He nui ngā rauemi hiko wai i ngā rohe maunga nā te nui o te ua, te pari o te whenua, me ngā rerekētanga teitei. Nā ēnei painga taiao he wāhi pai mō te whakawhanake i te hiko wai. Heoi, me āta whakamahere me te hangarau te hanga i tētahi tipu hiko wai i ngā rohe maunga kia pai ai te whai hua, te haumaru, me te pumau o te taiao. He maha ngā mahi matua o te whakamahere tika, mai i te aromatawai rauemi ki te whiriwhiri taputapu me te whakahaere taiao.
1. Whakahaerehia te Rangahau Wai
Ko te taahiraa tuatahi ki te whakamahere i tētahi tipu hiko wai maunga ko te ako i ngā rauemi wai o te rohe. Me tātari e ngā miihini ngā raraunga wai mō te wā roa, tae atu ki te rere o te awa, ngā rerekētanga o ngā wā, ngā taumata waipuke, me ngā āhuatanga o te tauraki. I ngā rohe maunga, ka rerekē te rere o te wai i waenga i ngā wā ua me ngā wā maroke.
Mā te kohikohi me te tātari i ngā raraunga wai, ka taea e ngā kaiwhakamahere te whakatau i te rere o te hoahoa, te kaha kua tāutahia, me te whakatau tata o te whakaputanga hiko ā-tau o te tipu hiko. Ko ēnei mōhiohio te tūāpapa mō ngā hoahoa hangarau katoa e whai ake nei.
2. Kōwhiria he Pae Tika
Ko te whiriwhiri i te wāhi tētahi o ngā mea tino nui mō te whakawhanaketanga o te hiko wai. I ngā whenua maunga, ka rapua e ngā kaiwhakamahere ngā wāhi he nui te hekenga o te teitei taiao (te pane wai) me ngā āhuatanga whenua pumau.
Ko te pae tino pai me whai:
Te rere o te wai e tika ana puta noa i te tau
He nui te rerekētanga teitei hei whakaputa hiko whai hua
Ngā hanganga toka pumau mō te hanganga haumaru
He urunga watea mō te kawe i ngā taputapu me ngā hanganga
Ka taea e te wāhi kua whiriwhiria pai te whakaiti i ngā utu hanga me te whakapai ake i te pono o te tipu hiko wai mō te wā roa.
3. Whakatauhia te Kaupapa Whakawhanake
I muri i te whiriwhiri i te wāhi, me whakatau e ngā kaihangarau te kaupapa whakawhanake hiko wai tino pai. I ngā rohe maunga, ko ngā kaupapa tino noa ko:
Ngā pūnaha rere-o-te-awa – Ka whakamahia e ēnei tipu te rere tūturu o te awa me te iti, te kore rānei o te wai e penapenahia ana. He iti noa te pānga ki te taiao, ā, e whakamahia whānuitia ana mō ngā kaupapa hiko wai iti me te rahi.
Ngā tipu hiko wai momo-whakarerekē – Ka hurihia te wai mai i te awa mā roto i tētahi awaawa, i tētahi kauhanga rānei ki tētahi whare hiko kei tētahi teitei iti iho. Ka whakamahia katoatia e tēnei hoahoa te rerekētanga o te pūtake tūturu o ngā wāhi maunga.
Ngā tipu momo puna wai – Ka rongoa e ēnei tipu te wai i muri i te tāpae, kia pai ake ai te whakahaere i te rere me te pumau ake o te whakaputa hiko.
I roto i ēnei kōwhiringa, he tino pai ngā pūnaha momo tahuritanga mō ngā wāhi maunga nā te mea ka taea e rātou te whakatutuki i te tino whai huatanga me te kore e hiahiatia he tākai nui.
4. Kōwhiria ngā taputapu turbine e tika ana
He mea nui te whiriwhiri i te tāpine tika kia eke ki te whai huatanga me te mahi pono. Ko te momo tāpine e whakawhirinaki ana ki te kaha e wātea ana me te rere o te wai.
E whakamahia whānuitia ana ngā tāpine Pelton i ngā kaupapa hiko wai maunga teitei te pane me ngā tere rere iti.
He pai ngā tāpine Francis mō ngā āhuatanga rere-waenga me ngā āhuatanga rere-waenga.
Ko ngā tāpine Kaplan, ngā tāpine ngongo rānei, e whakamahia ana mō ngā wāhi iti te pane.
Mā te whiriwhiri tika i ngā tāpine ka whakarite kia tino whai hua te hurihanga pūngao me te mahi pumau mō te wā roa.
5. Hoahoahia ngā Hanganga Hiko Wai Matua
He maha ngā wāhanga nui o tētahi pūnaha hiko wai maunga:
Hanganga whakauru
Poihau tango paru, puna taunga rānei
Pūnaha kawe wai (awaawa, paipa, kauhanga rānei)
Tāke Forebay, tāke pupū rānei
Penstock
Whare hiko me te pūnaha whakaputa hiko
Te hongere Tailrace
Me āta hoahoa ia wāhanga kia pai ai te rere o te wai, kia whakaitihia ai te ngaronga o te pūngao, kia mau tonu ai te haumaru o te mahi.
6. Whakamaherehia te Hanganga me te Waka
He maha ngā wero mō ngā mahi whakarite i ngā wāhi maunga. Me hanga pea ngā rori, ngā piriti, me ngā whare hanga rangitahi i mua i te tīmatanga o ngā hanganga nui. Me kawe haumaru ngā taputapu taumaha pēnei i ngā tāpine, ngā whakaputa hiko, me ngā whakawhiti hiko ki ngā wāhi mahi tawhiti.
Mā te whakamahere hanga whai hua ka taea te whakaiti i ngā whakaroa o te kaupapa me te whakahaere i ngā utu whānui.
7. Whakaarohia te Tiaki Taiao
He wāhanga nui te tiaki taiao i roto i te whanaketanga hiko wai o ēnei rā. Me aromatawai ngā kaiwhakamahere i ngā pānga pea o te kaupapa ki ngā rauropi me ngā hapori o te rohe.
Ko ngā mahi matua mō te taiao ka uru atu ki:
Te pupuri i te rere o te taiao i roto i te awa
Te tiaki i ngā mea ora i roto i te wai me ngā ara hekenga ika
Te whakahaere i te whakatōtō me te horo
Te whakaiti i te kino o ngā tipu i te wā hangahanga
Mā te whakauru i ngā whakaaro taiao ki roto i te tukanga hoahoa, ka taea e ngā kaupapa hiko wai te whakatutuki i te whanaketanga tauwhiro.
Ko te whakamahere i tētahi tipu hiko wai i ngā rohe maunga me whai huarahi whānui e whakakotahi ana i te tātari wai, te hoahoa hangarau, te whiriwhiri taputapu, me te tiaki taiao. Ina whakamaheretia me te whakatinanahia tika, ka taea e ngā kaupapa hiko wai maunga te whakarato i te pūngao pono ka taea te whakahou, te tautoko i te whanaketanga ōhanga ā-rohe, me te whai wāhi ki ngā mahi ā-ao ki te whakaiti i ngā tukunga waro.
