—Kuwongolera Kusefukira kwa Madzi ndi Kuyang'anira Zinthu Zamadzi mu Mekong Delta
Chiyambi
Mekong Delta ku Vietnam ndi dera lofunika kwambiri pa ulimi komanso lokhala ndi anthu ambiri ku Southeast Asia. Komabe, m'zaka zaposachedwapa, kusintha kwa nyengo kwawonjezera mavuto monga kusefukira kwa madzi, chilala, ndi kulowa kwa madzi amchere. Machitidwe oyendetsera madzi achikhalidwe amakumana ndi kuchedwa kwa deta, ndalama zambiri zokonzera, komanso kufunika kwa masensa osiyana a magawo osiyanasiyana.
Mu 2023, Vietnam Institute of Water Resources (VIWR), mogwirizana ndi Ho Chi Minh City University of Technology ndi thandizo laukadaulo kuchokera ku GIZ (German Agency for International Cooperation), adayesa masensa amadzimadzi a m'badwo wotsatira okhala ndi radar m'zigawo za Tien Giang ndi Kien Giang. Masensawa amathandiza kuyang'anira nthawi yomweyo kuchuluka kwa madzi, liwiro la madzi, ndi mvula, kupereka deta yofunika kwambiri yowongolera kusefukira kwa madzi ndi kuteteza zachilengedwe m'dera la delta.
Ubwino Waukulu Waukadaulo
- Kuphatikiza Atatu-mu-Chimodzi
- Imagwiritsa ntchito mafunde a radar a 24GHz okwera pafupipafupi poyesa liwiro lochokera ku Doppler (±0.03m/s molondola) ndi microwave reflection kuti madzi akhale okwanira (±1mm molondola), kuphatikiza ndi choyezera mvula chozungulira.
- Kompyuta yolumikizidwa mkati imakonza zolakwika zomwe zimachitika chifukwa cha dothi kapena zinyalala zoyandama.
- Mphamvu Yochepa & Kutumiza Opanda Waya
- Yoyendetsedwa ndi dzuwa yokhala ndi LoRaWAN IoT yolumikizira, yoyenera madera akutali opanda gridi (kuchedwa kwa data
- Yoyendetsedwa ndi dzuwa yokhala ndi LoRaWAN IoT yolumikizira, yoyenera madera akutali opanda gridi (kuchedwa kwa data
- Kapangidwe Kosagonja ku Masoka
- IP68 yovomerezeka motsutsana ndi mphepo yamkuntho ndi dzimbiri la madzi amchere, yokhala ndi chimango chosinthika choyikira kuti chizitha kusinthasintha ndi kusefukira kwa madzi.
Zotsatira za Kukhazikitsa
1. Chenjezo Lothandiza Kuthetsa Chigumula Cha Madzi
Mu Chigawo cha Chau Thanh (Tien Giang), netiweki ya masensa inaneneratu kuti madzi otuluka m'mitsinje adzaphwanyidwa maola awiri pasadakhale panthawi ya kutsika kwa madzi m'malo otentha mu Seputembala 2023. Machenjezo odziyimira pawokha adayambitsa kusintha kwa zipata za m'mphepete mwa madzi, zomwe zidachepetsa madera omwe anasefukira ndi 15%.
2. Kusamalira Kulowa kwa Mchere
Mu Ha Tien (Kien Giang), kuchuluka kwa madzi amchere omwe amalowa m'madzi nthawi yachilimwe kunathandiza kuti madzi amchere aziyenda bwino, zomwe zinachepetsa kuchuluka kwa mchere m'madzi othirira ndi 40%.
3. Kusunga Ndalama
Poyerekeza ndi masensa a ultrasound, zipangizo zogwiritsa ntchito radar zinachotsa mavuto otsekeka, zomwe zinachepetsa ndalama zokonzera pachaka ndi 62%.
Mavuto ndi Maphunziro Omwe Taphunzira
- Kusintha kwa Zachilengedwe: Kusokonezeka koyamba kwa chizindikiro cha radar kuchokera ku mitengo ya mangrove ndi mbalame kunathetsedwa mwa kusintha kutalika kwa masensa ndikuyika zoletsa mbalame.
- Kuphatikiza Deta: Zida zapakati zakanthawi zinagwiritsidwa ntchito kuti zigwirizane ndi National Hydro-Meteorological Database (VNMHA) ya Vietnam mpaka kuphatikiza kwathunthu kwa API kumalizidwe.
Kukula kwa Mtsogolo
Unduna wa Zachilengedwe ndi Chilengedwe ku Vietnam (MONRE) ukukonzekera kuyika masensa 200 m'maboma 13 a delta pofika chaka cha 2025, ndi kuphatikiza kwa AI kuti adziwitse za ngozi yophwanya madamu. Banki Yapadziko Lonse yalemba ukadaulowu muNtchito Yolimbana ndi Nyengo ku Mekongzida zogwiritsira ntchito.
Mapeto
Nkhaniyi ikuwonetsa momwe masensa anzeru ogwiritsira ntchito madzi amathandizira kuwongolera masoka amadzi m'madera otentha a mvula, zomwe zimapereka yankho lotsika mtengo komanso lodalirika kwa mayiko osauka.
