本文总结了最近对葡萄牙西海岸110公里长的沙质海岸河段的研究结果。该研究的最终目标是设计一个涵盖所有延伸的海上防御总体规划，并将在长期内建立。长期以来，这条海岸一直处于强烈的侵蚀过程中。对这个问题的历史和现状进行了深入的分析。不同的技术，涉及到一般问题的不同方面（波浪气候、沿海运输、绕沙、在侵蚀或侵蚀条件下的长期演变、腹股沟场、螺旋海滩等）。在沿海运输和沙土方面，尝试了绕过现有方法的改进。人们感到需要一种精确定义的波浪气候；一些相当令人失望的结果肯定与缺乏准确的波浪数据有关。
This paper summarizes a study recently concluded of a sandy coastal reach, 110 km long, on the Portuguese west coast. The final objecti ve of that study was the design of a sea defense master plan covering all the stretch, to be built at a long term. That coastal reach has been under a strong erosion process for a long time. The history of the problem and its present situation were thoroughly analysed. Different techniques, related to different aspects of the general problem (wave clima te, littoral transport, sand bypassing, long term evolution under accre tion or erosion conditions, groin field, spiral beaches, etc.lwere used. In what concerns littoral transport and sand bypassing the improvement of currently available methods was tried. The need of an accurately defined wave climate was felt; some rather disappointing results can sure ly be related to the lack of accurate wave data.
