hydrographic radar level gauge, eo hape e tsejoang e le "non-contact radar water level meter", ke sesebelisoa se tsoetseng pele se sebelisang maqhubu a motlakase a phahameng a maqhubu (li-microwave) ho metha sebaka sa sebaka sa metsi. E fetisa leqhubu la radar ka antenna 'me e amohela echo e hlahang holim'a metsi. Boemo ba metsi bo baloa ho latela nako eo leqhubu le e nkang sebaka sena.
Litšobotsi tsa eona tsa mantlha ke tse latelang:
1. Tekanyo eo e seng ea Khokahano
- Melemo: Sensor ha e ikopanye le 'mele oa metsi o lekantsoeng, ha e le hantle e qoba mathata a amanang le mekhoa ea ho ikopanya - joalo ka sedimentation ea silt, mofoka, corrosion le icing-tse otlang litekanyo tsa setso (mohlala, mofuta oa float, khatello e thehiloeng ho khatello).
- Sephetho: Tlhokomelo e tlase haholo le bophelo bo bolelele ba ts'ebeletso, e etsa hore e tšoanelehe haholo bakeng sa tikoloho e thata ea metsi.
2. Tekanyo e Nepahetseng e Phahameng, e sa Angoeng ke Maemo a Tikoloho
- Molemo: Ho ata ha maqhubu a radar ho hang ha ho angoe ke mocheso, mongobo, khatello ea sepakapaka, moea, pula kapa lerōle.
- Ha ho bapisoa le Ultrasonic Gauges: Ho nepahala ha tekanyo ea tekanyo ea Ultrasonic ho angoa ke ho fetoha ha mocheso o teng (ho hloka matšeliso) le moea o matla, athe maqhubu a radar a sebetsa hantle haholo maemong ana, a fana ka botsitso bo phahameng.
3. Matla a Matla a ho Thibela Tšitiso
- Melemo: Li-gauge tsa boemo ba radar hangata li sebetsa ho sehlopha sa K-band kapa maqhubu a holimo, a nang le sekhutlo se senyenyane sa mahlaseli le matla a kopaneng. Sena se li nolofalletsa ho phunyeletsa ka katleho foam, mouoane, le litšila tse nyenyane tse phaphametseng, 'me ha li amehe ke liphetoho tsa' mala oa metsi kapa ho teteana ha metsi.
- Sephetho: Litekanyo tse tsitsitseng le tse tšepahalang li ka fumanoa le holim'a metsi a nang le maqhubu a fokolang, foam kapa mouoane.
4. Ho Eketsoa ha Bonolo, Ha ho Tlhokeho ea Liphetoho tsa Sebopeho
- Molemo: E hloka feela sebaka se loketseng sa ho fanyeha ka holim'a ntlha ea tekanyo (mohlala, borokhong, sefapano se selibeng se khutsitseng, kapa palo). Ha ho hlokahale ho aha seliba se khutsitseng kapa ho etsa liphetoho tse kholo meahong e teng.
- Sephetho: E fokotsa haholo litšenyehelo tsa boenjiniere ba sechaba le ho rarahana ha ho kenya, haholo-holo ho molemo bakeng sa ho ntlafatsa liteishene tse teng.
5. Mefuta e mengata e fapaneng ea likopo
- Molemo: E ka sebelisoa hoo e batlang e le mefuta eohle ea mehloli ea metsi, ho akarelletsa le linōka, likanale, matamo, matša, liliba tsa metsi a ka tlas’a lefatše, le litanka tse fapa-fapaneng libakeng tsa ho hloekisa metsi a litšila (liliba tse kenang, litanka tse kenyang moea, joalo-joalo).
Mathata le Mehopolo:
- Litšenyehelo tse Phahameng tsa Pele: Litsenyehelo tsa ho reka hangata li phahame ha li bapisoa le li-transducers tsa khale tse ka tlas'a metsi kapa li-gauge tsa boemo ba metsi ba mofuta oa float.
- Tšitiso ea Bohata ba Echo: Lilibeng tse moqotetsane kapa tikolohong e rarahaneng e nang le liphaephe kapa li-brackets tse ngata, maqhubu a radar a ka bonts'a mabota a kahare kapa litšitiso tse ling, 'me a baka melumo ea bohata e hlokang ho sefa software. Li-gauge tsa sejoale-joale tsa radar hangata li na le li-algorithms tse tsoetseng pele tsa ho sebetsana le sena.
- Extreme Wave Impact: Metsing a bulehileng a nang le maqhubu a maholo haholo (mohlala, mabopo a leoatle, matamo a maholo), ho feto-fetoha ho matla ha holim'a metsi ho ka phephetsa botsitso ba tekanyo, ho hlokang hore ho khethoe mohlala o loketseng haholoanyane le sebaka se ntlafalitsoeng sa ho kenya.
2. Linyeoe tsa Kopo
Ka lebaka la tlhaho ea bona ea ho se kopane le ho ts'epahala ho hoholo, litekanyo tsa boemo ba radar li sebelisoa haholo ho lekola hydrometric, merero ea paballo ea metsi, le taolong ea metsi a litoropong.
