Reka na Vikimedijinoj ostavi

Gang ili Ganga je jedna od najdužih reka Indijskog potkontinenta. Reka izvire u zapadnom delu Himalaja u indijskoj saveznoj državi Utarančal, teče severnim delom Indije, prelazi u Bangladeš, i uliva se u Bengalski zaliv kao delta u području Sundarbans. Gang je treća reka u svetu po količini vode na ušću.

U hinduizmu, Gang se smatra svetom rekom.^[1] Ova reka je takođe izvor života za milione Indijaca koji žive duž njenog toka i zavise o nje za svoje svakodnevne potrebe.^[2] Ona se obožava kao boginja „Gang“ u Hinduizmu.^[3] Ona je isto tako bila istorijski važna, sa mnoštvom bivših pokrajinskim ili imperijalnim prestonicama (kao što su^[4] Kanauž, Kampilja, ^[4] Kara, Alahabad, Kaši, Patna, Hažipur, Munger, Bagalpur, Muršidabad, Baharampur, Nabadvip, Saptagram, Kolkata i Daka) lociranim na njenim obalama.

Gang je rangiran kao peta najzagađenija reka na svetu 2007. Zagađenje ugrožava ne samo ljude, nego i više od 140 ribljih vrsta, 90 amfibijskih vrsta i ugroženu vrstu indijskog rečnog delfina.^[5] Nivoi fekalnih koliformi od ljudskog otpada u vodama reke u blizini Varanasija su više od sto puta veći od zvaničnog limita Indijske vlade.^[5] Akcioni plan Ganga, je jedna od inicijativa za zaštitu životne sredine usmerena na čišćenje reke, koja do sad nije bila uspešna,^[6] usled korupcije, nedostatka tehničke stručnosti, lošeg planiranja životnog okruženja, i nedostatka podrške lokalnih verskih vlasti.

Geografske karakteristike

Gang se oblikuje spajanjem pet malih reka na južnim obroncima Himalaja; Bagirati, Alaknanda, Mandakini, Dauliganga i Pindar, u indijskoj državi Utarahand.^[7]^[8] Dva najveće su Alaknanda i Bagirati, Alaknanda izvire 50 km severno od himalajskog vrha Nanda Devi, a Bagirati izvire na 3000 m nadmorske visine, ispod lednika Gangotri kog Hindusi smatraju svetim.^[9] Za izvor Ganga se smatra mesto Gaumuk koje leži 21 km jugoistočno od Gangotrija, gde se spajaju Alaknanda i Bagirati, tek odatle se reka zove Gang.

Gang od obronaka Himalaja teče gotovo pravolinijski u smeru jugoistoka prema Bengalskom zalivu. Porečje Ganga pokriva četvrtinu Indije, dela koji je najgušće naseljen u kom živi stotine miliona ljudi. U njemu su se rađale i umirale istorijske civilizacije kao što je Maurijsko carstvo (322. p. n. e.) sve do Mogulskog carstva iz 16. veka.^[9] Gang protiče kroz indijsku državu Utar Pradeš gde prima svoju najveću desnu pritoku Jamuna kod Alahabada, tu dobija i tri velike leve pritoke; Ramgangu, Gomti i Gagaru.^[9]

Karta sliva Ganga i Bramaputre

Nakon tog reka teče kroz državu Bihar gde prima pritoke sa Himalaje; Gandaki, Buri Gandak, Gugri i Koši i najvažniju južnu pritoku Son. Nakon tog reka teče kroz poslednju indijsku državu Zapadni Bengal, gde prima zadnju indijsku pritoku Mahanandu.^[9]

U svom donjem delu, reka teče kroz Bangladeš, tu se spaja sa Bramaputrom i skreće na jug. Zajednička reka se odatle zove Padma, koja kod glavnog grada Bangladeša Dake dobija veliku pritoku Megnu (odatle se reka zove Megna) i počinje formirati najveću deltu na svetu - Delta Ganga, kojom se uliva u Indijski okean preko Bengalskog zaliva.^[9]

Deo delte uz more, sa najvećom šumom mangrove na svetu poznatom kao Sundarbans i Indija i Bangladeš proglasili su Nacionalnim parkom, koji je UNESKO uvrstio u Svetsku baštinu, i to 1987. indijski deo, a 1997. i deo koji pripada Bangladešu.^[9]

Geologija

Indijski potkontinent leži na Indijskoj tektonskoj ploči, manjoj ploči unutar Indo-australijske ploče.^[10] Njeni definicioni geološki procesi počeli su pre sedamdeset i pet miliona godina, kada je, kao deo južnog potkontinenta Gondvana, započeo severoistočno pomeranje - tokom pedeset miliona godina - preko tada neformiranog Indijskog okeana.^[10] Naknadna kolizija potkontinenta sa Evroazijskom pločom i subdukcija ispod nje, proizveli su izdizanje Himalaja, najvišeg planinskog lanca na planeti.^[10] U bivšem morskom dnu neposredno južno od Himalaja, kretanje ploča je kreiralo ogromno korito, koje, nakon što je postepeno napunjeno sedimentima koje je nosile reke Ind i Gang sa njigovim pritokama,^[11] sad formira Indo-ganšku niziju.^[12]

Indo-ganška nizija je geološki poznata kao pregibna ivica ili pregibni sliv.^[13]
