摘要
基于1992—2021年降水观测数据和气象灾情数据,采用FloodArea模型对沁水经济技术开发区所在山谷地区不同重现期下的暴雨洪涝淹没范围进行模拟评估.结果表明:研究区所在地区不同重现期小时雨型呈多峰分布,山谷效应导致雨水汇流,淹没水深和面积增加,具有一定的暴雨洪涝风险;区内大部分淹没面积在10cm^(2)以下;内涝等级为一般性内涝风险(10~25cm)的淹没面积为0.48km^(2),主要呈散点状分布于研究区各片区;中度内涝风险(25~50cm)的淹没面积为0.41km^(2),主要呈散点状分布在端氏综合服务中心周围;严重内涝风险(50~80cm)的淹没面积较少,为0.32km^(2);特别严重内涝风险(>80cm)的淹没面积为4.74km^(2),主要集中分布于北部产业片区和南部产业片区的偏西地区.各重现期淹没风险较大的区域主要分布在各个片区内低洼地区,与实际灾情相符.
Based on the precipitation observation data and meteorological disaster data from 1992 to 2021,the Flood Area model is used to simulate and evaluate the inundation range of rainstorm and flood in the valley area where Qinshui Economic and Technological Development Zone is located under different return periods.The results show that the hourly rainfall patterns of the study area in different return periods are multi-peak distribution,and the valley effect leads to the rainwater confluence,the increase of submergence depth and area,which has a certain risk of rainstorm and flood.Most of the inundation area in the area is below 10 cm^(2).The inundation area of general waterlogging risk(10-25 cm)is 0.48 km^(2),which is mainly distributed in the study area in a scattered manner.The inundation area of moderate waterlogging risk(25-50 cm)is 0.41 km^(2),which is mainly distributed in the form of scattered points around the Duanshi Integrated Service Center.The inundation area of serious waterlogging risk(50-80 cm)is 0.32 km^(2).The inundation area of particularly serious waterlogging risk(>80 cm)is 4.74 km^(2),which is mainly distributed in the northern industrial area and the western part of the southern industrial area.The areas with high inundation risk in each return period are mainly distributed in low-lying areas in each area,which is consistent with the actual disaster situation.
