Nutrition kunye emlanjeni ulawulo

Mode kuthetha ulawulo-odolo. Eli gama lisetyenziswa ukuchaza ukuba umyalelo kwiindawo ezininzi zezinto ezenziwa luluntu, kwakunye nohlobo ezingqongileyo. Omnye umzekelo woku ulawulo lomlambo. Kodwa ukuba abantu kubomi bemihla ngemihla ibambelela ngendlela ethile, e-emlanjeni, ngokufuthi uthatha indawo abaziisuphavayiza - uthi intlokoma ibakho emlanjeni yobomi, kwaye kuphela kwezinye iimeko, kusengaphazamisana nolawulo kwamanzi ukuyitshintsha.

Nawuphi na umba ihlabathi kungachazwa ngokumnika impendulo. Kuquka iimpawu anikwe kunye namaqumrhu yamanzi aphezu komhlaba - iilwandle, iilwandle, amachibi, imilambo, nemigxobhozo. Olubizwa le abalinganiswa of nemin. Oku ngokuyimfuneko iquka ulawulo ezinamanzi umlambo - iseti iimpawu ezizodwa kuzakuthsintsha imeko emlanjeni kwexesha.

Nemin uncuma Iboniswa oscillations diurnal, ngamaxesha athile kunye ingaphelelwayo kwamanzi kunye nesiqulatho amanzi (ndawonye imo amanzi), ice izenzakalo, ubushushu bamanzi, ubungakanani mba kumiswe emanzini stream hydrochemistry, utshintsho ukhuko umlambo, lo Velocity flow, ukuphazamiseka kunye nezinye izenzakalo kunye neenkqubo ezenzeka ngokuqubekayo kwindlela emlanjeni yobomi. Zonke ezi zinto kunye nezinye olawulo ezinamanzi kwi aggregate ukuqinisekisa ulawulo lomlambo.

Kuxhomekeka ukuba okanye hayi apho yamanzi emlanjeni, ekwaziyo ukuphembelela kwi ulawulo ezinamanzi umlambo zilawulwa phezu-imowudi okanye yendalo (ikhaya). Kuzo zonke izinto olawulo lomlambo libaluleke kakhulu ukuba uthini ukuqengqeleka. yobukhulu bawo umisela ummandla wamanzi cut, oovimba ezifunda lombane, zamanzi ubukhulu umyalezo kule ndawo.

River ulawulo kuxhomekeke kwizinto ezininzi: imozulu, uncedo ezisentlabathini, ubonelelo lwamanzi kunye nabanye. The main factor - amanzi amandla. Zokutya omlambo zivela komoya kwinkqubo umjikelo wamanzi endalweni. Amanzi ngokunikezela imilambo amandla uwahlule ube ngumkhenkce, ikhephu, imvula kunye komhlaba. La magama efanayo wabhenela ekumiseleni iintlobo zokutya nemilambo. Kwezinye iimeko kunzima ukuchaza ngokucacileyo nokubaluleka omnye umthombo wamandla , igama elithi 'uhlobo mixed lokutya "emlanjeni (uhlobo lwamandla umlambo) kwaye ke isetyenziswe.

Isigaba (periods) ulawulo zolwelo iimpawu uphawu zahlulwe imilambo yamanzi ephantsi eliphezulu lamanzi kunye. Flood enayo ngonyaka ngaxesha elithile lonyaka, kukho ukwenyuka elide kunye kumabanga aphakamileyo kunye umxholo amanzi lexikulu xa kuthelekiswa nezinye izigaba. amanzi Low naye ngamaxesha athile yaye lubonakala ngokuba kwinqanaba elisezantsi kunye nomxholo liphantsi amanzi; ngeli xesha lo mlambo wondla ikakhulu komhlaba. Zigcwala amanqanaba semvelo olukhawulezileyo kwaye zezomzuzwana phezulu umthamo omkhulu wamanzi; ukuba kwenzeka ngenxa yemvula, snowmelt.
Iimpawu loMlambo umNayile: Umlambo imilambo yawo kusekwe kwindlela umlambo Rukakara-Kager Nile yi 6852 km - oko umlambo wesibini elide emhlabeni. Nile aqukuqela ukusuka ezantsi kuse entla ukuya kuLwandle lweMeditera. flow ngokukhawuleza esemlanjeni yayo ephezulu nesiphakathi emazantsi kade-isindululo; ukuya emlonyeni loMnayile yahlulwe imikhono eziliqela kufutshane noLwandle lweMeditera yenza ogudle mkhulu. UNeil - umthombo wobomi kwiSahara entlango. Phantse bonke abemi baseYiputa (97%) bahlala ngaselunxwemeni yayo. kumjelo esisigxina Nile unikele ngonyaka-ngeenxa iimvula ethandwa (area kummandla Blue Nile) kunye nemvula kwiindawo esemazantsi (izehlo of the White Nile), kunye neemvula kwimimandla Abyssinian, iyadilika umhlaba evakalala. River flow uthwala kumiswa, nokunqanda intlenga okunezondlo kwi ogudle, emadlelweni apho amaYiputa kuvuna ukususa ukuya amaxesha 3 ngonyaka. Ukuze ulawulo konogumbe, apho inqanaba amanzi omlambo kummandla Cairo inyuke nge-8 m, owaboyikisa intlekele labemi, bakha Aswan Dam odumileyo. Kwaye ngoku uMlambo umNayile kwimimandla esezantsi umbuso kulawulwa. Kodwa ngoxa uNeil ixesha amaxesha iVolga 3 kwikhondo yalo uthwele umthamo wamanzi ngamaxesha 2 ezincinane.
