全球重大洪水灾害典型案例数据集（2018.01-2018.12）

该数据集分析了2018-2019年全球典型洪水灾害事件的时空分布规律、影响及损失情况。2018年，全球洪水灾害发生次数共109起，死亡人口1995人，受灾人口总数达1262万人次，直接经济损失约为45亿美元，在全球近30年中处于较低水平。2018年全球洪灾事件发生次数上半年较下半年多，5月至7月发生频次较高。因此，以2018年美国弗罗伦斯飓风洪水、2018年尼日利亚尼日尔河洪水及2018年中国山东寿光洪水等三个典型灾害事件为案例，从灾害背景、致灾因子、受灾情况等方面进行了分析。This dataset analyzes the spatiotemporal distribution patterns, impacts and loss conditions of typical global flood disaster events during 2018-2019. In 2018, there were a total of 109 global flood disasters, resulting in 1,995 fatalities, a total of 12.62 million affected people, and direct economic losses of approximately 4.5 billion USD, which was at a relatively low level over the past 30 years worldwide. The number of global flood disasters in the first half of 2018 was higher than that in the second half, with a relatively high occurrence frequency from May to July. Therefore, three typical disaster events were selected as case studies for analysis from the aspects of disaster background, disaster-causing factors and affected conditions, including the Hurricane Florence flood in the United States in 2018, the Niger River floods in Nigeria in 2018, and the Shouguang floods in Shandong, China in 2018.
