Prema podacima studije iz maja 2025. godine, oko 10% grada tone brzinom ve\u0107om od tri milimetra godi\u0161nje, dok prose\u010dno sleganje u centralnim urbanim zonama iznosi oko dva milimetra godi\u0161nje.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Jedan od autora istra\u017eivanja, Manoochehr Shirzaei, obja\u0161njava da su uzroci kombinacija prirodnih procesa i ljudske aktivnosti. Me\u0111u prirodnim faktorima izdvajaju se postglacijalne izostatske promene \u2013 pomeranja tla nastala nakon topljenja ledenog pokriva\u010da. Ipak, zna\u010dajnu ulogu ima i dugogodi\u0161nje crpljenje podzemnih voda.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Podaci U.S. Geological Survey pokazuju da je nivo podzemnih voda u regionu od 1864. godine opao za \u010dak 900 stopa. Takav pad direktno uti\u010de na stabilnost tla, pove\u0107avaju\u0107i rizik za temelje zgrada, saobra\u0107ajnice i \u017eelezni\u010dku infrastrukturu.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Stru\u010dnjaci upozoravaju da su posebno osetljive zone poput River North, Loop, West Loop i South Loop, kao i oblasti uz \u017eelezni\u010dke trase. Iako se ne o\u010dekuju trenutne dramati\u010dne posledice, dugoro\u010dno sleganje mo\u017ee izazvati ozbiljna strukturna o\u0161te\u0107enja.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Kao potencijalno re\u0161enje predla\u017ee se sistem kontrolisanog vra\u0107anja vode u podzemne slojeve \u2013 tzv. \u201emanaged aquifer recharge\u201c. Ovakav model ve\u0107 daje rezultate u okrugu Orange County, gde je doprineo stabilizaciji tla i ubla\u017eavanju efekata su\u0161e.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Iako \u010cikago trenutno nema formalni program dopunjavanja podzemnih voda, gradske vlasti ula\u017eu u projekte zelene infrastrukture i upravljanje vodnim resursima. Nau\u010dnici poru\u010duju \u2013 problem je spor, ali dugoro\u010dan, i zahteva strate\u0161ko planiranje pre nego \u0161to posledice postanu vidljive.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:10px\">SOURCE: <a href=\"https:\/\/news.wttw.com\/2025\/09\/16\/chicago-among-major-us-cities-are-slowly-sinking-study\" target=\"_blank\" rel=\"noreferrer noopener\">WTTW<\/a>, PHOTO: PIXABAY<\/p>","protected":false},"excerpt":{"rendered":"<p>Novo istra\u017eivanje objavljeno u \u010dasopisu Nature Cities otkriva zabrinjavaju\u0107i trend \u2013 gotovo 98% teritorije grada \u010cikaga pogo\u0111eno je postepenim sleganjem tla, poznatim kao \u201eland subsidence\u201c.
