Plan of Study for the Puget-Willamette Lowland Regional Aquifer System Analysis,Western Washington and Western Oregon: A Contribution of the Regional Aquifer-System Analysis Program

摘要

The purpose of the report is to describe the objectives of the Puget-WillametteLowland RASA study, the approach, the major work elements, and the work schedule to attain these objectives. Because of the nature of the study, the work elements and schedule included in the report should be considered as a general guide that will be revised and updated periodically as information is compiled and new information is collected and analyzed. In order to meet the overall RASA program goals, the major objectives of the study are to: (1) describe the geologic framework, (2) describe the hydrogeologic characteristics of the regional aquifer system, (3) describe the regional ground-water flow system within each subarea and major controls on it, and (4) estimate the water budget for selected areas and use the information to estimate the regional water-budget relations, and (5) provide analytical capabilities necessary to allow for a synthesis of knowledge of the ground-water flow systems.
