Ko te hiko wai te tūāpapa o te pūngao hou o te ao, e whakarato ana i te hiko ma, pono, me te utu-pai. Heoi, ko tōna pono e hono pūmau ana ki tētahi taurangi kotahi, e kore e taurite: te rere o te wai. He mea nui te mārama ki te pānga o te rerekētanga o te rere hei whakapai ake i te whakaputa hiko, hei whakarite i te pumau o te whatunga hiko, me te whakamahere mō tētahi heke mai e ātete ana ki te āhuarangi.
Te Whārite Taketake: Mana, Upoko, me te Rere
I tōna pūtake, ko te putanga hiko o tētahi tipu hiko wai e whakahaerehia ana e tētahi tauira māmā:
P = η * ρ * g * Q * H
Kei hea:
P = Putanga Mana
η = Te Whai Huatanga Whānui
ρ = Te Matotoru o te Wai
g = Te Whakaterenga Ā-papa
Q = Te Rere o te Rere (te rahinga o te wai ia hekona)
H = Upoko (te teitei o te wai e taka ana)
Mai i tēnei whārite, e mārama ana ko te Tere Rere (Q) he kaiārahi tika, rārangi hoki o te whakaputa hiko. He pānga tere, he pānga ōrite hoki tō tetahi panonitanga o te rahinga wai e tae atu ana ki ngā tāpine ki te hiko e whakaputaina ana.
Te Wero Takirua o te Rerenga Rere
1. Te Raru o te Rere Iti
Ina heke te rere o te wai i raro iho i te kaha hoahoa o tētahi tipu, ka ara ake ētahi wero nui:
Te Whakaiti i te Putanga Hiko me te Ngaronga Moni Whiwhi: Koinei te pānga tino tika. Ko te iti o te rere he iti ake te wai hei hurihuri i ngā tāpine, ka heke te whakaputa hiko, ā, ka ngaro hoki ngā moni a te kaiwhakahaere.
Te Kore Mahi: Kua hangaia ia tāpine mō tētahi "pūwāhi pai rawa atu" i tētahi tere rere motuhake. Mā te whakahaere i ngā rerenga iti rawa ka panaia te tāpine ki waho o tēnei awhe pai rawa atu, ka whakaiti i tōna pai, ā, ka piki ake pea te pakaru me te haehae nā te cavitation (te hanganga me te hinga o ngā mirumiru hau, ka kino pea ngā mata o te tāpine).
Ngā Wero o te Whakapau Pūmau o ngā Wāhanga: I roto i ngā tipu hiko maha-wāhanga, ka ārai pea te rere iti i tētahi, neke atu rānei o ngā wāhanga whakaputa hiko. Ko te whakatau ko ēhea ngā wāhanga hei whakahaere me te kaha ka noho hei raruraru arotau uaua.
Ngā Here Taiao me ngā Here Ture: I ngā wā tauraki, he maha ngā wā ka whakahaua e ngā ture taiao te tuku i te "rerenga iti rawa" hei pupuri i te hauora o te rauropi o raro. Ka whakaitihia anō hoki te wai e wātea ana mō te whakaputa hiko, ka hanga he taurite ngāwari i waenga i te whakaputa pūngao me te tiaki taiao.
2. Te Raru o te Rere Nui
Ahakoa te āhua nei he pai ake te nui o te wai, he maha ngā raruraru o te nui rawa o ngā rerenga:
Te maringi me te maumau pūngao: Ina nui ake te kaha o te rerenga mai ki te puna wai, i te kaha tukunga mōrahi rānei o ngā tāpine, me "ringi" e ngā kaiwhakahaere te wai taikaha ki runga i te tāmi. He maumau tika tēnei o te pūngao pea kua taea te huri hei hiko.
Ngā Herenga Hoahoa o te Tāpine: He tere rere mōrahi tō ia tāpine ka taea e ia te whakahaere haumaru. Mēnā ka nui ake i tēnei herenga, ka pāngia te pūkaha me te wiri, ka kino hoki te kaiārahi me ētahi atu wāhanga.
Ngā Take Whakatakotoranga: He nui te paru me te paru e puta mai ana i ngā rerenga wai nui. Ka taea e tēnei te pakaru o ngā wāhanga o raro i te wai, ka ārai hoki i ngā arai whakauru, ā, me utu nui te tiaki me te horoi.
Te Whakarerekē ki tētahi Rerenga Rerekē
He maha ngā rautaki e whakamahia ana e te umanga hiko wai hei whakaiti i ngā pānga o te rerekētanga o te rere o te wai:
Ngā Puna Wai me ngā Pā: Ko te otinga matua ko te rokiroki. He rite ngā puna wai ki te pākahiko, e hopu ana i ngā rerenga wai nui i ngā wā ua, e tuku ana hoki i te wai kua rongoatia hei whakaputa i ngā wā maroke. Mā tēnei ka whakangawari i te rerekētanga taiao, ā, ka whakarite kia pono ake te pūtake hiko.
Hangarau Tāpine Matatau: Mā te whanaketanga o ngā tāpine mata-whakarerekē, pērā i a Kaplan (mō te pane-iti) me Francis (mō te pane-waenga-teitei), ka taea te pupuri i te whai huatanga i runga i te whānuitanga o ngā rerenga. E mōhiotia ana hoki ngā tāpine tāpine tāpine (e ai ki tāu pātai o mua) mō tō rātou whai huatanga pai i raro i ngā āhuatanga rere rerekē.
Tātari Matapae me te Matapae: Mā te whakamahi i ngā raraunga huarere me ngā tauira wai, ka taea e ngā kaiwhakahaere te matapae i ngā rerenga mai me te tika haere. Mā tēnei ka taea te whakahaere pai ake i ngā puna wai, te whakatau i te wā e penapena ai i te wai me te wā e whakaputa nui ai hei matapae i ngā huihuinga rere nui, iti rānei a meake nei.
Ngā Pūnaha Whakaheke: Ka taea te whakahaere tahi i tētahi raupapa o ngā tipu hiko wai i runga i te awa kotahi. Ko te tukunga wai kua whakaritea mai i tētahi tipu whakarunga ka huri hei rerenga mai mō te tipu whakarunga, ka whakaiti i ngā rerekētanga nui o te rere mō te pūnaha katoa.
Te Take Huringa Āhuarangi
Kei te whakanui ake te huringa āhuarangi i te wero o te rerekētanga o te rere. He maha ngā rohe e pāngia ana e ngā āhuatanga wai tino kaha me te auau: te tauraki roa me ngā ua nui ake. Nā tēnei ka kore e tino pono ngā raraunga rere o mua, i hangaia ai te nuinga o ngā tāhuna. Nō reira, me whakauru e te whakamahere hiko wai hou te manawanui ki te āhuarangi, te hoahoa me te whakahaere i ngā tipu mō tētahi heke mai me te koretake o te wai.
Whakamutunga
Ehara te rerekētanga o te rere i te take taha engari he mea nui o te whakaputa hiko wai. Mai i te ahupūngao taketake o te whakaputa hiko ki ngā whakataunga uaua mō te whakahaere me te taiao, ko te nui o te wai e rere ana i roto i te tipu te mea e whakatau ana i tana mahi, i tōna ōhanga, me tōna pumau. Mā te whakamahi i te hangarau atamai, te matapae matatau, me te hoahoa ngāwari, ka taea e te rāngai hiko wai te haere tonu ki te whakatere i ēnei rerekētanga, me te pupuri i tana tūranga nui i roto i te whatunga hiko ma, pumau hoki.
