Kuhira mu buhinzi bigizwe n’ibirenga 70% by’amazi meza akurwa ku isi, ariko ikoreshwa ry’amazi ritameze neza—riterwa no gukekeranya, kugenzura bishaje, no gukwirakwiza amazi mu buryo budahuje—bituma amazi apfa ubusa buri mwaka. Uko ibura ry’amazi rigenda rirushaho kwiyongera, abahinzi n’abayobozi b’ubuhinzi bakeneye ibikoresho byo gukurikirana, kunoza, no kugabanya ikoreshwa ry’amazi yo kuhira. Ibipimo by’amazi bifunguye, byagenewe gupima amazi atembera mu miyoboro idafunze (urugero, imiyoboro, imiyoboro, n’imiyoboro yo kuhira) bikunze kugaragara mu buhinzi, byagaragaye nk'igisubizo cy’ingenzi cyo kunoza uburyo amazi akoreshwa mu buhinzi abungabungwa. Binyuze mu gutanga amakuru nyayo kandi ajyanye n’amazi nyayo, ibi bipimo bihindura uburyo bwo kuhira “buhumyi” mu buryo bushingiye ku makuru, bigabanya imyanda mu gihe birinda umusaruro w’ibihingwa.
Ikibazo cyo kuhira amazi adakurikiranwe
Guhira mu buhinzi gakondo akenshi bishingiye ku bipimo ngenderwaho: abahinzi bashobora kuhira imirima bitewe n'igihe (urugero, "gukoresha umuyoboro w'amazi amasaha 2") cyangwa ibimenyetso bigaragara (urugero, "gutegereza kugeza ubutaka bumaze kumera neza"), aho gukoresha amazi nyayo cyangwa amazi y'ibihingwa. Ibi bitera ibibazo bibiri by'ingenzi:
- Kuhira cyane: Batazi neza uko amazi anyura, abahinzi bakunze gukoresha amazi menshi kurusha ayo imyaka ikura. Amazi arenze urugero akura mu butaka, agapfusha ubusa ingufu (zo kuvoma), kandi agakuraho amasoko y'amazi meza yo mu gace runaka (urugero: amazi yo mu mazi cyangwa imigezi).
- Ikwirakwizwa ry’amazi ritangana: Mu buryo bunini bwo kuhira, amazi adakurikiranwe ashobora gutuma imirima imwe ibona amazi menshi cyane mu gihe indi ibona make cyane—byangiza umusaruro no gupfusha ubusa umutungo.
Urugero, umuhinzi ukoresha umuyoboro udafite igenzura ashobora kutamenya ko igice cyafunzwe kigabanya amazi ajya mu murima umwe, bigatuma akoresha uburyo bwo kugabanya amazi—akinjira mu wundi murima atabishaka. Ibipimo by'amazi bifunguye bikemura ibi mu gupima amazi, bigakuraho gukekeranya.
Uburyo Ibipimo by'Umuyoboro Ufunguye Bitwara Ibigega Birinda Ubukungu
Ibipimo by'amazi bikoresha ikoranabuhanga nka ultrasound, radar, cyangwa weir/flume systems kugira ngo bipime amazi atembera mu miyoboro idakoresha umuvuduko—bikwiriye cyane ibikorwa remezo byo kuhira abahinzi basanzwe bakoresha. Ingaruka zabyo ku kubungabunga ibidukikije ziri mu bice bitatu by'ingenzi:
1. Gupima neza amazi yo kuhira mu gihe cyo kuhira "ingano ikwiye"
Ibi bipimo bitanga amakuru nyayo ku ngano y'amazi yinjira muri buri muyoboro cyangwa mu murima. Abahinzi bashobora guhuza igipimo cy'amazi aturuka mu murima n'ibikenewe mu buhinzi: urugero, ibigori bikiri bito bishobora gukenera litiro 50 ku munota kuri hegitari, mu gihe ingano zikuze zikenera litiro 30 gusa. Mu gushyiraho ibipimo by'amazi aturuka mu murima kugira ngo bitange amakuru niba igipimo kirenze cyangwa kikagabanuka munsi y'icyerekezo cy'umushinga, abahinzi birinda kuhira cyane kandi bakareba neza ko imyaka ibona ibyo bakeneye neza. Ubushakashatsi bwerekana ko ubu buryo bushobora kugabanya ikoreshwa ry'amazi yo kuhira ho 15-30% bitagabanyije umusaruro.
