GLEN CANYON, ARIZONA - Raws li Western Tebchaws Meskas cuam tshuam nrog keeb kwm megadrought, txhua qhov dej poob yog qhov tseem ceeb. Nyob rau hauv ib kauj ruam tseem ceeb ntawm kev tswj dej kom meej, US Geological Survey (USGS), koom tes nrog cov dej hauv xeev, tau tshaj tawm txoj kev ua tiav ntawm kev ua tiav ntawm kev soj ntsuam xyuas dej-radar ntws los ntawm Glen Canyon Dam ntawm Colorado River. Qhov kev xa tawm no yog lub sijhawm tshiab ntawm lub sijhawm tiag tiag, kev sau cov ntaub ntawv muaj tseeb rau ib qho ntawm Asmeskas cov dej tseem ceeb tshaj plaws.
Qhov Kev Sib Tw: Kev ntsuas qhov tseeb hauv txoj kab tseem ceeb
Lub Colorado River yog "txoj sia," muab dej rau kev ua liaj ua teb thiab kaum lab tus tib neeg thoob plaws xya lub xeev Asmeskas thiab Mexico. Kev qhuav dej tsis tu ncua tau ua rau cov dej hauv nws cov dej ntws loj, Lake Powell thiab Lake Mead, poob qis. Kev ntsuas thiab tswj xyuas txhua qhov cubic meter ntawm cov dej tso tawm hauv qab tau dhau los ua qhov teeb meem tseem ceeb rau cheeb tsam kev lag luam thiab kev ruaj ntseg.
Cov dej ntws hauv qab Glen Canyon Dam yog tus cwj pwm los ntawm kev txav ceev thiab dej khov, ua rau kev sib cuag-raws li kev ntsuas kev ntsuas tsis yog txaus ntshai rau cov kws tshaj lij tab sis kuj nyuaj rau kev ua tiav thaum lub sijhawm huab cua huab cua. Qhov no yav dhau los ua rau muaj qhov sib txawv thiab qeeb ntawm cov ntaub ntawv thaum lub sijhawm tseem ceeb tshaj plaws.
Txoj kev daws teeb meem: Chaw taws teeb, txuas ntxiv, thiab siab-siab radar saib xyuas
Lub tshuab tshiab uas tsis muaj kev sib cuag radar flow meter (xws li tus qauv los ntawm SENIX lossis Valeport) yog ruaj khov rau ntawm tus choj nqes dej ntawm lub pas dej. Nws ua haujlwm los ntawm emitting radar nthwv dej ntawm tus dej ntws thiab tshuaj xyuas lub teeb pom kev zoo siv Doppler nyhuv los xam qhov nrawm nrawm yam tsis muaj kev sib cuag nrog dej.
"Cov kab ke no ua haujlwm zoo li 24/7 'hydrologic sentinel," piav qhia USGS tus kws tshaj lij. "Nws tshem tawm tag nrho cov kev pheej hmoo ntawm cov sensors raug puas tsuaj los ntawm dej nyab lossis cov khib nyiab. Qhov tseem ceeb tshaj plaws, thaum muaj xwm txheej dej nyab-thaum tus dej nyab xeeb tshaj plaws thiab cov ntaub ntawv tseem ceeb tshaj plaws-peb cov kws tshaj lij tuaj yeem sau cov ntaub ntawv ceev ceev los ntawm kev nyab xeeb ntawm tus choj lossis txawm nyob deb."
System Integration thiab Data Application
Lub radar flow meter yog kev koom ua ke nrog ntau yam tseem ceeb:
- GPRS/4G Wireless Transmitter: Xa cov ntaub ntawv ceev ceev tam sim ntawd mus rau USGS National Water Information System thiab lub xeev cov chaw tswj xyuas dej.
- Touchscreen Datalogger: Tso cai rau cov neeg ua haujlwm saib xyuas cov ntaub ntawv hauv lub sijhawm tiag tiag, teeb tsa qhov tsis raug, thiab xa tawm cov ntaub ntawv keeb kwm rau kev saib xyuas yooj yim thiab calibration.
- Multi-Parameter Monitoring: Lub kaw lus ib txhij saib xyuas cov dej theem thiab, ua ke nrog cov ntaub ntawv ua ntej calibrated channel cross-section cov ntaub ntawv, cia li xam cov dej tawm hauv lub sijhawm.
Cov ntaub ntawv no yog siv ncaj qha rau:
- Kev Tshawb Fawb Txog Kev Tso Dej: Ua kom raug txheeb xyuas cov dej tso tawm los ntawm Glen Canyon Dam kom ua raws li kev cog lus ntawm kev faib dej ntawm cov xeev qis.
- Cov Qauv Ceeb Toom Txog Dej Nyab: Muab sijhawm ntev dua rau kev ceeb toom dej nyab rau cov zej zog hauv qab.
- Environmental Flow Studies: Pab cov kws tshawb fawb nkag siab txog qhov cuam tshuam ntawm qhov sib txawv ntawm cov dej ntws hauv qab dej, muab cov ntaub ntawv los txhawb cov chaw nyob rau cov ntses uas muaj kev puas tsuaj.
Yav tom ntej Outlook
Qhov kev vam meej ntawm txoj haujlwm no muab tus qauv rau kev txhim kho kev soj ntsuam cov thev naus laus zis ntawm cov chaw tseem ceeb thoob plaws Colorado River Basin thiab thoob plaws Tebchaws Meskas. Cov tub ceev xwm dej hiav txwv npaj yuav nthuav tawm cov thev naus laus zis tsis sib cuag radar no ntawm qhov chaw soj ntsuam tseem ceeb thiab muaj kev phom sij ntau dua li tsib xyoos tom ntej.
"Hauv kev ntsib kev sib tw ntawm kev hloov pauv huab cua, peb yuav tsum siv cov thev naus laus zis tshaj plaws los tswj hwm peb cov peev txheej tseem ceeb tshaj plaws," tus thawj coj ua haujlwm xaus. "Qhov kev nqis peev no tsis yog txhim kho cov ntaub ntawv zoo thiab kev nyab xeeb ntawm cov neeg ua haujlwm nkaus xwb tab sis kuj yog tsim lub hauv paus ruaj khov rau peb cov dej nyab xeeb yav tom ntej."
Ua tiav cov servers thiab software wireless module, txhawb RS485 GPRS / 4g / WIFI / LORA / LORAWAN
