Ukusetshenziswa kwe-Geophysics ekulondolozweni kwamanzi
I-Pendahuluan
Ukongiwa kwamanzi kungenye yezinkinga ezibalulekile zekhulu lama-21 ezibhekene namazwe amaningi emhlabeni jikelele, okuhlanganisa ne-Indonesia. Ukuncipha kwemithombo yamanzi, kanye nokwanda kwesidingo kanye nokushintsha kwesimo sezulu okungalindelekile, kuphoqa ososayensi nabacwaningi ukuthi bathole izindlela ezintsha zokonga nokuphatha amanzi ngendlela esimeme. Enye indlela ethola ukunakwa okwandayo ukusetshenziswa kobuchwepheshe be-geophysical.
Ubuchwepheshe be-geophysical bunikeza amathuba amasha okumaka nokuqonda izinsiza zamanzi angaphansi komhlaba kanye nokuthola izindawo ezisengozini yokuntuleka kwamanzi. Lesi sihloko sizoxoxa ngendlela ukusetshenziswa kwe-geophysical okusetshenziswa ngayo emisebenzini yokonga amanzi, okuhlanganisa ukuhlola kwe-geological, i-hydrogeology, kanye nokusetshenziswa kwezinsimbi ze-geophysical ezithuthukisiwe.
Ukulondolozwa Kwamanzi Nezinselele Zawo
Ukongiwa kwamanzi akugcini nje ekunciphiseni ukusetshenziswa kwamanzi kuphela; kuhilela nokuphathwa kwemithombo yamanzi ephelele. Lokhu kuhlanganisa ukuqapha ikhwalithi yamanzi, ukuvuselela imvelo yasemanzini, kanye nokuvikela imithombo yamanzi angaphansi komhlaba. Njengoba inani labantu emhlabeni wonke likhula, ukukhula kwamadolobha okusheshayo, kanye nezidingo zemikhakha yezolimo neyezimboni, ingcindezi emithonjeni yamanzi iyanda.
Ukutholakala kwedatha enembile kanye nokuqonda okuphelele kwezimo zamanzi angaphansi komhlaba kubalulekile ekwakheni amasu okulondoloza asebenzayo. Yilapho ubuchwepheshe be-geophysical budlala khona indima ebalulekile.
Ubuchwepheshe be-Geophysics ekulondolozweni kwamanzi
1. Ucwaningo Lwezemvelo kanye Nolwemvelo
Ucwaningo lwe-geological kanye ne-hydrogeological luyisisekelo sokuqonda izimo zamanzi angaphansi komhlaba. Amasu esimanje e-geophysical njengezindlela zokuzamazama komhlaba, ukumelana kukagesi, kanye ne-georadar asetshenziswa ukukhiqiza amamephu angaphansi komhlaba anemininingwane. Lawa mamephu ahlinzeka ngolwazi olubalulekile mayelana nezendlalelo zomhlabathi, izakhiwo ze-geological, kanye nokuba khona kwama-aquifer (izendlalelo ezingaphansi komhlaba eziqukethe amanzi).
Indlela Yokuzamazama: Le ndlela ihilela ukulinganisa ijubane lamagagasi okuzamazama asakazeka enhlabathini nasemadwaleni. Ngokuhlaziya idatha yamagagasi okuzamazama komhlaba, abacwaningi bangabona izingqimba zamadwala ezahlukene kanye nokuba khona kwamanzi angaphansi komhlaba okungenzeka.
Ukumelana Nogesi: Amasu okumelana nogesi alinganisa ukumelana kwenhlabathi nokugeleza kukagesi. Amanzi anamaminerali ancibilikisiwe anokumelana okuphansi kunedwala noma inhlabathi eyomile. Ngokumaka ukumelana nenhlabathi, abacwaningi bangabona izindawo ezinemithombo yamanzi engaba khona.
I-Georadar (GPR): I-Georadar isebenzisa amaza kagesi ukuthola izinto ezingaphansi komhlaba. Le ndlela iwusizo kakhulu ekutholeni izingqimba zamanzi angajulile, izakhiwo eziyinkimbinkimbi ze-geological, kanye nokuba khona kokungcola emanzini.
2. Ukuqapha Nokuphatha Amanzi Angaphansi Komhlaba
Ukuphathwa kwamanzi angaphansi komhlaba okuphumelelayo kudinga ukuqapha okuqhubekayo kwamanzi angaphansi komhlaba. Izinzwa ze-Geophysical zisetshenziselwa ukuqapha izinguquko enanini kanye nekhwalithi yamanzi angaphansi komhlaba. Lobu buchwepheshe buhlanganisa ama-piezometer alinganisa umfutho wamanzi, izinzwa zokuqhuba ugesi ezilinganisa usawoti, kanye nobuchwepheshe bokuqapha obusekelwe kwisathelayithi.
Idatha eqoqwe kulezi zinzwa iyahlaziywa ukuze kubikezelwe izinguquko emithonjeni yamanzi. Ngokuqapha ngesikhathi sangempela, izinyathelo zokulondoloza zingathathwa ngokushesha ukuvimbela ukukhishwa ngokweqile noma ukuwohloka kwekhwalithi yamanzi.
3. Ukutholwa Nokunciphisa Ukungcoliswa Kwamanzi
Ukungcoliswa kwamanzi angaphansi komhlaba kuyinkinga enkulu engathinta impilo yabantu kanye nezinhlelo zemvelo. Amasu e-geophysical afana nokuhlolwa kwe-electromagnetic kanye ne-geochemical manje asetshenziswa ukuthola imithombo yokungcola ngaphambi kokuba yonakalise imithombo yamanzi kakhulu.
