River Delta - isimo semvelo ekhethekile

Iningi labantu kuyinto, uyini-delta lomfula, kodwa hhayi wonke, cabanga indima ukuthi udlala ezimpilweni zonke izinhlobo yezimila nezilwane ezihlukahlukene. Yini Lalimeleleni? Kumiswa nge inhlabathi ka Emathafeni emfuleni elise sifinyelela yayo ephansi - River Delta. Ngokuvamile it is kakhulu zingene inethiwekhi Amapayipi futhi hoses. Lokhu elisezansi wadala isimo semvelo ekhethekile. Delta uthola igama layo kusukela omunye izinhlamvu zamagama ngesiGreki, okuyinto njengoba injalo asivumelani ngokuqinile okusikhumbuza delta lasendulo esingunxantathu iNayile.

Ngo inqubo ukuxhumana eside phakathi emfuleni ukugeleza, ulwandle noma iziphazamiso wasolwandle, umoya-yokwanda kwama imisinga, amagagasi, futhi inzika umthwalo emfuleni ngamunye yakha delta esiyingqayizivele, okungase kuthathe eziyikhulu namashumi ngaphezulu ayizinkulungwane amakhilomitha square. Ngo iGanges kuthatha cishe izinkulungwane 106 sq. M. km, kuyilapho Amazon - ayizinkulungwane 100 amakhilomitha square.

Delta ungaqala amakhulu amakhilomitha emlonyeni wayo. Delta ukubeka phambili ezinye imifula kolwandle noma ulwandle, kuyilapho abanye - cha. Ngaphansi kwethonya olwandle imifula emikhulu njenge-Amazon, lase-Amur, the OB, taz, lePhure kukhona Delta, asikho ngaphezu ugu abahlala bomdabu.

Lapho amanzi omfula lunesibalo kakhulu iyunifomu kusukela olwandle, i-delta eqala umumo tapered (isib Neil). Uma amanzi emfuleni amumethe imvula, kuba luthe ukuqina kuka kolwandle, kanjalo ngaphansi kwethonya delta yayo ezidinga ukuma side. Ngezinye ukuminyana ongaphakeme amanzi emfuleni deltas akhiwa ngenombolo enkulu amapayipi amanzi Amapayipi (p. Mississippi).

Iningi imifula emhlabeni abe delta nge anesihlabathi athuthukile (anesihlabathi) imisebenzi. Lawa iVolga, uLena Terek, Severnaya Dvina, Kuban futhi iNeva. emifuleni Abaningi eningizimu iba "ngokushelela" nezimila ocebile futhi izilwane zasendle ezihlukahlukene. Ziyakwazi zokudoba abalulekile. Izitshalo zinokuphila okunempilo emelelwa amakhambi ahlukahlukene, nemihlanga bulrush, kwezihlahla notshani. Bathanda axazulule izinyoni nezinhlobo ezihlukahlukene zezilwane.

ukubaluleka Akuve inhlabathi okuzala futhi umswakama ise delta emfuleni. Emazweni amaningi emhlabeni kubo sikhule ingxenye enkulu izitshalo yezolimo. utshani Juicy ku izimfunda olumanzi, elise sifinyelela engezansi emifuleni, kukhona i-RSS feed kakhulu ngemfuyo. Isigodi iGanges iNayile, eMfuleni Yellow, iDanube kukhona ezindaweni ezolimo zazivuma.

Peculiar iyona delta iNeva River, ogeleza udlule ezindaweni ezisezansi izimbuku iNeva flat. Lomfula kunemibandela ihlukaniswe yaba izingxenye ezimbili (imodi uhlamvu): phezulu (umthombo - Ivanovskie imibundu), 30 km, kanye ngezansi (Ivanovskie imibundu - emlonyeni), 44 km ubude. Esikhathini esezansi (mayelana 15 km kusuka umlomo) yakha delta ububanzi iNeva eziphithizelayo Amapayipi iziqhingi emide kanye neziteshi. Yasungulwa ngenxa yokwanda kwama futhi ebbs lamanzi olwandle futhi ngaphansi kwethonya egeleza amanzi. Esikhathini delta iNeva yisona siqhingi esikhulu kunazo Krestovsky, Vasilevsky, Petrograd, le Decembrists. imikhono yakhe kukhona Small futhi Big iNeva Small, Medium and iNeva elikhulu.
