Uninzi oonodoli abadala e-USA, eJamani naseBelgium kwindawo yokugcina impahla, ukuhanjiswa ngokukhawuleza!

Ukulungiswa kokuqala

Ngo-1885 i-Olmsted-designed-designed New York State Reservation e-Niagara yenziwa ipaki yelizwe yokuqala, kwaye ngokukhawuleza yaba yindawo edumileyo kubakhenkethi kunye nabasenyongweni bomtshato ukuze bajonge ubukhazikhazi basendle beeNgxangxasi zaseMelika kunye neeNgxangxasi ezinkulu zeHorseshoe ngaphaya komda waseCanada. Kodwa kwakukho ingxaki: IiNgxangxasi zaseNiagara zaziphelelwa ziindudumo. “Ugqatso lweengalo” lwamandla ombane okhulayo phakathi kwamazwe amabini angasentla luthetha ukuba mancinane amanzi awayequkuqela kwiingxangxasi macala omabini.

Emva kokuba iKhanada kunye ne-US basayine isivumelwano se-Niagara River Diversion ngo-1950, baxoxa ngezicwangciso ezininzi-kuquka ukuguqula i-Niagara ibe "yingxangxasi yamanzi" eyayiza kuqhutywa ngeeCawa kuphela-ngaphambi kokuba ivume ukuphambukisa akukho ngaphezu kwesiqingatha se-200,000 cubic feet yoMlambo waseNiagara. -ngomzuzwana ngamnye ukuhamba kwendalo kumbane wamanzi ngexesha leeyure zemini ngexesha elimiselweyo labakhenkethi.Oonodoli bezesondo bokwenyani

“Oko kuthetha ukuba ungaya kwiiNgxangxasi zaseNiagara ngexesha leKrisimesi, okanye nangaliphi na ixesha ebusika, yonke into oyibonayo sisiqingatha samanzi esihla phezu kweengxangxasi,” utshilo uMacfarlane.National Geographic. "Ezinye iikota ezintathu zijikeleza [iingxangxasi] kwiitonela zomdlalo." U-Elden Ring Melina Sex Doll

Isivumelwano sika-1950 sikwabeke isicwangciso sokuvala impembelelo ebalulekileyo yombane wamanzi kuMlambo iNiagara kunye neengxangxasi zawo ezidumileyo. Iinjineli zaseKhanada zawujika umlambo ube ngamacandelwana amancinane, ziqhushumba zaza zakrola unxweme lweeNgxangxasi zeHorseshoe, zawucutha kangangamakhulu eemitha ukuze zenze incopho engaqhawukiyo egqunywe ngumkhusane wamanzi obhityileyo, olinganayo ukuze kubonakale umthamo. I-"telecolorimeter" eyenziwe ngokwezifiso yanceda iinjineli zaqinisekisa ukuba ukuwa kwicala laseKhanada kuhlala kungumthunzi ofanelekileyo wombala oluhlaza okwesibhakabhaka. Ukuphinda ukukrola amacakana eHorsehoe Fall kunciphisa inkungu, ebisisikhalazo esiqhelekileyo sabakhenkethi. Ukufunxa unodoli wesondo

Abalondolozi baseMelika bacatshukiswa kukugxuphuleka kobume bendalo, kodwa iinjineli zachasa ngokubonisa ukuba iiNgxangxasi zeNiagara ngokwemvelo zikhukulisa iinyawo ezininzi ngonyaka nakanjani na—indawo ekuyo ngoku imalunga neekhilomitha ezisibhozo ukusuka phezulu ukusuka apho amanzi aqala khona ukutya i-Niagara Escarpment malunga ne-12,000 leminyaka eyadlulayo.

“Kodwa ukuba unamanzi amancinci kakhulu ahamba phezu kwayo, iingxangxasi azinakukhukuliswa ngokukhawuleza,” ucacisa ngelitshoyo uMacfarlane. Yeyiphi indlela engcono yokugcina iiNgxangxasi zaseNiagara, iinjineli zaxoxa, kunokucothisa nje ukuhamba kwamanzi kwiingxangxasi?
