental Assessments

摘要

The Columbia River Estuary Data Development Program (CREDDP), a federally-funded research program, began in 1978 and was completed in 1984. In this Guide, the term 'environmental assessment' is used to refer to any estimate of how a development project might affect the estuarine environment. Only physical, chemical, and biological effects on the estuary are considered; economic and social factors are not discussed. The effects of development projects (including construction, diking, filling, dredging, riverflow management, etc.) range from those of small-scale projects, primarily direct effects on the development site itself, to the direct and indirect effects of large-scale projects, which extend from the development site to larger areas of the estuary.