2. Gutahura imyanda iva mu mazi no kuyifunga kugira ngo imyanda ihagarare
Imiyoboro n'imiyoboro yo kuhira akenshi bivamo imyanda, imiyoboro cyangwa ifunga—ibibazo bitagaragara bitagenzurwa. Ibipimo by'amazi bifunguye bigaragaza ko amazi agwa mu mwobo mu buryo butunguranye bishobora kugaragaza ko amazi yagwa mu mwobo (urugero: imyanda iri mu mwobo), mu gihe ukwiyongera gutunguranye bishobora kugaragaza ko amazi yagwa mu mwobo (urugero: imiyoboro yagwa mu mwobo). Mu gufata ibi bibazo hakiri kare, abahinzi bakemura ibibazo vuba, birinda ko litiro ibihumbi by'amazi yapfa ubusa. Urugero, amazi make mu mwobo ashobora gupfusha ubusa litiro zigera ku 10.000 ku munsi—ikintu icyuma gipima amazi cyamenya mu masaha make.
3. Gukurikirana amakuru kugira ngo akore neza igihe kirekire
Ibipimo byinshi bigezweho by’amazi bifunguye bibika amakuru y’amateka (urugero: amazi yose ya buri munsi cyangwa buri cyumweru) kandi bigahuzwa n’amabaraza yoroshye. Abahinzi bashobora gusesengura aya makuru kugira ngo bamenye imiterere: “Ese Field A ikoresha amazi menshi ku wa Mbere?” cyangwa “Ese inkubi y’umuyaga yo mu kwezi gushize yatugabanyirije icyifuzo cyacu cyo kuhira?” Uko igihe kigenda gihita, aya makuru afasha kunoza gahunda zo kuhira—urugero, kugabanya amazi menshi mu bihe by’imvura cyangwa guhindura ingano y’amazi uko imyaka yeze. Binashyigikira kubahiriza amabwiriza y’amazi yo mu gace, atuma abahinzi barushaho gukurikirana no gutanga raporo ku ikoreshwa ry’amazi.
Ingaruka ku Isi Nyayo: Urugero ku Mirima Mito
Ndetse n'abahinzi bato bungukirwa n'ibipimo by'amazi bifunguye. Mu turere nka Leta Zunze Ubumwe za Amerika cyangwa Punjab mu Buhinde, aho amazi yo mu butaka arimo kugabanuka cyane, abahinzi bakoresha ibi bipimo bavuze ko bazigama amazi menshi. Urugero, umurima wo muri Nebraska washyizeho ibipimo by'amazi bifunguye bikoresha ikoranabuhanga mu miyoboro yawo yo kuhira, kandi wagabanyije ikoreshwa ry'amazi ku kigero cya 22% mu gihembwe kimwe cy'ihinga—bikaba byarazigamye amafaranga ku kiguzi cyo kuvoma mu gihe cyo kubungabunga Ogallala Aquifer. Mu Buhinde, amashyirahamwe yo kuhira mu matsinda akoresha ibipimo by'amazi kugira ngo agabanye amazi mu buryo bungana hagati y'abahinzi, bigabanye amakimbirane kandi bigagabanya imyanda muri rusange ku kigero cya 18%.
Umwanzuro
Ibipimo by'amazi bifunguye si ibikoresho byo gupima gusa—ni imbarutso y'ubuhinzi burambye. Mu guhindura uburyo bwo kuhira budasobanutse mu gufata ibyemezo bihamye, bishingiye ku makuru, bigabanya imyanda y'amazi, bikarinda umutungo w'amazi meza, kandi bikagenzura ko ibihingwa bibona amazi bikenewe kugira ngo bikure neza. Uko ibura ry'amazi ku isi rigenda rirushaho kwiyongera, ibi bipimo bizaba igikoresho cy'ingenzi ku bahinzi biyemeje kuringaniza umusaruro no kubungabunga—kugira ngo babone ibiribwa n'amazi y'ejo hazaza mu bisekuruza.
