Ukuwa ithambeka lomlambo - yintoni na? Ukumisela kwamaxandeka imilambo: iVolga, Amur, Pechora

River - a amanzi imvelaphi yendalo, ujikeleze lonke kwijelo, kusebenze kakuhle. Kuyenzeka ukulinganisa ubude komfula, inani nemingenela yawo, indawo eqokelela amanzi emvula oqhelekileyo, njl Enye andaweni iparameters eziphambili - ithambeka lomlambo. Indlela ukubala ngayo?

Yintoni ukuhla emlanjeni?

Nasiphi na ogqobhozela zendalo kwi planethi aqukuqela ukusuka phezulu ukuya ezantsi. Isizathu soku - kakuhle makwazeke kuni nonke kuthi umthetho gravitation jikelele, leyo yavulwa Isaakom Nyutonom ngxi phakathi kwinkulungwane XVII. Yonke imilambo ngokwesiqhelo luzakuqala ukusuka kwimithombo komhlaba okanye zivela namachibi amakhulu. Emva koko bathwale ezantsi zabo amanzi (ngokucotha okanye ngokukhawuleza) - ukuya elwandle kunye neelwandle.

Fall River ibonisa ukuba bangaphi na olahlekelwa ngobude okanye ogqobhozela ebudeni "uhambo" yakhe kumphezulu womhlaba. Ngamanye amazwi, umahluko ukuphakama phakathi eyintsusa yako kunye ingongoma emlonyeni lomlambo. Fall inokuba epheleleyo okanye kwinxenye (xa kuyimfuneko ukubala le isalathisi umjelo kwicandelo elithile).

Bala umlambo drop-brainer. Ukuze wenze oku, kufuneka wazi ubude umthombo wayo emlonyeni. Umzekelo, sifumana umlambo kunye ubude abangama-2,000 km, eqala uhambo lwayo kwi-250 m, kwaye ingena edikeni kwintaba ephakame-50 m. Umahluko phakathi kwezi mpawu zimbini ziya kuba mitha 200. Oku kuya kuba ukuwa emlanjeni A.

Ukwazi kwehla kubalwa kunye ithambeka lomlambo. Indlela yokwenza oko - ufunde eli candelo lilandelayo.

Indlela yokubala kwithambeka kwamanzi?

Kwithambeka umlambo - lulwahlulo ukuwa ngasemfuleni kufuneka ubude bayo iyonke. Isalathisi ingavezwa ekhulwini mille (amaninzi) izidanga okanye m / km.

Nelamaxandeka nelezihlambo kunye nemilambo intaba ziyahluka kakhulu. Kwimeko yokuqala, eli nani kunqabile ukudlula 0.1 m / km. Kwamaxandeka imilambo kwentaba kuba kumashumi okanye amakhulu amaxesha ngaphezulu.

Bala kakhulu eli nani lula. Makhe sibuyele lomlambo wethu A, nto leyo ilingana ukuhla 200 meters. Ukubala ixabiso ithambeka kukuba kufuneka bahlulwe ixabiso ubude lomlambo: 200 m / 2,000 km = 0,1 m / km. Kule sinokuthi umlambo yethu A - tyaba kwaye ngesantya elisezantsi flow yayo.

Fall River, kwaye ithambeka angamelwa ngokwegrafu. Ukulungiselela le njongo, i-njalo kuxokwa-iimboniselo zabucala longitudinal. Axis "x" le shedyuli ziya kuba ubude lomlambo, kwaye axis "y" - ukuphakama ngengingqi. Le iprofayile ibukeka ngolu hlobo lulandelayo:

Ukuwa kwithambeka iVolga

Ukusombulula iingxaki ezinjalo ezifundiswa esikolweni, kuba izifundo geography kwibakala 8. Thabatha umzekelo wamanzi inkulu eYurophu - iVolga. Makhe zama ukubala ukuwa ithambeka lomlambo.

IVolga eliya kwicala yaseYurophu weRashiya, uluhlu lwezifundo 15 nakwiimanyano ezichaphazelekileyo. Wayesoloko otshintsha ndlela yayo. Le umzila ibalulekileyo lizwe, umlambo likhulu ehlabathini ezo imijelo yamanzi ukuba musa kuwela elwandle okanye olwandle.

IVolga asuka kwi Valdai Hills, kwintaba ephakame 228 iimitha ngaphezu komphakamo wolwandle. Ngaphakathi kummandla Astrakhan, ayajika kuLwandle lweCaspian. Ngelo xesha linye umlomo umi kwintaba ephakame (-28) mitha. Ngenxa yoko, i-drop iyonke iVolga - 256 leemitha. Ngoku ukubala ithambeka lomlambo.

IVolga linobude abangama-3530 km. Ngelo xesha nye eqokelela amanzi indawo enkulu million 1,36 square. M. km. Oku ngokuphindwe kane kunobelizwe kummandla Germany! Ukubala kwithambeka iVolga kufuneka ukwenza i operation ilandelayo zemathematika: 256 m / 3530 km = 0,07 m / km.

Ukuwa kwithambeka Amur River

Enye lwemilambo emikhulu waseMpuma Ekude, ophuma phakathi kwamazwe amabini (Russia neChina), - i cupid. umthombo wayo ithathwa ekudibaneni Shilka kunye Argun. Ukuphakama kwale ngongoma ngaphezu komphakamo wolwandle - 304 eemitha. Further Amur aqukuqela ikakhulu ukuya ngasempuma eliya Okhotsk. Ukuphakama umlomo wakhe 0 leemitha. Ngenxa yoko, abantu ngokubanzi drop Amur - 304 leemitha. Thina ukubala ithambeka lomlambo.

Cupid linobude abangama-2824 km. Ummandla isitya million 1,85 square metres. km. Ukubala kwithambeka Amur kufuneka enze operation yezibalo elula: 304 m / 2824 km = 0,11 m / km.

Esi salathisi isixelela ukuba thina kwi ubude site ijelo elinye ukusuka kwi Amur River "uyaphambana" iisentimitha 11 ukuphakama. Kubalulekile ukuqaphela ukuba kwithambeka jikelele kancinane zomlambo ulwazi. Eneneni, iimeko geomorphological (iimeko terrain), nto leyo ke umandlalo umlambo, zinokwahluka kakhulu. Ngoko ke kungcono ukuba ukubala esi salathisi for izigaba elifutshane somlambo.

Ukuwa kwithambeka Pechora River

Pechora - umlambo enkulu kangangoko Russian kamnandi ngaphakathi Komi kwiRiphabliki kunye Nenets District Ukuzilawula. Iqala ezintabeni Northern Urals Mountains, kwintaba ephakame 630 iimitha ngaphezu komphakamo wolwandle. Pechora kwemali endaweni Bay kwegama elifanayo kuLwandle Barents, kusekwe Delta enkulu. Ukuphakama emlonyeni - 0 eemitha. Thina ukubala ukuwa ithambeka lomlambo.

Pechora linobude abangama-1809 km. Ukuwa umlambo leemitha 630. Le ndawo ye Pechora River isitya kuthelekiswa ne iVolga kunye Amur lincinane - kuphela 330 amawaka macala M.. km. Ukubala kwithambeka Pechora River kufuneka ukwenza i operation zemathematika zilandelayo: 630 m / 1809 km = 0,35 m / km.

Njengoko sele sibonile, phakathi bathathu kuxutyushwa kweli nqaku, imilambo inkulu bias uphawu le Pechora. Ngokubanzi, inkcazelo zesi salathisi kunceda hydrologists ingakumbi ukufunda entilini lomlambo, umbuso wayo amanzi kunye neenkqubo channel.
