Columbia Estuary Data Development Program - Hydrodynamic Modeling of the Columbia River Estuary

The research reported in the following two volumes was funded primarily by CREDDP in two parts. The first part of the study employed the U. S. Army Corps of Engineers Waterways Experiment Station Implicit Flooding Model (WIFM). Thanks are due to Lee Butler of WES for supplying the original code for WIFM.

Columbia Estuary Data Development Program - Guide to the Use of CREDDP Information For Environmental Assessments

The Columbia River Estuary Data Development Program (CREDDP), a federally-funded research program, began in 1978 and was completed in 1984. The purpose of the program was to provide a foundation of scientific knowledge about the estuary and to provide information useful in managing land and water resources through the public planning and permitting processes.

Columbia Estuary Data Development Program - Dynamics of the Columbia River Estuarine Ecosystem, Volume 2

A major goal of this report is to provide an integrated presentation of Columbia River Estuary community dynamics in relation to physical processes. This chapter presents the conceptual model used in carrying out physical-biological integration. Problems in integrating CREDDP data and considerations in model selection are described (Section 6.1).

Columbia Estuary Data Development Program - Changes in Columbia River Estuary Habitat Types Over the Past Century

This study compares information on the Columbia River Estuary from a time predating most human impacts with corresponding information derived from recent sources. Section 2, Methods and Materials, describes the selection and use of materials to achieve this comparison. Surveys conducted from 1868 to 1873 are the source of the historical materials selected.
