摘　　要：广东省沿海平原中小河流具有比降缓、潮汐影响大、淹没范围广和堤围密集等特点,其淹没图编制至今无统一方法。该文通过Mike21和Arcgis软件,结合河流特性,参考《山丘区中小河流洪水淹没图编制技术指引》,以乌坎河为例探求出一种适用于广东省沿海平原中小河流的淹没图编制方法。该方法具有可操作性强、准确性较高和适用范围较广等特点,为后续广东省沿海平原中小河流淹没图制作提供参考。The Mid-small River in the coastal plain of Guangdong province have the characteristics of slow gradient,large tidal influence,wide inundation range and dense dike-encrustation,there is no unified method for the compilation of Making Flood Inundation Map.Based on Mike21 and Arcgis software,combined with river characteristics and referring to the“Technical Guidelines for Making Flood Inundation Maps of Mid-small River in Hilly Areas”,this paper explores a method for the compilation of inundation maps for small and medium-sized rivers in the coastal plain of Guangdong Province by taking Wukan River as an example.This method has the characteristics of strong operability,high accuracy and wide application range,and provides a reference for the subsequent production of Mid-small River Flood inundation maps in the coastal plain of Guangdong Province.
