Abstract

U završnom radu analizirana je potreba za navodnjavanjem vinove loze za prosječne klimatske i pedološke uvjete Vrbničkog polja (otok Krk) koristeći program CROPWAT. Osim potrebe za navodnjavanjem s obzirom na prosječne klimatske pokazatelje, u radu su analizirani i budući scenariji klimatskih promjena (SSP2 4.5 i SSP5 8.5 scenariji). SSP2 4.5 scenarij predviđa porast temperature za 1.6°C. Scenarij SSP5 8.5 s druge strane predviđa porast temperature za 2,5°C . Uz smanjenje temperature izračun potreba za navodnjavanjem temeljio se i na smanjenju oborina za 15 odnosno 20 % u odnosu na višegodišnji prosjek za najbližu meteorološku postaju.
Rezultati rada pokazali su da u prosječnoj klimatskoj godini, kao i u scenarijima SSP2 4.5 i SSP5 8.5, najveći deficit vode javlja se u mjesecu srpnju te je u tom mjesecu najveća potreba za navodnjavanjem. Konkretno, u prosječnoj klimatskoj godini potrebno je dodati 112 mm vode, u scenariju SSP2 4.5 potrebno je dodati 115,3 mm, dok je u scenariju SSP5 8,5 potrebno dodati 121,6 mm.

Abstract (english)

In this undergraduate thesis project the need for irrigation of grapevines under the average climatic and soil conditions of the Vrbničko polje (island of Krk) was analyzed using the CROPWAT program. In addition to the need for irrigation regarding average climate indicators, the paper also analyzed future climate change scenarios (SSP2 4.5 and SSP5 8.5 scenarios). The SSP2 4.5 scenario predicts a temperature rise of 1.6°C. The SSP5 8.5 scenario, on the other hand, predicts a temperature increase of 2.5°C. In addition to the decrease in temperature, the calculation of irrigation needs was also based on a decrease in precipitation by 15 or 20 % compared to the multi-year average for the nearest meteorological station.
The results of the work showed that in an average climatic year, as well as in the SSP2 4.5 and SSP5 8.5 scenarios, the largest water deficit occurs in the month of July, and the greatest need for irrigation is in that month. Specifically, in an average climate year, 112 mm of water needs to be added, in the SSP2 4.5 scenario, 115.3 mm needs to be added, while in the SSP5 8.5 scenario, 121.6 mm needs to be added.
