Ko tētahi o ngā whenua ine ahurei ko ngā awa tuwhera, arā, ko te rere o ngā wai i te mata kore utu ka "tuwhera" ki te āhuarangi i ētahi wā. He uaua pea ēnei ki te ine, engari mā te aro nui ki te teitei o te rere me te tūnga o te awa ka āwhina i te whakanui ake i te tika me te manatoko.
I te ao o te ine wai whai hua me te tika, he maha ngā taputapu hei whiriwhiri. I runga i te āhuatanga, te rere o te wai me te wāhi e hiahiatia ana te ine wai, tera pea he otinga ine wai whai hua. Heoi, ko tētahi o ngā whenua ine ahurei ko ngā awaawa tuwhera – tae atu ki ngā awaawa whakamakuku, ngā awaawa, ngā tukanga wai, me ngā rerenga o ngā pūnaha parakaingaki me ngā pūnaha wai ua – kei reira te rere o ngā wai i te mata kore utu ka "tuwhera" ki te āhuarangi i ētahi wā.
He uaua pea te ine i te rere o te wai i roto i tētahi awa tuwhera. Kāore ngā awa tuwhera e pēhangahia ana, nō reira, kāore e taea te whakamahi i ngā waeine ine paipa katoa pērā i te Venturi, te mita rere hikohiko, te mita rere wā whakawhiti rānei. Ko tētahi huarahi noa ki te ine i te rere i roto i tētahi awa tuwhera ko te ine i te teitei, te "upoko" rānei o te wai i a ia e whiti ana i tētahi here (pēnei i tētahi awaawa, i tētahi pā wai rānei) i roto i te awa. Mō tētahi awa tuwhera e rere noa ana i roto i tētahi waeine ine tuatahi kua whakahaeretia, ka taea e te teitei o te rere (upoko) te tohu tika mō te rōrahi rere, ā, nō reira ka taea te ine tika i te tere rere.
Kātahi ka taea e te mita rere taumata wai radar Doppler i whakawhanakehia e mātou te whakatutuki i te ine tika.
Whakamutunga
Kei te piki haere te hiranga o te ine tika i te rere o ngā awa tuwhera. Ka pā kino te pikinga whānui, te whakatōtō, te hurihanga nui rānei o te āhua ki te tika me te pono o te awa Parshall tuku iho, ā, he maha tonu ngā wā ka pā kino. Nā te iti haere o te wai awa e wātea ana, me te hiranga hoki o te ine me te whakahaere i te rere o te wai para me ētahi atu rere wai awa tuwhera, me whai whakaaro ki te tika hei whiriwhiri i tētahi otinga whai hua. Hei whakatutuki i ngā hua pono, ka taea te whai, me titiro ki tua atu i ngā tuku tuku iho ki te whakatupuranga e whai ake nei o ngā otinga ine rere ka taea te whai.
