Waa maxay riverbed ah? geeddi socodka Channel iyo waxbarashada

Waa maxay riverbed? Taas oo qayb ka (qeybaha) waxay u qaybsan yahay? Maxaa togaga loo sameeyay gudahood riverbed ah?

Mid kasta oo inaga mid ah wuu og yahay waxa ay u egtahay webiga oo ay sariirta. Waxaa laga yaabaa in cidhiidhi ah ama ballaaran, gacmeed ama qoto dheer, si joogto ah ama ku meel gaar ah. Waa maxay jihada ka barta of view of science? Jawaabta su'aashan waxaa laga heli karaa boggayaga article.

Waa maxay caadiga ah: qeexida iyo nuxurka of fikradda

- il biyo webi waa asal ahaan dabiiciga ah, kuna waari dhexdeeda size a weyn. Oo dunida oo dhan la jira channel webi. Waa maxay?

Ka hadal waxa a hydrologists qasac riverbed. Waa saynisyahano kuwa sahaminta kala duwan qaababka biyo. Ma webiyaasha oo keliya, laakiin harooyinka, dhoobada, berkadood, iwm Laakiin keliya webiyada waa waxa aynu doonayno inaynu u fiirsan in warqad this si faahfaahsan. Sidaas daraaddeed, waa maxay jihada?

Riverbed yeedhay chute in ay dusha dhulka on Kan webigu ku soo aqueous socodka ah. Tani waa shayga ugu hoos dooxada webiga. Waa in la ogaadaa dhibic muhiim ah: channel, isagoo ku saleysan iyo "aasaas" ee webiga, waxaa la sameeyay.

Channel waxaa laga yaabaa in aad u kala duwan ka soo kasta oo kale oo muuqaalka iyo size. Webiyada waaweyn (sida Volga Dnepr ama Amazon) ay width gaadho dhowr kiilomitir. Isla mar ahaantaana channel ee durdurraa ka yar iyo webiyada qofka waa ay awoodaan in ay si fudud ku boodaan. In ka channel Wabiyaal dooxada, inta badan hubka qalloocan oo badan, buuraha iyo - a dheeraad ah si toos ah iyo si xoogan qaabkii dhagaxyo, dhagxaanka, dogob geed.

Sidaas daraaddeed, waxaan fahamsanahay in channel noocan oo kale ah. Hadda waxaan u ogaato sida badala dhul ku wareegsan.

geeddi socodka Channel iyo qaababka ay

Si aad si fiican u fahmaan arrinta in uu yahay jihada waa in aad aqoon u leh geedi socodka in ay dhacaan waxa ku jira.

Under channel geedi socodka lug gabi ahaanna ee geedi socodka iyo dhacdooyinka ugu dambeyntii keeni isbeddel ku dhimaya qaabka iyo riverbeds. Waayo, markii ugu horeysay ee ay ku hawlan cilmi xataa qarniyadii dhexe. Sayidka, saynisyahan caan Talyaani Galileo Galilei shaqeeyeen mashruuca, toosinta ah ee qallooca ee Tiber ah si loo yareeyo heerarka daadka, kuwaas oo sannad walba ay daadadku Rome. geeddi socodka Maanta channel barataa anshaxa gaar ah oo cilmi ah - River fataahadda.

The salaysan hawlgaladaa waa dhexgalka biyaha dal oo dusha ka dahsoon. Webiga jebiyo dhagaxyada, iyaga qaada si ay meel fog ka mid ah iyo dib u dhacyada (ururayaa) in meel cusub. Sidaas darteed of hawlgaladaa, mutates dooxada Webi laftiisa iyo qabanayaa noocyo cusub.

hydrologists Riverbed sida caadiga ah loo qaybiyaa saddex qaybood (qeybta):

• durdur sare (halkan heysatay geedi socodka burbur);
• macnaheedu socodka;
• Dabcan hoose (halkan habka raasamaal dega halaagnay ee dhulka ee River wax sare).

Man ayaa bartay in ay si weyn u bedeli sariirta webiga. -qabashada aadanaha Active ka badali karo qaab (tusaale ahaan, rectifying durdurro biyo ah), iyo xataa jihada of qoto dheer. All this, dabcan, ma dafiri karto in ay saamayn ku dynamics of hababka channel dabiiciga ah.

Ruslovye Waxbarashada: gudbi jiray, Ples, Rapids iyo waterfalls

Sidaas darteed of riverbed shaqo farsamo sameeyay tiro ka mid ah dhismayaasha gaar ah iyo togaga:

• tog;
• sastrugi;
• ples;
• rogo;
• marinkii;
• Falls iyo kuwa kale.

Brod - waa meel-gacmeed on sariirta webiga, kaas oo webiga loo gudbay kartaa lug ah ama by gaariga. In qarniyadii dhexe, in laga gudbo weyn oo inta badan lahaa magaalada oo dhan. Maanta, wax badan oo ka mid ah magacyada meel la xidhiidha erayga: tusaale ahaan, magaalada Brody ee Ukraine, Havlickuv Brod in Czech Republic, Oxford ee UK (tog in turjumaad ka soo English - "tog").

Sastrugi yeedhay ciid ama ciid-dhagax dixeed elongated streamer amro in biyaha. Ples - qayb ka qoto dheer sariirta webiga, taas oo loo sameeyay bangiga concave ee Meander ah.

Sariirta webiyo iyo durdurro buurta waxaa badanaa adag oo ay Rapids, Rapids iyo waterfalls. Iyo marinnadii albaabbada loo sameeyay meelaha dusha sare ee wejiga waa dhagaxyada aad u xoog badan in webiga ma iska maydh karaa iyo baabbi'in. Falls - a formation geomorphological gaar ah, qarka dhagax ee webiga, taas oo biyaha uu hoos u dhaco si xor ah hoos.

Bifurcation sariirta webiga

Bifurcation webiga - an arrin dabiici ah oo xiiso leh iyo halkii ay dhif. Erayadani waxay ka imanayaan bifurcus hadalkii Latin, taas oo macnaheedu yahay "forked". Bifurcation - channel kala (oo ay ku jiraan dooxada Webi) on laba socodka biyaha madax banaan. In mustaqbalka, qulqulka waa kuwan mar dambe ku xiran iyo qulquli gelin berkadood kala duwan. Inta badan this ifafaale ayaa lagu arkay webiyaasha bannaankii, kaas oo ay maamulaan on guri, barbareeyay dusha dhulka ee.

Tusaale ahaan ugu caansan adduunka ee channel bifurcation - waa Orinoco River ee South America. In qeybaha sare ee wabigga ee laamaha iyada hubeeyo Casiquiare. In mustaqbalka, waa ku xiga si ay nidaamka webiga Amazon ah, isaga oo ku saabsan mid ka mid saddexaad ee faniinkaba guud ee Orinoco ah.

Gebogebadii ...

Waa maxay riverbed ah? Qeexidda fikrad this iyo baadhitaan faahfaahsan - mid ka mid ah hawlaha sayniska ee biyaha raaca. Sariirta - taasi waa mid ka mid ah xubno ka ugu weyn ee dooxada webiga, chute dabiiciga ah taas oo socodka aqueous si toos ah guuro.

sariirta webiga waxaa si joogto ah jebinta geedi socodka dhacaan, barakaca iyo aruursaday wax dhulka. Sidaas darteed, hawlgaladaa loo sameeyay gargaarka microforms gaar ah: gudbi jiray, sastrugi, Ples, shoals, Rapids iyo waterfalls.
