Scenario Simulation-Based Assessment of Trip Difficulty for Urban Residents under Rainstorm Waterlogging

In this study, an experiment was performed to assess the trip difficulty for urban residents of different age groups walk<em>ing in various depths of water,</em> and the data were corroborated with the real urban rainstorm waterlogging scenarios in downtown (Daoli distric...

Mathematical models of urban rainstorm waterlogging were constructed using scenario simulation methods, aided by the GIS spatial analysis technology and hydrodynamic analysis of the waterway systems in the study area. Then these models were used to evaluate the impact of waterlogging on the safety of residents walking in the affected area. Results are summarized as: (1) for an urban rainstorm waterlogging scenario reoccurring <em>once every 10 years, three grid regions would have waterlogging above </em>0.5 m moving at a velocity of 1.5 m/s. Under this scenario, waterlogging would accumulate on traffic roads only in small areas, affecting the <em>safety</em> and mobility of <em>residents</em> walking in the neighborhood; (2) for an urban rainstorm waterlogging scenario reoccurring <em>once every 20 years</em>, 13 grids <em>experienced the same waterlogging situation</em> affecting a larger area of the city; (3) for an urban rainstorm waterlogging scenario reoccurring <em>once every 50 years, </em>86 grid regions were affected (<em>waterlogging above </em>0.5 m moving at 1.5 m/s), and those areas would become impassable for residents.

Then these models were used to evaluate the impact of waterlogging on the safety of residents walking in the affected area. Results are summarized as: (1) for an urban rainstorm waterlogging scenario reoccurring <em>once every 10 years, three grid regions would have waterlogging above </em>0.5 m moving at a velocity of 1.5 m/s. Under this scenario, waterlogging would accumulate on traffic roads only in small areas, affecting the <em>safety</em> and mobility of <em>residents</em> walking in the neighborhood; (2) for an urban rainstorm waterlogging scenario reoccurring <em>once every 20 years</em>, 13 grids <em>experienced the same waterlogging situation</em> affecting a larger area of the city; (3) for an urban rainstorm waterlogging scenario reoccurring <em>once every 50 years, </em>86 grid regions were affected (<em>waterlogging above </em>0.5 m moving at 1.5 m/s), and those areas would become impassable for residents. scenario simulation urban rainstorm waterlogging GIS trip difficulty Ha-Erbin City Medicine R Yulong Bao verfasserin aut Xinyu Jiang verfasserin aut Xingpeng Liu verfasserin aut Jiquan Zhang verfasserin aut Peng Chen verfasserin aut In International Journal of Environmental Research and Public Health MDPI AG, 2005 9(2012), 6, Seite 2057-2074 (DE-627)477992463 (DE-600)2175195-X 16604601 nnns volume:9 year:2012 number:6 pages:2057-2074 https://doi.org/10.3390/ijerph9062057 kostenfrei https://doaj.org/article/8bf6f144c8744764b1b5a9dd702f433b kostenfrei http://www.mdpi.com/1660-4601/9/6/2057 kostenfrei https://doaj.org/toc/1660-4601 Journal toc kostenfrei GBV_USEFLAG_A SYSFLAG_A GBV_DOAJ GBV_ILN_20 GBV_ILN_22 GBV_ILN_23 GBV_ILN_24 GBV_ILN_39 GBV_ILN_40 GBV_ILN_60 GBV_ILN_62 GBV_ILN_63 GBV_ILN_65 GBV_ILN_69 GBV_ILN_70 GBV_ILN_73 GBV_ILN_74 GBV_ILN_95 GBV_ILN_105 GBV_ILN_110 GBV_ILN_151 GBV_ILN_161 GBV_ILN_170 GBV_ILN_206 GBV_ILN_213 GBV_ILN_224 GBV_ILN_230 GBV_ILN_285 GBV_ILN_293 GBV_ILN_370 GBV_ILN_602 GBV_ILN_2014 GBV_ILN_2153 GBV_ILN_4012 GBV_ILN_4037 GBV_ILN_4112 GBV_ILN_4125 GBV_ILN_4126 GBV_ILN_4249 GBV_ILN_4305 GBV_ILN_4306 GBV_ILN_4307 GBV_ILN_4313 GBV_ILN_4322 GBV_ILN_4323 GBV_ILN_4324 GBV_ILN_4325 GBV_ILN_4338 GBV_ILN_4367 GBV_ILN_4700 AR 9 2012 6 2057-2074

abstract	In this study, an experiment was performed to assess the trip difficulty for urban residents of different age groups walk<em>ing in various depths of water,</em> and the data were corroborated with the real urban rainstorm waterlogging scenarios in downtown (Daoli district) Ha-Erbin (China). Mathematical models of urban rainstorm waterlogging were constructed using scenario simulation methods, aided by the GIS spatial analysis technology and hydrodynamic analysis of the waterway systems in the study area. Then these models were used to evaluate the impact of waterlogging on the safety of residents walking in the affected area. Results are summarized as: (1) for an urban rainstorm waterlogging scenario reoccurring <em>once every 10 years, three grid regions would have waterlogging above </em>0.5 m moving at a velocity of 1.5 m/s. Under this scenario, waterlogging would accumulate on traffic roads only in small areas, affecting the <em>safety</em> and mobility of <em>residents</em> walking in the neighborhood; (2) for an urban rainstorm waterlogging scenario reoccurring <em>once every 20 years</em>, 13 grids <em>experienced the same waterlogging situation</em> affecting a larger area of the city; (3) for an urban rainstorm waterlogging scenario reoccurring <em>once every 50 years, </em>86 grid regions were affected (<em>waterlogging above </em>0.5 m moving at 1.5 m/s), and those areas would become impassable for residents.

Mathematical models of urban rainstorm waterlogging were constructed using scenario simulation methods, aided by the GIS spatial analysis technology and hydrodynamic analysis of the waterway systems in the study area. Then these models were used to evaluate the impact of waterlogging on the safety of residents walking in the affected area. Results are summarized as: (1) for an urban rainstorm waterlogging scenario reoccurring &lt;em&gt;once every 10 years, three grid regions would have waterlogging above &lt;/em&gt;0.5 m moving at a velocity of 1.5 m/s. Under this scenario, waterlogging would accumulate on traffic roads only in small areas, affecting the &lt;em&gt;safety&lt;/em&gt; and mobility of &lt;em&gt;residents&lt;/em&gt; walking in the neighborhood; (2) for an urban rainstorm waterlogging scenario reoccurring &lt;em&gt;once every 20 years&lt;/em&gt;, 13 grids &lt;em&gt;experienced the same waterlogging situation&lt;/em&gt; affecting a larger area of the city; (3) for an urban rainstorm waterlogging scenario reoccurring &lt;em&gt;once every 50 years, &lt;/em&gt;86 grid regions were affected (&lt;em&gt;waterlogging above &lt;/em&gt;0.5 m moving at 1.5 m/s), and those areas would become impassable for residents.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">scenario
