Abstract

本发明公开了一种城市内涝模拟分析方法，城市的内涝积水预测建模：本发明的有益效果是对城市内涝模拟效果较好，有助于洪涝灾害的防控，可有效提高城市的信息预警能力。

Description

一种城市内涝模拟分析方法
技术领域
本发明属于气象技术领域，涉及一种城市内涝模拟分析方法。
背景技术
近年来，极端气候不断出现，导致暴雨多发、城市内涝问题突出，严重威胁城市市民的生命财产安全。因此，建立城市降雨积水监测网络，实时了解城市的降雨和积水问题，预防城市内涝成为亟待解决的民生问题。建立城市内涝模拟***，有助于洪涝灾害的防控，可有效提高城市的信息预警能力。
发明内容
本发明的目的在于提供一种城市内涝模拟分析方法，本发明的有益效果是对城市内涝模拟效果较好，有助于洪涝灾害的防控，可有效提高城市的信息预警能力。
本发明所采用的技术方案是城市的内涝积水预测建模：
其中，yj(t)是雨量j站点t时刻的降雨量，n为受影响的雨量站点个数，θi，ρi是模型的参数，λji第j站点对应的参数，εi(t-1)是t-1时刻随机正太误差分布向量。
附图说明
图1是太白湖区5、10、15min积水预测值示意图。
具体实施方式
下面结合具体实施方式对本发明进行详细说明。
城市的内涝积水预测建模：
其中，yj(t)是雨量j站点t时刻的降雨量，n为受影响的雨量站点个数。
其中，θi，ρi是模型的参数，λji第j站点对应的参数。εi(t-1)是t-1时刻随机正太误差分布向量。
根据在济宁太白湖区采集的步长为6分钟的内涝积水对建立的模型的预测性能进行进行评价，评价结果如图1所示。相对平方误差RSE、方根误差RMSE和相对误差比率RE被应用于不同时间评价结果的准确度测量。从结果可以看出，建立的模型的预测准确度较高。太白湖的内涝积水时间跨度较长，历时4个小时，预测精度误差在3％左右。
以上所述仅是对本发明的较佳实施方式而已，并非对本发明作任何形式上的限制，凡是依据本发明的技术实质对以上实施方式所做的任何简单修改，等同变化与修饰，均属于本发明技术方案的范围内。
