Development of an integrated simulator for coastal space design and total space evaluation

作为海岸环境空间设计综合模拟器的子系统，本研究尝试开发了海岸大气与热舒适模拟器、近岸生态水质模拟器和风沙盐环境模拟器。在海岸大气环境与热舒适方面，我们对面向东京湾的一个海滩夏季的微气候进行了实地调查，并分析了海滩的大气特征。在此基础上，我们开发了一个海岸空气和热舒适模拟器，该模拟器已应用于海滩空间设计，特别是植被布局，海滩沙区等。关于近岸生态水质模拟器，我们在面向太平洋的东京湾和鹿岛海岸进行了实地观测，并成功地数值模拟了它们的基本特征。对于风沙和盐环境模拟器，我们在交通运输部羽崎海洋研究站进行了实地调查。数据分析的结果澄清了风吹盐颗粒和地下水盐对环境影响的各个方面。通过数值模拟，成功地再现了这些物理量的主要输运特征。

As subsystems of an integrated simulator for coastal environmental space design, in the present study, we have attempted to develop coastal atmospheric and thermal comfort simulator, nearshore ecological water quality simulator and wind-blown sand and salt environment simulator.Regarding coastal atmospheric environments and related thermal comfort, we performed field surveys on the micro-climate on a beach facing Tokyo Bay snmmer season, and analyzed the atmospheric characteristics on the beach. Based on these results we have developed a coastal atmospheric and thermal comfort simulator, which has been applied to a beach space design, especially for the layout of the vegetation, the beach sand area and others. In relation to the nearshore ecological water quality simulator, we carried out field observations both at Tokyo Bay and Kashima Coast facing the Pacific Ocean and have succeeded in numerically simulating their fundamental characteristics. For the wind-blown sand and salt environment simulator, we have executed field surveys at Hazaki Oceanographic Research Station of Ministry of Transport. The results of the data analyzes have clarified the various aspects of the environmental impacts due to the wind-blown salt particles and ground water salt. It has been succeeded to reproduced by numerical simulations the principal transport characteristics of these quantities.
