Impact of land use changes on runoff generation/routing:Case study in the upstream of Huangtaiqiao in Jinan City
摘要
Abstract
[Objective]In order to investing the impact of urbanization on watershed runoff generation/routing and reduce flood hazards,it is essential to analyze the relationship between runoff generation/routing and land use cover changes under different stages of urbanization.[Methods]The upstream of Huangtaiqiao in Jinan City is selected as the study area to analyze the runoff changes in the study area under different underlying surface conditions and rainfall scenarios by the SWMM(Storm Water Man-agement Model).Both long-term land use cover data and the CLUE-S model are used to get land use information at different sta-ges.[Results]The result show that:(1)It is predicted that the study area would steadily promote the development of urbaniza-tion in the northwest at an average speed of 1.51 km2/a in the future;(2)Urbanization shows a significant amplification effect on rainfall-runoff processes for storms with different return periods,and the response of peak flow to higher urbanization stage would be more significant;(3)Urbanization shows a more significant impact on the runoff generation and concentration process of rainfall with smaller return periods.In the future,rainfall with smaller return periods may also result in flood disasters,when the return period increased from 1 a to 5 a,the increase of peak flow at the higher urbanization stage is 27.59％higher than that of the lower urbanization stage.[Conclusion]In the past,with the continuous development of urbanization,the increase in con-struction land has led to an increase in urban flood control pressure It is estimated that the peak flow would continue to increase in 2030,the peak flow would occur earlier,and the risk of flood disaster may be reduced if more pipelines are installed and drainage capability increases in specific sections.关键词
