Flood - kuyinqubo engokwemvelo zemvelo

Izinhlekelele zemvelo exhunywe ngenhla ezingeni ezivamile amanzi emfuleni, kwenzeka njalo. Kulesi sihloko, siyathola lapho sikwazi ukukhuluma ngesikhukhula, njalo lapho - phezu kukazamcolo. Ake uchaze ukuthi mkhuba ngamunye futhi ufunde izimbangela imvelaphi yabo.

Kunini futhi kungani kukhona kwafika

Igama elithi "isikhukhula" njengoba Russian bomdabu, abizwa ngokufanele futhi kahle ukuhunyushwa abadumile uVladimir Ivanovich Dal nge twist zanamuhla ngonyaka yansukuzonke bechitha yezinkathi ezithile emifuleni, okuyinto umphumela we incibilikiswa entwasahlobo ka iqhwa nemvula. Lokhu kuyinqubo ethatha isikhathi, okubangela nokwanda okuphawulekayo amazinga emfuleni, ephelezelwa ukukhululwa kwe-wesiteshi uzamcolo yayo izikhukhula.

kunqunywa ngokwesayense ukuthi izikhukhula - yilona eliphezulu ukuwedlula wonke ngonyaka, okuqukethwe amanzi omfula, ngezikhathi eziphindiwe isizini efanayo. Le nkathi ngokuvamile akhawunti ingxenye enkulu ukugeleza yonyaka, ngezinye izikhathi kuze 75-80%. Isikhathi, igagasi okuphambene, amanzi ongaphakeme - inkathi ezingeni leliphasi. Kuwo wonke unyaka ka emifuleni othile uhlobo, imodi namandla kuncike izici zezulu kwendawo kukhona ushintsho njalo lezinkathi yamanzi high and low.

seasonality izikhukhula

Fundzisisa entwasahlobo ukuncibilika iqhwa kubangela entwasahlobo tide, ephelezelwa kwatheleka okusheshayo futhi amanzi amaningi. Lesi simo esiyingqayizivele sibangelwa ngemva kobusika esivamile emifuleni eminingi enesithwathwa ezikhuluphalisiweyo ogeleza emathafeni. Emphilweni ezingeni amanzi entabeni avuke it is ngokuvamile kubangelwa ukuncibilika ehlobo kwezinguzunga zeqhwa neqhwa ezintabeni.

Cabanga izikhukhula ezithile zonyaka imifula egeleza ensimini ka-Russia, ukucacisa uhlobo amandla abo futhi imodi.

Emfuleni, okwenza ngendlov coniferous, amahlathi lezihlahla, ehlathini futhi asemaqeleni forb yasethafeni isiRashiya, iqhwa ezikhuluphalisiweyo owandile. Njengoba iningi olunzulu iqhwa ukuncibilika senzeka ngo-March no-April, ngenxa yalokho, ukwandisa izinga kuza ngesikhathi esifanayo. Izikhukhula entwasahlobo - kuyinto ukuvelela amanzi, okuyinto waphawula hhayi kuphela emifuleni isiRashiya, kodwa futhi ePoland, Canada, Alaska namazwe aseScandinavia. Kusukela ngemuva kokumiswa ezakhayo Ngokwesilinganiso, amazinga okushisa nsuku zonke umoya, kancane kancane ekuqaleni kuphakamisa izinga lamanzi. Khona-ke ukwandisa ukwanda ngejubane nakuba kungaze kube yinxenye ngosuku. Ngokushesha, amanzi labashone medium nemifula elincane kuze kufinyelele 2-3 amamitha, ezinkulu - up amamitha 20. ububanzi ngezinye izikhathi Spill ifinyelela 15-30 km. Bhalisiwe irekhodi ukuvelela ezingeni emfuleni oluhambisana azungeze 60 amamitha eMfuleni umfula iYangtze ngo-1876.

Ngo eningizimu yeRussia, emaqeleni kanye lulwimi ezingwadule, sikwazi ukukhuluma amanzi lokudla imvula. Nokho, inani elikhulu imvula kulezi zindawo futhi kwenzeka entwasahlobo, kanti izikhukhula kwenzeke ngesikhathi esifanayo. Esimweni sezulu zamazwekazi Eastern eSiberia emifuleni zinezikhathi iqhwa Inamandla futhi entwasahlobo uzamcolo, uyeza, ngenxa izici zezulu yesifunda, ngemva kwesikhashana - ngoMeyi. Futhi kule sezulu yezimvula ka ezindaweni ezinezinga lokushisa elithokomele zaseMpumalanga Ekude has njalo eyomile ebusika futhi ezimanzi, ehlobo nemvula. Ngakho-ke, imifula ezindaweni ubuswa ukudla imvula ehlobo phakamisa amanzi.

Ngamanye amazwi, isikhukhula - isici njalo izindawo zemvelo lapho imifula.

Isikhathi kukazamcolo

Ngo emifuleni encane uzamcolo Akuthathi izinsuku ezingaphezu kwezingu-20, ukufinyelela ezingeni eliphezulu kakhulu ngosuku 3-5th. Isikhathi ku emifuleni emikhulu ifinyelela izinyanga 2-3, ephakamisa isiqongo - 20-30 ngosuku. Njengomthetho, ukwehla yamanzi ihlala isikhathi eside izikhathi 3-5 kuka enzeke. Izikhukhula phezu kwemifula e isimo sezulu sifudumele kuhambisana ukukhululwa kwe-iqhwa. Ice drift uyaqhubeka emachibini amancane kufikela kuzinsuku ezingu-5, in ezinkulu - kufike ku-15.

Yini iyisikhukhula?

It ubhekwa into ehluke khulu. Kusukela njalo izenzakalo zemvelo ayikwazi kusengaphambili, futhi izikhukhula yilo futhi emele short-term kuyanda okusheshayo e izinga lamanzi, okungajwayelekile nezakonomeren. Ngamanye amazwi, ngokungafani izikhukhula, izikhukhula ezinkulu ezisheshayo singenzeka ngezikhathi ezahlukahlukene onyakeni. Sinenkosi akuhlangene ne imithetho izinqubo zokuphila kanye amadamu kungadalwa imvula noma snowmelt ngasiphi isikhathi sonyaka. Ezimvula ezinamandla ezenzeka, isibonelo, eNingizimu-mpumalanga Asia, kungabangela emfuleni izikhukhula ezingaphezu kwesisodwa ngonyaka. Isikhathi izikhukhula iphansi - kusukela kwamahora ambalwa kuya ezinsukwini ezimbalwa.

Izikhukhula: ngemiphumela ngesikhukhula noma isikhukhula

Ngakho, uzamcolo - iphethini yansukuzonke emifuleni elisezansi entwasahlobo ngenxa snowmelt nasemanzini kuyinto kuyanda okusheshayo amanzi emanzini efanayo ehlobo emva kwezimvula ezinkulu ezingalindelekile.

Empeleni, ukwanda kwamanzi - futhi okunengqondo noma ezingalindelekile - hhayi isikhukhula. Imiphumela ukuthi abangele izikhukhula nezikhukhula, isb. E. esikhukhulayo endaweni, lapho kungenzeka ngenxa ekuphumeni amanzi ezingeni emfuleni, futhi kuyokwenziwa kanjalo ngokuthi. Phenomenon okubangelwa ukwanda kwamanzi kungenziwa labizwa ngezindlela ezihlukahlukene kuye ngezinga of njalo, kulindeleke noma ngephutha.
