Ukuqapha okuqhubekayo “kokucindezelwa kwamanzi” kwezitshalo kubaluleke kakhulu ezindaweni ezomile futhi ngokwesiko kuye kwenziwa ngokukala umswakama womhlaba noma ngokusungula amamodeli e-evapotranspiration ukuze kubalwe isamba sokuhwamuka komhlaba kanye nokushintshashintsha kwezitshalo.Kodwa kukhona amandla okwenza ngcono ukusebenza kahle kwamanzi ngobuchwepheshe obusha obuzwakala ngokunembe kakhudlwana lapho izitshalo zidinga ukuchelelwa.
Abacwaningi bakhethe ngokungahleliwe amaqabunga ayisithupha ayevezwe ngokuqondile emthonjeni wokukhanya futhi afaka izinzwa zamaqabunga kuwo, agwema imithambo emikhulu nemiphetho.Baqopha izilinganiso njalo ngemizuzu emihlanu.
Lolu cwaningo lungaholela ekwakhiweni kohlelo lapho izinzwa zokuncinza amaqabunga zithumela ulwazi olunembile lomswakamo wezitshalo endaweni emaphakathi ensimini, ebese ixhumana ngesikhathi sangempela nohlelo lokunisela amanzi ezitshalweni.
Izinguquko zansuku zonke ekujikeni kwamaqabunga bezizincane futhi azikho izinguquko ezibalulekile zansuku zonke ezibonwayo njengoba amazinga omswakama wenhlabathi enyakaza esuka phezulu eya endaweni yokushwabana.Kodwa-ke, lapho umswakama womhlabathi ungaphansi kwendawo yokushwabana, ukuguquka kokuqina kwamaqabunga kwaba sobala kakhulu kwaze kwaba yilapho ukujiya kwamaqabunga kuzinza phakathi nezinsuku ezimbili zokugcina zokuhlolwa lapho umswakama ufinyelela ku-5%. I-Capacitance, ekala ikhono leqabunga lokugcina ukushaja, ihlala icishe ingaguquki okungenani ngezikhathi ezimnyama futhi ikhula ngokushesha phakathi nezikhathi zokukhanya.Lokhu kusho ukuthi umthamo uwukubonakaliswa komsebenzi we-photosynthetic.Uma umswakama wenhlabathi ungaphansi kwendawo yokubola, ukuguquka kwe-diurnal kumthamo kuncipha futhi kuma ngokuphelele lapho umswakama wenhlabathi we-volumetric uwela ngaphansi kuka-11%, okubonisa ukuthi umphumela wokucindezeleka kwamanzi kumthamo ubonwa ngomphumela wawo ku-photosynthesis.
“Ugqinsi lweshidi lufana nebhaluni-iyanda ngenxa ye-hydration kanye nezinkontileka ngenxa yokucindezeleka kwamanzi noma ukuphelelwa amandla kwamanzi,”Kalula nje, umthamo wamaqabunga uyashintsha ngokushintsha kwesimo samanzi sesitshalo kanye nokukhanya okuzungezile.Ngakho-ke, ukuhlaziywa kokuqina kwamaqabunga kanye nezinguquko kumthamo kungabonisa isimo samanzi esitshalweni - umthombo wokucindezela.»
