A Mathematical Analysis of the Subsidence in the Long Beach - San Pedro Area

This report presents the significant results from a mathematical study of the subsidence in the Long Beach area. The work, begun in December 1949 at the request of Mr. M.D. Hughes, Chief Petroleum Engineer, the Petroleum Division of the Long Beach Harbor Department, has been in progress for two years. During this period a large volume of physical data pertinent to the subsidence phenomena has been made available and analyzed. Additional tests suggested by the mathematical analysis have been instigated by the Petroleum Division so that a well integrated program of research has been brought to bear upon this problem.
