This bulletin contains six papers that provide details for each component of the Fraser Lowland Hydrogeology Project. The principal aims of the Project included: developing a groundwater-hydrogeology database; testing the efficacy of various geophysical techniques for mapping; and undertaking preliminary groundwater modelling. The first paper outlines the database structure, with emphasis on the methods developed for mapping aquifers & aquitards using a geographic information system. The next three papers describe research on using electromagnetic, seismic reflection, and ground penetrating radar methods for mapping Fraser Lowland aquifers. The fourth paper focuses on the Brookswood aquifer and the use of radar to identify critical hydro-stratigraphic relationships. The final paper outlines preliminary two- and three-dimensional groundwater flow models for the Fraser delta and the Brookswood aquifer. Includes author index.
