Yintoni na isebe komlambo? Icacisa incazelo, iimpawu

Uviko - umsinga wamanzi, emlonyeni apho kumi enkulu, kumjelo ebalulekileyo, ichibi okanye elinye iqumrhu amanzi. KwiJografi kukho into efana kwemijelo engundoqo. Nguye kwaye enze nokungena amanzi. Makhe sihlolisise kwinkcazelo, khangela iindlela zokuhlela kunye neempawu yale yinxalenye emlanjeni.

Enye uviko ibizwa ngokuba indleko zamanzi, nto leyo komfula echibini, ichibi okanye enye ndawo.

Le ekungeneni lomlambo; inkcazelo emfutshane

Ngoko ke, ukusuka ngasentla kulandela ukuba flow kukongeza emlanjeni omkhulu. Yohluka ukususela kumsinga engundoqo zolwelo ngokuyintloko amanzi. Yokufika eli nani lingaphantsi kakhulu kunalowo umlambo apho ayajika. Kukwakho nezinye umahluko criteria. Le lobushushu emanzini, isalathiso wayo umbala, turbidity (ingcaciso) kunye nokwakheka imithi. Ngokumalunga uhlobo ukuhamba kwamanzi, oko anokwahluka. Umzekelo, yokufika - umsinga kwentaba, kwaye ijelo ephambili aqukuqela yeArabha, kunye ugeleza ngokuthe ngcembe. Ukusuka oku kuvela sigqibo mnye: isakhiwo elunxwemeni inokuba nomahluko kakhulu. Kakade ke, ubude. Eli nani kwi ukuhamba kwamanzi ephambili isoloko mkhulu kuba uye nemingenela.

Kufuneka kukhunjulwe ukuba umlambo zonke nemingenela yawo kuthiwa inkqubo umlambo lowo. Inani kwemali zibe Imijelo inokuba nomahluko ngokupheleleyo. Maxa wambi kuba nzima ukufumanisa apho umlambo engundoqo kunye nemingenela yawo apho. Kuyenzeka ukuba ubukhulu yokugqibela ibe nkulu kakhulu ngaphezu kwemijelo engundoqo.

Apho ekuqaleni yokufika

Imvelaphi ekungeneni umlambo kuthatha kwimithombo, imigxobhozo, iintaba, ezihambayo. umthombo wayo ithathwa indawo apho track eziphathekayo iqala a flow izinzile. Uviko - umlambo apho ujikeleza umlambo rhoqo yamanzi yendalo. Yiyo ehamba channel laphela ukususela ekuqaleni umthombo ukusa emlonyeni. Ukuze nemingenela ukumisela kwithambeka usisizalwane ngengingqi, njengoko umthetho, oko phantsi ngokupheleleyo.

nemingenela yokuhlela

Yinxalenye yenkqubo umlambo nto yokufika. Oku kuquka njenge emlanjeni omkhulu, kunye nemisinga emathunjini omhlaba. Kukho ikho into ekunene nemingenela ekhohlo. Ukusuka igama kucaca ukuba ukuhamba lokuqala olungundoqo kwicala ekunene kwicala flow, kwaye eyesibini, ngokulandelelana, ukusuka ekhohlo.

Kwisebe iphambili umlambo wabukela umyalelo 1. Ezi imilambo iqukuqela igalele ngqo kwi kuyo. Kodwa zibizwa - imijelo eziphambili lomlambo. Ngako kwemali ukuze flow 2 kungena omlambo i-odolo 1, njalo njalo. D. Ngenxa kule yokuhlela kwinkqubo umlambo kwaye imilambo emikhulu kunye nemisinga.

Kwiplanethi enguMhlaba, kukho imilambo ukuba omlambo malunga 20 imiyalelo zobukhulu. Kwakhona, kukho omnye Ukuhlelwa: ukuqala kuncinci ukuya ku- nkulu.

iimpawu nemingenela

ekungeneni nganye, kwakunye emlanjeni omkhulu, uye iimpawu zayo kunye neempawu:

• ubukhulu indawo yamanzi;
• indawo amanzi emvula,
• amanzi abalekayo emvula ngonyaka;
• lexinene kothungelwano lomlambo;
• kuwa phantsi nento ithambeka lomlambo.

Kwimephu ye Ukraine, umzekelo, kukho malunga nama-71 amawaka. Rivers. Eyona mithombo yamanzi iphambili ingeniso kwiingingqi ezininzi kuhlala kwebanga engundoqo kunye ekungeneni lomlambo lowo ujikeleze lonke kwindawo ethile, ngokuba leyo, yaye wenza ebalulekileyo. imilambo anjalo yinxalenye ebalulekileyo yokusingqongileyo inkqubo basic, umthombo wamanzi okusela kunye namanzi mveliso.
