Stream network of Hanyang, a city of water

This study was conducted to investigate the stream network formed in Hanyang and the topographic features of the surrounding areas for the purpose of identifying the impact of Hanyang’s stream network on its city formation. To this end, three substudies were conducted: (i) Topographic restoration of late Joseon using a digitized map including the stream network of the Joseon period and a cadastral map; (ii) Identification and explanations of the discrepancies between the digitally restored stream network and the real stream network by superposing the former upon the latter; (iii) Identification of the Hanyang’s stream network on its urban structure. The results of this study can be summarized as follows: First, the waterways derived by GIS analysis and those on the 1912 Cadastral Map were verified to general coincide with each other, but some changed waterways were observed. Second, the watershed and administrative boundaries general coincided.
