Dayactirka ugu horreeya

1885-kii Olmsted-naqshadeynta New York State Reservation ee Niagara ayaa laga dhigay beerta ugu horreysa ee waddanka, waxayna si dhakhso ah u noqotay meel caan ah oo loogu talagalay dalxiisayaasha iyo malab-yaasha si ay u eegaan quruxda duurjoogta ah ee Falls American iyo Horseshoe Falls oo ku yaal xadka Kanada. Laakiin waxaa jirtay dhibaato: Falls Niagara waxay lumisay onkodkeeda. Kororka tamarta biyaha ee "tartanka hubka" ee u dhexeeya labada waddan ee kacdoonku waxay ka dhigan tahay in biyo ka yar sidii hore ay ku qulqulayeen dayrta labada dhinac.

Ka dib markii Kanada iyo Maraykanku ay saxiixeen heshiiskii Weecinta Wabiga Niagara ee 1950, waxay ka wadahadleen qorshayaal badan - oo ay ku jiraan in Niagara loo rogo "biyo-dhac aan kala go' lahayn" oo socon doona oo keliya Axadaha - ka hor inta aysan ku heshiin in la leexiyo wax ka badan kala bar webiga Niagara ee 200,000 cubic feet -ilbiriqsikiiba socodka dabiiciga ah ee tamarta biyaha inta lagu jiro saacadaha maalintii inta lagu jiro xilliga dalxiiska ee loo qoondeeyay.

"Taasi waxay la macno tahay haddii aad aadi lahayd Niagara Falls wakhtiga Kirismaska, ama wakhti kasta oo jiilaalka, waxa kaliya ee aad arkayso waa rubuc ka mid ah biyaha oo dul maraya biyo-dhacyada," Macfarlane ayaa u sheegayNational Juqraafiga. "Saddexda rubuc ee kale waxay ku wareegayaan [dhacdooyinka] ee tunnel-ka leexinta." Elden Ring Melina Sex Doll

Heshiiskii 1950kii waxa kale oo uu dejiyey qorshe lagu qarinayo saamaynta weyn ee tamarta biyaha ee webiga Niagara iyo dhicitaankeeda caanka ah. Injineero Canadian ah ayaa webiga u leexiyay qaybo yaryar, iyagoo qarxinaya oo xardhay qararka Falls ee Horseshoe, iyaga oo boqollaal cagood ku yaraynaya si ay u abuuraan xadhig aan go'ayn oo ay ku daboolan yihiin daah dhuuban, lebbisan oo biyo ah si ay u muujiyaan mugga. "telecolorimeter" oo si gaar ah loo dhisay ayaa ka caawiyay injineerada inay hubiyaan dhicitaannada dhinaca Kanadiyaanka ah inay weli yihiin hadh sax ah oo buluug cagaaran ah. Dib-u-qaabaynta Dhabarka Horsehoe Fall waxay yaraysay ceeryaamo, taasoo ahayd cabasho dalxiis oo caadi ah.

Ilaaliyeyaasha Mareykanka ayaa ka xanaaqay faragelinta juqraafiyeed, laakiin injineerada ayaa ka soo horjeestay iyaga oo tilmaamaya in Niagara Falls ay si dabiici ah u baabi'iso dhowr cagood sanadkiiba si kastaba-meesha ay hadda ku taal ayaa ah ilaa siddeed mayl kor u kac ah halka ay biyuhu bilaabeen inay cunaan Niagara Escarpment qiyaastii 12,000 oo sano ka hor.

"Laakin haddii aad haysato biyo aad u yar oo dul maraya, dhicitaanku si dhakhso ah uma baabi'i karaan," Macfarlane ayaa sharaxay. Waa maxay habka ugu wanaagsan ee lagu ilaalin karo Falls Niagara, injineeradu waxay ku doodeen, in ka badan in si fudud loo yareeyo qulqulka biyaha ee dayrta?
