San Juan National Historic Site, San Juan, Puerto Rico; Design for Prevention of Wave-Induced Erosion; Hydraulic Model Investigation

摘要

A 1:75-scale (undistorted) hydraulic model of the San Juan National Historic Site, which included the entire historic site, the entrance to San Jaun Harbor, part of Isla de Cabras, and sufficient offshore area in the Atlantic Ocean to permit generation of the required test waves, was used to investigate the effects of proposed structures on wave attack at the historic site. Proposed improvement plans consisted of the installation of rubble-mound revetments and/or breakwaters on both the ocean and bay sides of El Morro Castle. A 90-ft-long wave generator and an automated data acquisition and control system (ADACS) were utilized in model operation.
