本文介绍了印度东海岸的气旋风模式和风暴潮和洪水模式。它们是最近在印度开发和实施的风暴潮和洪水预报系统的一部分。这些模型的结果被用来制作洪水图和潜在的风灾图的帮助下，GIS层。气旋风模型是基于荷兰的，并修改为目前的应用。设计了一种高分辨率的时间插值方案，该方案使用移动网格。这些概念和应用已经通过包括超级气旋奥里萨在内的一些实际案例进行了验证。提出了一种稳定、高效的陆上注水方法。结果表明，该模型能较好地再现涌浪淹没过程。还介绍了24小时运行系统的建立，包括通过卫星接收最新观测数据。
The present paper describes a cyclone wind model and storm surge and flooding model for the east coast of India. They form part of the operational Storm Surge and Flood Forecast System that was recently developed and implemented in India. Results from these models are used to produce flood maps and potential wind damage maps with the help of GIS layers. The cyclone wind model is based upon that of Holland, and was modified for the present applications. A high-resolution time interpolation scheme has been devised, which uses a moving grid. The concepts and the application have been validated using a number of actual cases including the super cyclone ORISSA. A stable and efficient overland flooding procedure is presented. It is shown that the surge and flooding model is able to reproduce the inundation with high degree of accuracy. The set-up of the 24 hours operational system that includes the receipt of up to date observational data through satellites is also presented.
