Colombia - emlanjeni ngokubaluleka. Uphi Colombia (emlanjeni)? Iimpawu lokuhamba kwamanzi

Colombia - umlambo, use e North America, emantla-ntshona yinxalenye lizwekazi. Ubude bayo 2 ophosa. Ayajika nge Washington, Oregon kunye British Columbia. Power ngokukhethekayo glacial; eziphelayo ngoku endalweni. utshintsho emfuleni ukuphakama ngokupheleleyo ongatshiyo nokubonelela ngeemeko ezilungileyo ephehla ugesi ngamanzi. Kungenxa kule ndawo ukuvelisa umbane ngendlela eyiyo.

wokungena kwemali

Colombia - esemlanjeni imibala ezintlanu, nto leyo eye nemingenela ngaphezu kwama-50.

• I inkulu kubo - Snake. Wakha emadamini ezininzi. Eyokuqala yaba Grand Coulee, Rock Island. An into umdla kukuba xa intlanganisela Snake River lide kakhulu, loo nto ikuvumela ukuba nayo ngokubanzi lokuloba kushishino. Ummandla isitya sayo ngeli xesha kune nobungakanani bubonke Columbia River.
• Uillamentt. Enye nemingenela inkulu. umlambo omkhulu waseUnited States: ibandakanya km 301. Kwemali, nesigubungelo wonke ummandla kaRhulumente ka-Oregon, Cascade Mountains, Coast Range. Xa ekudibaneni Columbia yayakhiwe e Portland - sixeko sikhulu.

• Kootenay. Kuthatha indawo e British Columbia, Idaho and lamntana. Kubalulekile njengoko isebe lomlambo. Ubude bayo kancinci km ngaphezulu kwama-700. Umthombo ibekwe kwi Biverfute (Ridge) kulandele amanzi isangqa ayahamba East Columbia, United States, baze babuyele eKhanada. Power ikhutshwa nge umkhenkce.

• Lake kuziphatha Oreille. I lesithathu ngobukhulu isebe lomlambo. Kwemali ngasentla Idaho, mpuma Washington kunye mpuma British Columbia. Length Panda Orey yi-209 kuphela km. It asuka womntana. Le ndawo iyonke isitya yi 66 ophosa (nazo zonke Horse).

ukusetyenziswa kwamanzi

Ukusetyenziswa kwamanzi Colombia - emlanjeni, emi kwindawo yesine phakathi kwabo bonke imithambo amanzi US. Ukuba sicinga flow, kuba yinkokeli epheleleyo phakathi imijelo yamanzi North American ukuba iyangena Pacific Ocean. Kwindawo apho adjoin Melika kunye Canada, amanzi ufikelela 2700 m / s. Ngenkulungwane yeshumi elinesithoba (1894), eli nani kummandla we Te Dulce banda izihlandlo amawaka - ukuya ku-35 000 m / s. Sele XX ngenkulungwane (1968), ukusetyenziswa kwamanzi liye lathotywa kakhulu - 340 m / s.

fish zifuduka

Njengoko ukuba, uphi Colombia, umlambo zizityebi intlanzi, ukuvuka kubo olwandle. abameli ezininzi eziphilayo zaselwandle, ezifana salmonids (rainbow trout, chinook, coho). Amaxesha amaninzi, iindwendwe kunye Intlanzi ukuba ukudada kula manzi izihlandlo ezimbalwa ebomini bakhe. Emva 1867 waqala ukwakhiwa mveliso, salmon yehlile kakhulu. Ngenxa yoko, umthetho ligqithise owalela bengena lokuloba.

Kakhulu ukufuduka intlanzi kuchaphazela kwakhiwa amadama kunye ifikile, leyo, kufanele kuphawulwe ukuba esisityebi kunene DC. River kuba intsingiselo elibuthathaka kwezinye iindawo. Oku kunciphisa inani Qhotsa kwi njengesihlambo zolwelo. Ngaphambili, uhambo lwabo ukusuka kolwandle wathabatha iiveki hayi ngaphezulu kwe ezintathu emlanjeni, kodwa ngoku eli nani liye landa ubuncinane kabini. Ezi nguqu temporal ukwanda kakhulu umngcipheko ukufa, nto leyo ekhokelela yokutshabalala. In efikelela kuyo umlambo omiweyo ziintlobo ezithile zeentlanzi ongasoze kuhla elwandle kwaye akakwazi ukuya kwelinye inxalenye amanzi ngenxa kumadama. Oku kunciphisa ngokubaluleka ubungakanani inani lazo.

Kukho uhlobo oluthile iintlanzi, abameli apho aphile phantsi ubushushu rhoqo flow kade. Isikakhulu ke zitya Qhotsa salmon. Yiloo nto eyabangela ukuba abasemagunyeni bathi- amkele umthetho ekukhuthazeni izilwanyana okuloba.

eziphilayo

Colombia - umlambo, nto leyo kakhulu emdaka. Ukongeza yenyukliya ngazo inkunkuma ukuwa kunye nezinye izinto ezinobungozi kunye khompawundi, ingakumbi, iarseniki, izinambuzane, biphenyls, iintsholongwane. Ngenxa kokusingqongileyo embi echibini kwaye intlanzi emlanjeni afumaneka a lot of ityhefu. Oku kuchaphazela kuphela inani izilwanyana zasemanzini kwaye kunegalelo kwezinto eziphilayo, kodwa Ayize nakanye impilo umntu ayisebenzise. Ngubani rhoqo isebenza ukuphucula umgangatho wamanzi uze ubuyisele intsalela yendalo.

Ngokutsho Columbia River mveliso (photo ibhalwa kwinqaku) ibekwe kuqala kwi-US kunye Canada. Ku yakhiwa izityalo lombane 14. Kudala kwaziwa ukuba ngexesha lezikhukula, wathulula phezu umgama omde, nto nezikhukhula indawo yonke elijikelezileyo.

Utshintsho ebalulekileyo yenziwa Roosevelt, umongameli karhulumente. Walitshintsha emlonyeni, waqalisa ulwakhiwo Idama ekuqaleni kwenkulungwane XX. Emva ekwakhiweni kwayo kwinqanaba amanzi ngaphezulu kwe-100 m. Oku kuyenzeka ukuba wenze ichibi.
