Icala Lokusebenza Kwezinzwa Ze-Hydrological Ze-Radar Ezisekelwe Kumapharamitha Amathathu E-Vietnam

—Ukulawulwa Kwezikhukhula Okusha kanye Nokuphathwa Kwemithombo Yamanzi eMekong Delta

Ingemuva

I-Mekong Delta yaseVietnam iyisifunda esibalulekile kwezolimo futhi esinabantu abaningi eNingizimu-mpumalanga ye-Asia. Kodwa-ke, eminyakeni yamuva nje, ukuguquka kwesimo sezulu kuye kwandisa izinselele ezifana nezikhukhula, isomiso, kanye nokungena kwamanzi anosawoti. Izinhlelo zokuqapha amanzi zendabuko zihlushwa ukubambezeleka kwedatha, izindleko eziphezulu zokulungisa, kanye nesidingo sezinzwa ezihlukene zamapharamitha ahlukene.

Ngo-2023, i-Vietnam Institute of Water Resources (VIWR), ngokubambisana ne-Ho Chi Minh City University of Technology kanye nokusekelwa kobuchwepheshe okuvela ku-GIZ (i-German Agency for International Cooperation), yahlola izinzwa zamanzi ezisebenzisa i-radar ezisekelwe ku-triple-parameter ezifundazweni zaseTien Giang naseKien Giang ngesizukulwane esilandelayo. Lezi zinzwa zivumela ukuqapha ngesikhathi sangempela izinga lamanzi, ijubane lokugeleza, kanye nemvula ngesikhathi esisodwa, zinikeza idatha ebalulekile yokulawula izikhukhula kanye nokuvikelwa kwemvelo endaweni yase-delta.

Izinzuzo Eziyinhloko Zobuchwepheshe

1. Ukuhlanganiswa Kwabathathu Koyedwa
   • Isebenzisa amagagasi e-radar aphezulu angu-24GHz ukuze kulinganiswe ijubane elisekelwe ku-Doppler (ukunemba okungu-±0.03m/s) kanye nokubonakaliswa kwe-microwave ukuze kutholakale izinga lamanzi (ukunemba okungu-±1mm), kuhlanganiswe nesilinganiso semvula esilingana nebhakede.
   • Ikhompyutha eyakhelwe ngaphakathi ilungisa amaphutha abangelwa ukungcola noma ukungcola okuntantayo.
2. Ukudluliselwa Kwamandla Aphansi Nokungenantambo
   • Isebenzisa amandla elanga ngokuxhumeka kwe-LoRaWAN IoT, ifanele izindawo ezikude ezingaphandle kwegridi (ukubambezeleka kwedatha
3. Umklamo Omelana Nezinhlekelele
   • Isilinganiso se-IP68 ngokumelene neziphepho kanye nokugqwala kwamanzi anosawoti, kanye nohlaka lokufaka olulungisekayo ukuze luvumelane nezikhukhula.

Imiphumela Yokusetshenziswa

1. Isexwayiso Esithuthukisiwe Sezikhukhula Kusenesikhathi
ESifundeni saseChau Thanh (eTien Giang), inethiwekhi yezinzwa yabikezela ukwephulwa kwezinga lamanzi emifudlaneni amahora ama-2 kusengaphambili ngesikhathi sokwehla kwesimo sezulu esishisayo ngoSepthemba 2023. Izexwayiso ezizenzakalelayo zabangela ukulungiswa kwesango lokungena kwamanzi elingaphezulu komfula, kunciphisa izindawo ezikhungethwe yizikhukhula ngo-15%.

2. Ukuphathwa Kokungena Kosawoti
E-Ha Tien (eKien Giang), idatha yesivinini sokugeleza okungajwayelekile ngesikhathi sokungena kwamanzi anosawoti esizini eyomile isize ekwenzeni ngcono ukusebenza kwesango lolwandle, yanciphisa usawoti wamanzi okunisela ngo-40%.

3. Ukonga Izindleko
Uma kuqhathaniswa nezinzwa ze-ultrasonic, amadivayisi asekelwe ku-radar asuse izinkinga zokuvaleka, anciphisa izindleko zokulungisa zonyaka ngo-62%.

Izinselele Nezifundo Ezifundiwe

• Ukuzivumelanisa Nemvelo: Ukuphazamiseka kokuqala kwesignali ye-radar okuvela kuma-mangrove nezinyoni kwaxazululwa ngokulungisa ukuphakama kwenzwa nokufaka izinto zokuvimbela izinyoni.
• Ukuhlanganiswa Kwedatha: I-middleware yesikhashana yasetshenziswa ukuze ihambisane ne-National Hydro-Meteorological Database (VNMHA) yaseVietnam kuze kube yilapho ukuhlanganiswa kwe-API okugcwele kuqediwe.

Ukwanda Kwesikhathi Esizayo

UMnyango Wezinsiza Zemvelo Nezemvelo waseVietnam (i-MONRE) uhlela ukufaka izinzwa ezingama-200 kuzo zonke izifundazwe eziyi-13 zase-delta ngo-2025, ngokuhlanganiswa kwe-AI ukuze kubikezelwe ingozi yokuphulwa kwamadamu. IBhange Lomhlaba lifake ubuchwepheshe ohlwini lwayoIphrojekthi Yokumelana Nesimo Sezulu saseMekongithuluzi lamathuluzi.

Isiphetho

Leli cala libonisa indlela izinzwa ezihlakaniphile zamanzi ezihlanganisiwe ezithuthukisa ngayo ukuphathwa kwezinhlekelele zamanzi ezindaweni zasezindaweni ezishisayo, okunikeza ikhambi elingabizi kakhulu nelithembekile emazweni asathuthuka.

Isethi ephelele yamaseva kanye ne-software engenantambo module, isekela i-RS485 GPRS /4g/WIFI/LORA/LORAWAN
