Chiyambi
Kuyenda kwa njira yotsegukaKuyeza ndikofunikira kwambiri m'magawo monga kasamalidwe ka madzi m'mizinda, ulimi, ndi kukonza madzi otayidwa m'mafakitale. Kusankha mita yolondola yoyezera kuchuluka kwa madzi m'madzi kumakhudza mwachindunji ubwino wa deta komanso magwiridwe antchito. Mita yodziwika bwino yoyezera kuchuluka kwa madzi m'madzi imapereka maubwino apadera omwe amawasiyanitsa ndi njira zina zoyezera kuchuluka kwa madzi m'madzi, ndipo nkhaniyi ikufotokoza zabwino zake zazikulu.Zida za Lanry zapanga mitundu iwiri yamita yoyendera njira yotseguka.Amenewa ndi UOC ndi UOL.
1. Kugwira Ntchito Kwapamwamba Kwambiri Kwaukadaulo: Kulondola ndi Kukhazikika
Flumemita yoyendera njira yotsegukaYapangidwa ndi mfundo zotsimikizika za hydraulic ndi ma formula omwe adatsimikiziridwa kale, zomwe zimachepetsa kusonkhana kwa sediment kuti zikhale zolondola kwambiri. Mosiyana ndi zimenezi, mita yotsegulira njira yolowera m'madzi imavutika ndi masensa otsekeka ndi sediment, ma doppler models amavutika ndi kuchuluka kwa tinthu tating'onoting'ono, ndipo mita yoyendera liwiro la dera imakhudzidwa ndi kugwedezeka kwa madzi. Ma mita okhazikika amafunikanso kukonzedwanso pang'ono kuposa njira zina zosalowerera. Chogulitsachi chimagwiritsidwa ntchito pa njira zosiyanasiyana zoyendera, monga Parshall flume, Rectangular weir ndi Triangle weir.
2. Kusinthasintha Kwambiri pa Zochitika Zosiyanasiyana
Zopangidwa ndi zipangizo zosagwira dzimbiri, mita yokhazikika imagwira ntchito bwino pothirira madzi a m'nyanja ndi ulimi. Zosankha zina zimakhala zoipa kwambiri: masensa olowa m'madzi otayira madzi m'madzi a m'nyanja, ma transducer a doppler amatsekeka m'madzi a m'nyanja. Mita yokhazikika imayikanso njira za kukula konse—kuyambira m'ngalande zothirira mpaka m'machubu a madzi a m'nyanja—popanda kumangidwanso kwakukulu, mosiyana ndi liwiro la malo (limafunika kulinganizidwa bwino) kapena mita zina zosasokoneza.
3. Kugwiritsa Ntchito Ndalama Moyenera: Kuchepetsa Ndalama Zokonzera ndi Kuyika
Popanda zida zosuntha, mita yokhazikika imagwira ntchito kwa chaka chimodzi mpaka ziwiri popanda kukonza. Njira zina zimawononga ndalama zambiri: cholowa m'madzi chimafunika kutsukidwa pafupipafupi, kuwerengera doppler pamwezi, komanso kuyang'aniridwa kosasokoneza nthawi ndi nthawi—kuwonjezera ndalama zokonzera ndi 30-50%. Kukhazikitsa ndikotsika mtengo: ntchito yosavuta ya boma (monga kuyika zingwe zothirira ulimi, kuyika maziko a zimbudzi) kumachepetsa nthawi/ndalama ndi 50%, poyerekeza ndi liwiro la dera kapena mita yamadzi yamkuntho yosakhala yachizolowezi. Kuti mudziwe zambiri za momwe mungayikitsire mita, chonde omasuka kuwona zithunzi zomwe zili pansipa.
Mapeto
Masiku ano, makampani ambiri apanga zoyezera madzi zotseguka bwino, makamaka ma flume—ochita bwino kwambiri kuposa liwiro la dera, ma doppler, mitundu yosalowerera, komanso yolowa m'madzi, komanso njira zina zogwiritsira ntchito monga ulimi wothirira kapena njira zina zotsukira madzi, molondola, kusinthasintha, komanso kugwiritsa ntchito bwino ndalama. Ndi abwino kwambiri m'magawo a ulimi, m'matauni, komanso m'madzi amvula omwe amafunika kuyeza kodalirika komanso kotsika mtengo.
