Ngozi hydrodynamic

Chimodzi mwa zitsanzo chidwi kwambiri pa ngozi hydrodynamic wakhala chochitika mu California, makilomita makumi asanu ndi awiri okha kuchokera Los Angeles (San Francisco Canyon). The mosungiramo anayamba kudzaza mu 1972, koma mlingo wokweretsa wakhala anafikira mu chaka. Madzi akulowa kudzera damu la chifukwa nkhawa ngakhale ndiye, koma kulira kwa m'deralo akuluakulu samva. Vuto anabwera mu 1928, March 12. Ndi damu sanakhale ndi moyo kuthamanga kwa madzi, anagumula strata nthaka, ndipo inagwa. 40 mita yaitali mpanda wa madzimadzi ananyamula amagetsi anamanga mu 25 Km pambuyo Mphindi 5. zamoyo zonse pamodzi ndi nyumba anawonongedwa. The otaya unali m'chigwa. Apa mphamvu zake pang'ono ofooka, koma anapitiriza ulendo wake kuti adzacotsa zonse, kusamukira ku Saroni. Ndi nthawi iyi anali kale zitatu kilometre matope otaya amene anapha anthu asanu ...

ndi mitundu ya ngozi hydrodynamic chiyani? Ndingapewe bwanji iwo?

Hydrodynamic ngozi makamaka zodziwikiratu, ndi zodziwikiratu, koma kusasamala munthu kumawachititsa kuchitika. Kalanga ine, chinthu chachibadwa mu mawonekedwe a zivomezi, mikuntho, kugumuka, zigumukire ndi madzi osefukira amakhala ndi chifukwa cha tsokalo ndi n'kukhala kwambiri kuposa chinthu anthu. ngozi Hydrodynamic kuchitika kawirikawiri chifukwa zolakwa kapangidwe zopindika yomanga kamangidwe, chophwanya malamulo a ntchito, spillways kuchepa ndi kusefukira kwa madzi damu la. Komanso, musaphonye mwayi zochita zonyoza zimayenda ndi kutema ndi maofesi amenewa.

ngozi Hydrodynamic ndizo zotsatira za kulephera kwa nyumba hayidiroliki, chifukwa mu amavutitsa otaya wamphamvu waukulu wa madzi ndi liwilo zimabwerera gawo lalikulu, onyamula kuwonongedwa ndi imfa. M'dera anasefukira agawidwa mabacteria 4.

Woyamba ili umakhala pafupi zomangamanga madzi ndi utali wozungulira wa makilomita 12 kuchokera izo. Liwiro ndi kutalika kwa otaya chimadalira pa chikhalidwe cha kuwonongeka kwa nyumba hayidiroliki, chidzalo awo pamaso ngozi ndi kutalika pamwamba pa nyanja. Panopa kuwonongedwa kwa wofuna kwambiri.

Mu mabacteria wachiwiri ndi wachitatu otaya mathamangidwe ndi kutalika kwa funde la amachepetsa kwambiri (zoopsa pano ali m'mayiko ambirimbiri zizindikiro mtunda: mapiri, zigwa, madambo, etc.).

Zoni chachinayi monga m'dera la utuluke ofooka, pamene mathamangidwe pafupifupi 8-9 Km / h, kutalika zimadalira mpumulo m'dera anasefukira.

Zinali malo oyamba kumene ataya moyo ndi chiwonongeko chidzachitika (ndipo kawirikawiri - chiwonongeko chotheratu) maofesi amaonedwa m'madera chigumula.

Kodi ngozi hydrodynamic zitheka mu Russia? Nokha. Dziko wamanga zikwizikwi Madamu, mphamvu makumi asanu a iwo - oposa biliyoni kiyubiki mamita. Yosungirako zinyalala mafakitale ndi zimbudzi - kakhumi. Ndipo onse a iwo - zikanavulaza zinthu. Zikuphatikizapo osati yokumba nyumba (maiwe mchere, madamu, levees, uyenderere akasinja, etc.) Koma mapangidwe zachilengedwe ndi kusintha madzi (kumtunda / pambuyo pake). Information: 300 yololedwa mwalamulo ngozi madamu pa zapitazi zana ndi makumi asanu, kuposa 30% zinachitika chifukwa mowa owonjezera zinyalala.

Zitsanzo za masoka amenewa pa gawo la Chitaganya cha Russian, mwatsoka, ambiri: 1993 - Kisielewski mosungiramo (damu yopuma), 1994 - Tirlyan mosungiramo, p. White (chiwonongeko cha damu la), 1994 - Primorye (chigumula), 1999 - Yakutia (ndi tsoka akubwerezedwa pambuyo zaka ziwiri), 2002 - dera Krasnodar (kusefukira kwa madzi komanso kuwonongedwa kwa matamanda a madzi).

Tsoka atsopano zinachitika mu July 2012, ku Krymsk. Akatswiri akadali odziwa zimayambitsa, koma anthu kupitiriza kufunafuna achibale awo akusowa.

Iwo likukhalira kuti zaka 25 zapitazi damu "Sindinaonepo" kukonzanso. Pankhani ya yoweyula kuti lapita pafupifupi hafu miliyoni ngozi. zaka zisanu ndi chimodzi zapitazo, damu anali ziyambe kukonzedwa. M'madera ena kusiyana anafika masentimita 50. Sergei Shoigu, nduna ya ZAKU Emergency ku Russia, anafotokoza zinthu ngati zovuta. Am'deralo komanso ankakonda analidziwitsa kumabungwe oyenera ngozi. Nduna Pomaliza, chibwenzi cha 2010. chaka loopsa kwambiri anatsimikizira. Koma si kuwomba kwa bingu ...

Ndipo anapha. Usiku wa pa June 7 yoweyula yaikulu kuphimba anthu kugona Krymsk, Novorossiysk, Gelendzhik. chiwerengero cha akufa anayesedwa kutali. Chiwerengerochi Official kuyika nambala ya anthu 200, ndiponso anthuwo kuti akuvutika kwambiri pa nthawi ...

Ziribe kanthu momwe owawa, koma apulumutse kumira akanali ntchito ya kumira. Komanso ngati anthu nthawi kumawadziwitsa kuyandikira vuto. Ndipo ngati ndi ayi? Kodi kuchita ngati chigumula abwera zonse mwadzidzidzi?

Tengani malo okwera (mtengo, ntsoyi ya nyumba). Mpokolowekapo gulu limene mudzatha kupeza. Usiku, kuoneka bwino kokha kuwala chizindikiro. Ngati madzi ali kale pa pakhomo, musazengereze kumanga improvised raft. Ngati inu nokha mu madzi, akathyole floaters lalikulu. Kodi si mantha. Pitirizani kupempha thandizo ndi maso. Chenjerani ndi mawaya amagetsi ndi zidutswa lakuthwa wa zinyalala. Osamwa madzi popanda processing. Kodi kudya chakudya otsekeredwa mu madzi.

Pambuyo pa mavuto a madzi, m'nyumbamo, Tsegulani zitseko zanu ndi mazenera zosatseka. Mpweya ndi magetsi magetsi pokhapokha mpweya wokwanira ndi chidaliro chonse zipangizo zabwino ndi wirings.
