Estuary

Mumwe rukova runoyerera kubva kupi, apo yakatangwa, uye kuwana simba, ndokuguma kurwizi muromo, mainozonodira mumwe muviri mvura (ocean, gungwa, nyanza, rwizi kana zvimwe mvura Dam). Zvinoreva kuti pamuromo rwizi - ndiwo paaibatana yayo nezvimwe miviri mvura. Vamwe havana muromo zvachose, dzimwe nguva havana nahwo ari doro, saka arambe kuguma yorwizi haisi nguva dzose zvinoita.

Pane pfungwa anonzi bofu muromo. Zvinogona kutaridzika nokuda aome kana apo mvura seeps muvhu, jecha, kana rwizi runoyerera kupinda namahwindo mudhamu.

Netsika kusiyanisa mhando izvi nemumiromo, sezvinoita Delta uye estuary:

• River Delta sediments chikwereti chacho chitarisiko rikukurwe uye kubviswa zvigadzirwa zvavo akawanda;

• Estuary - zvikazara rezasi chikamu mumupata.

Kana gungwa kudzika rwizi mumuromo, haisi yakaratidzwa naTidhari masaisai uye rwizi uye anoita zvikuru zvakawanda deposits, tinogona zvakachengeteka kutaura kuti hunhu akasika ose ezvinhu kuti chidzoke yacho Delta.

Muenzaniso pakukura Delta munyika ndiwo muromo Amazon. It ndokwenguva nzvimbo dzinopfuura zana chiuru mativi makiromita. Just ari Delta atambanudza mumwe shasha - Marajó, chihombe rwizi chitsuwa zvinopfuura munharaunda Scotland. Amazon River stuns muromo wake, yava Vakapfuura upamhi Chirungu Channel kagumi. Saka hazvishamisi kuti yokunaya rwizi kutanga kubuda dzarwo uye pakudaro chokusatongofashamidzazve yakapoteredza dondo. Zviri akafuma kwazvo hove, uye uswa. Kune mamwe marudzi kuti zvinowanika chete Amazon. Nokuda upamhi muchinjikwa hazvisi nyore zvakadaro, zvichaita kutora mana maawa kuita kudaro.

Estuaries vari akaumba apo achideredza pachiwi pane muromo rwizi. Kudeuka estuary Anozvirumbidza rwizi Ob. Inonzi Ob muromo, kureba vanenge 800 km, 50-70? Km pahupamhi nokudzika 25 m.

Nzizi dzinoyerera munzvimbo inotonhora kweArctic mumakungwa, marudzi akasiyana mumiromo yavo. Somuenzaniso, Lena River, uye vamwe, tiri kumabvazuva, ndivo Delta. Ivo akazivisa uende kure mugungwa. Avo vari kumavirira fomu estuaries.

Muromo Dniester River, iyo inoyerera muGungwa Dema, kunoratidzwa nokuumbwa yakadai estuary. Uye wake muvakidzani Danube akaumba panguva pamuromo Delta. Zvii vakabatsira ichi, vachiri zvisinganzwisiswi masayendisiti, chiedza akakwanisa kukanda chete aoma.

A nyore chimiro Delta Delta ane muromo. Inoitwa mhotsi dzangu mbiri, izvo riri kumativi maviri chiteshi. Izvi mhando zvinogona chete kuonekwa pamusoro penzizi diki Somuenzaniso, muna Italy - p. Tiber. mhotsi dzangu kwakadaro akazviratidza apo kuerera mwero murwizi rava duku, asi padandemutande kuti akachengetedzwa.

Uyewo haana kwose mhando chipande anoonekwa kuti Delta. Muenzaniso uyu chinogona kuoneka pakati Mississippi River. Delta izvozvo kwamuka nokuda furcation mugero, umo nyaya kuva namatavi akawanda. Prerequisites zvinogona zvakasiyana: kubva akaoma, kupedza simba womunhu chinhu.

kwemarudzi aya deltas inoumbwa ne confluence yegungwa. Pane imwe mhando, iyo inozivikanwa nokuva inoyerera munzvimbo shoma bays. Delta kwakadaro kunyange vane zita - kuuraya. Muenzaniso - Danube River. kunakidza kwazvo Niger Delta nokuti pamupendero wayo akatedza gandiwa. A yakawanda nesimba kuisa ichi gungwa egungwa.
