HIDRALERTA is a forecast and early warning system for coastal and port regions capable of predicting emergency situations, as well as carrying out risk assessment. The system concentrates on evaluating wave overtopping and flooding scenarios. It uses offshore sea-wave and wind forecast data, as well as tide data, as input to determine wave overtopping at specific locations. The calculation of the mean overtopping discharge over a structure is made through artificial neural network tools and/or empirical formulae, which are able to define the spatial distribution of the flow behind the structure. The HIDRALERTA system is composed of four modules developed in Open Source Web Technology, mainly using the Python Language. The Warning System can be configured and adapted for specific scenarios. The system has been successfully tested for the Port and Bay of Praia da Vitória, Terceira Island, Azores, Portugal, and is now under development and being implemented at the ports of Madalena do Pico and S. Roque do Pico. This paper describes the work carried out to date on the system and its application to these two ports in the Pico Island, Azores.

HIDRALERTA是面向沿海和港口地区的预测和预警系统，能够预测紧急情况并进行风险评估。该系统专注于评估波浪超顶和洪水情况。它使用海上海浪和风力预报数据以及潮汐数据作为输入，以确定特定位置的海浪超标。通过人工神经网络工具和/或经验公式可以计算结构上的平均超顶流量，这些工具和模型可以定义结构后面的流的空间分布。HIDRALERTA系统由使用开源语言技术开发的四个模块组成，主要使用Python语言。可以针对特定情况配置和调整警告系统。该系统已经在葡萄牙亚速尔群岛的特塞拉岛的普拉亚维托里亚港和湾成功进行了测试，目前正在开发中，并已在Madalena do Pico和S. Roque do Pico港口实施。本文介绍了迄今为止在该系统上进行的工作及其在亚速尔群岛皮科岛的这两个港口的应用。
