Monitoring Land Use/Cover Changes by Using Multi-Temporal Remote Sensing for Urban Hydrological Assessment: A Case Study in Beijing, China

Understanding the change in hydrological response due to urban dynamics is important for better flood preparedness and future sustainable planning. This study investigated influence of land cover on spatiotemporal changes peak discharge volume within a rapidly urbanizing catchment located Beijing, China. We used Landsat satellite data ranging from 1986 2017 monitor quantify growth. Moreover, Hydrological Modeling System (HEC-HMS) coupled with meteorological was utilized examine impact growth responses. The results revealed that major use/cover (LULC) were detected landscape, which increased 25.22% 65.48% total area, while agricultural decreased 64.85% 25.28% during 1986–2017. average three rainstorms events reached 7.02% 11.93%, respectively. Furthermore, more obvious at sub-catchment scale. These findings indicate enhanced possible flooding risk catchment. improves understanding isolated impacts urbanization provides essential information