Ucwaningo Lwe-Electromagnetic: Lolu hlelo lusetshenziselwa ukuthola izinto ezingcolisayo njengezinsimbi ezisindayo ngokusebenzisa amasimu kazibuthe azikhiqizayo. Lolu cwaningo luwusizo kakhulu ekudwebeni amapayipi angcolisayo nokunquma imvelaphi yokungcola.
I-Geochemistry: Ukuhlaziywa kwe-geochemical kwamasampula amanzi kunikeza ulwazi mayelana nokwakheka kwamakhemikhali emanzini. Lokhu kusiza ekuboneni uhlobo lokungcola kanye nobunzima balo, okuvumela ukungenelela ngesikhathi ukuze kuncishiswe imiphumela emibi yako.
4. Ukumodela Kwamanzi
Amamodeli e-hydrological ayithuluzi elibalulekile lokulingisa ukugeleza kwamanzi emhlabathini nokuqonda ukuguquguquka kwamanzi angaphansi komhlaba. Ubuchwepheshe be-geophysical buhlinzeka ngedatha edingekayo ukudala amamodeli anembile, angahlolwa ngokumelene nokushintsha kwesimo sezulu okuhlukahlukene, ukusetshenziswa kwamanzi, kanye nezimo zokuphathwa kwezinsiza.
Le modeli iyasiza ekwenzeni izinqumo ngezinqubomgomo zokongiwa kwamanzi, isibonelo ukunquma izindawo zokuvikela amanzi angaphansi komhlaba, izindawo zokuvuselela amanzi angaphansi komhlaba, kanye nokwenza ngcono ukusetshenziswa kwamanzi kwezolimo kanye nezimboni.
5. Ukuvuselelwa Kwezinhlelo Zemvelo Zamanzi
I-Geophysics isetshenziswa futhi emizamweni yokuvuselela izindawo zemvelo zasemanzini ezonakele, njengemithombo yamanzi emifuleni kanye namanzi angcolile. Amasu e-Geophysical asiza ekudalweni kwamamephu okuvuselela, ukuhlaziywa kokufaneleka komhlaba, kanye nokuthola izindawo ezingase zivuselelwe zibe izindawo zemvelo ezisebenza njengezindawo zokugcina amanzi.
Isibonelo, izindlela zokumelana nogesi zingasetshenziswa ukukala umswakama wenhlabathi futhi zisize ekutholeni izindawo ezifanele zokutshala kabusha izitshalo zemvelo. Lezi zitshalo zizosiza ekugcineni umswakama wenhlabathi futhi zigcwalise amanzi angaphansi komhlaba.
Ucwaningo Lwecala Lokusetshenziswa Kwe-Geophysics Ekongiweni Kwamanzi
Isifundo Secala 1: I-Indonesia
E-Indonesia, izindlela ze-geophysical zisetshenziswe ukumaka izindawo zokugcina amanzi ezindaweni ezomile njenge-East Nusa Tenggara. Ngocwaningo lokumelana nogesi kanye nomodeli wamanzi, abacwaningi bathole imithombo yamanzi ebalulekile engaphansi komhlaba, esetshenziswa kumaphrojekthi okunisela endawo. La maphrojekthi athuthukise ikhwalithi yokuphila emiphakathini eminingi ngokuhlinzeka ngokufinyelela kwamanzi adingekayo kwezolimo nasekusetshenzisweni kwansuku zonke.
Isifundo Secala 2: ICalifornia, e-United States
ICalifornia, eyaziwa ngesomiso sayo esibi kakhulu, isebenzise ubuchwepheshe be-geophysical ekuphathweni kwamanzi angaphansi komhlaba. Izinhlelo zokuqapha ezisekelwe ezinzwa zifakiwe emanzini ahlukahlukene ukuze kuqashwe amazinga amanzi futhi kutholakale ukwehla kwamazinga amanzi angaphansi komhlaba kusenesikhathi. Lolu lwazi lusetshenziswa yiziphathimandla zendawo ukuphatha ukusetshenziswa kwamanzi ngendlela eqhubekayo nokuvimbela ukukhishwa kwamanzi ngokweqile.
Isiphetho
Ukusetshenziswa kobuchwepheshe be-geophysical ekongiweni kwamanzi kunikeza ikhambi eliqondile nelisebenzayo lokuphathwa kwemithombo yamanzi okusimeme. Njengoba benekhono lokumaka nokuqapha izinsiza zamanzi angaphansi komhlaba ngokuningiliziwe, lobu buchwepheshe buyasiza ekubhekaneni nezinselele ezibhekene nokulondolozwa kwamanzi, kusukela ekuphathweni kwamanzi angaphansi komhlaba kuya ekutholakaleni kokungcola kanye nokuvuselelwa kwezinhlelo zemvelo zasemanzini.
Ukusetshenziswa okufanele nokuqhubekayo kwamasu e-geophysical kungadlala indima ebalulekile ekuqinisekiseni izinsiza zamanzi zezizukulwane ezizayo, ukuqinisekisa ukusimama kwemvelo, kanye nokuthuthukisa ikhwalithi yokuphila kwemiphakathi yomhlaba wonke. Ngakho-ke, ubuchwepheshe be-geophysical abuyona nje ithuluzi elibalulekile lesayensi kodwa futhi buyisihluthulelo sokulondoloza enye yezinsiza zemvelo ezibaluleke kakhulu empilweni yabantu: amanzi.
