1. Mita rere awa tuwhera UOL mō ngā momo paipa me ngā pā wai
Ka taea te ine tika i tēnei mita mā te taumata o ngā wai. Ina whakamahia hei ine i te rere o te wai mō te awa tuwhera, me tāuta he paipa wai me he pā wai.Ka taea e te pā wai te huri i te rere ki te taumata wai i roto i te awaawa tuwhera. Ka ine te mita i te taumata wai i roto i te awaawa pā wai, kātahi ka tatau i te tere rere i runga i te whanaungatanga wai-rere o te awaawa pā wai e rite ana i roto i te tukatuka iti i roto i te mita. Ko ngā awaawa pā wai matua ko ngā awaawa Bacher, te pā tapatoru me te pā tapawhā. I te ine i te taumata wai, ka whakamahia te hangarau whakaata ultrasonic, ā, ka whakanohoia te ine taumata ki runga ake i te pūwāhi tirotiro taumata wai o te pā wai. Ka whakaritea poutū te papa tuku o te ine taumata ki te mata wai. I raro i te mana o te rorohiko iti, ka tukuna, ka whiwhi hoki te mita taumata ultrasonic i ngā ngaru ultrasonic. E ai ki te Hb=CT/2 (ko C te tere oro o te ngaru ultrasonic i te rangi, ko T te wā o te ngaru ultrasonic i te rangi), ka tatauhia te tawhiti Hb i waenga i te mita taumata ultrasonic me te taumata wai i inehia, kia whiwhi ai i te teitei taumata wai Ha. Hei whakamutunga, ka whiwhihia te rere wai i runga i te tātai tatau rere. Nā te ine kore-pā, ka taea te whakamahi i roto i ngā taiao uaua. He pai te mita rere o te awa tuwhera mō ngā puna wai, ngā awa, ngā kaupapa tiaki wai, ngā awa whakawhiti i te tuku wai o te tāone, ngā awa whakawhiti i te whakamatao o ngā tipu hiko wera, te maimoatanga paru ki roto me ngā awa tuku, ngā tikanga mahi o ngā kaupapa tuku wai para o te umanga me ngā kaupapa tiaki wai, me ngā awa whakamakuku ahuwhenua.
2. Mita rere tere tuwhera o te awaawa raupapa DOF6000 mō te awaawa, te paipa kua kī katoa rānei
Ka whakauruhia e te mita rere tere rohe te ine i te tere rere me te ine taumata wai, ka whakamahia te mātāpono Doppler ultrasonic mō te ine i te tere rere.I te ine i te taumata wai, ka whakanohoia te pūoko ki raro, ki te taha rānei o te rohe wai. Mā te pūoko pēhanga waipū, ka whai mahi te taura tohu hiko hei whakapūngao. Ka whakamahia te pēhanga hau i runga i te mata o te wai hei pēhanga tohutoro mō te pūoko pēhanga waipū hei ine i te pēhanga wai, kia taea ai te tatau i te teitei o te taumata wai. He pai te mita rere ultrasonic tere-rohe mō te ine i roto i ngā awa tuwhera, i ngā paipa kāore i te kī, he nui ake i te 300mm te whānui mō te tuku i te wai para me te wai para, ngā awa ma, te wai inu me te wai moana.