Taba ea 1: Litsi tsa Tlhokomelo ea Hydrological in Mountainous Rivers
- Phephetso: Maemo a metsi linōkeng tse lithaba a phahama le ho theoha ka potlako, ka maqhubu a potlakileng a nkang litšila tse ngata le lithōle tse phaphametseng (makala, lehola). Li-sensor tsa setso li senyeha habonolo, li koalehile, kapa li ts'oareha, tse lebisang tahlehelong ea data.
- Tharollo: Kenya sekala sa boemo ba radar borokhong, 'me mochini o lebisitsoe ho ea holimo holim'a nōka.
- Sephetho:
- Ha e na Tlhokomelo: E qoba ka botlalo litlamorao tsa seretse le maloanlahla, ka ho ts'oara hydrograph e felletseng nakong ea likhohola.
- Polokeho: Basebeletsi ba ho kenya le ho lokisa ha ho hlokahale hore ba sebetse haufi le metsi a kotsi kapa nakong ea likhohola, ho netefatsa tšireletso.
- Botšepehi ba Lintlha: E fana ka lintlha tse tsoelang pele, tse nepahetseng tsa tlhokomeliso ea likhohola le taolo ea mehloli ea metsi.
Taba ea 2: Marang-rang a Metsi a Metsi a Litoropo le Tlhokomelo ea ho phalla ha metsi
- Phephetso: Tikoloho ea ka hare ea likhoerekhoere tsa litoropo le li-box culverts e boima, ka litaba tse kang likhase tse senyang, sedimentation ea silt le tšenyo ea likokoanyana. Li-sensor tsa ho ikopanya li senyeha habonolo ebile ho thata ho li hlokomela.
- Tharollo: Kenya litekanyo tsa boemo ba radar tse nang le litekanyetso tse phahameng tsa tšireletso (tse ka 'nang tsa se ke tsa phatloha) ka hare ho likoahelo tsa mekoti kapa maballo a pota-potileng ho lekanya boemo ba metsi ka har'a seliba.
- Sephetho:
- E Thibela ho Corrosion: Tekanyo e sa amaneng le motho ha e angoe ke likhase tse senyang ka har'a seliba.
- Anti-Siltation: E thibela ho hloleha ha sensor ka lebaka la ho patoa ka lehlabathe.
- Tlhokomelo ea Nako ea 'Nete: Liphaephe tsa ho shebella li tlatsitsoe ka nako ea sebele, li fana ka ts'ehetso ea data bakeng sa ho romelloa ha metsi litoropong le temoso ea ho phalla ha metsi, ho kenya letsoho mererong ea "Smart Water" le "Sponge City".
Taba ea 3: Tlhokomelo ea Polokeho ea Letamo le Letamo
- Phephetso: Boemo ba metsi a matamo ke paramente ea ts'ebetso ea mantlha, e hlokang tekanyo e tšepahalang le e nepahetseng. Mekhoa ea setso e ka 'na ea angoa ke ho hōla ha limela letsoapong la letamo ka har'a sebaka se feto-fetohang.
- Tharollo: Kenya litekanyo tsa boemo ba radar tse nepahetseng haholo mahlakoreng ka bobeli a tsela ea letamo kapa tora ea ho beha leihlo ho beha leihlo boemo ba letamo ka nako ea nnete.
- Sephetho:
- Ho Tšepahala ho Phahameng: E fana ka lintlha tsa bohlokoa ka ho fetesisa bakeng sa ts'ebetso ea taolo ea likhohola le phepelo ea metsi.
- Khokahano e sa Feleng: Lintlha li ka kopanngoa ka kotloloho lits'ebetsong tsa tlaleho ea ho na ha pula le lits'ebetso tsa ho lekola polokeho ea matamo, e nolofalletsang taolo e ikemetseng.
- Botsitso ba Nako e Telele: E batla e sa tabohe, e fana ka datha e ts'oanang ka nako e telele, e loketseng tlhahlobo ea polokeho.
Taba ea 4: Tekanyo ea Metsi a Iketselitsoeng Likanaleng tsa Nosetso
- Bothata: Likanale tsa nosetso tsa temo li na le phallo e bonolo empa li ka ba le mofoka. Hoa hlokahala mokhoa oa ho metha oa tlhokomelo e tlase bakeng sa taolo e nepahetseng ea mehloli ea metsi le tefiso.
- Tharollo: Kenya litekanyo tsa boemo ba radar likarolong tsa bohlokoa (mohlala, liheiti, li-flumes). Ka ho lekanya boemo ba metsi le ho bo kopanya le karolo ea marang-rang ea mocha le mohlala oa hydraulic, sekhahla sa phallo ea hang-hang le molumo o ntseng o eketseha o baloa.
- Sephetho:
- Kenyelletso e Nolofalitsoeng: Ha ho na tlhoko ea ho aha meaho e rarahaneng ea ho lekanya ka kanaleng.
- Ho Bala Methara e Hole: Ha e kopantsoe le liteishene tsa telemetry, e nolofalletsa pokello ea data ea othomathike e hole le tefo, e ntlafatsa taolo ea nosetso.
