Identification of the rainfall impact on the abundance of Rakovac spring using methods of correlation, regression and cross-correlation : master's thesis

U ovom diplomskom radu istražuje se utjecaj oborina na izdašnost izvora Rakovac. Izvor Rakovac smješten je u sjeverozapadnom dijelu Republike Hrvatske i nalazi se u blizini mjesta Koretići na području Žumberačke gore. Pri obradi podataka korišteni su podaci Državnog hidrometeorološkog zavoda o oborinama sa kišomjernih postaja Mrzlo Polje Žumberačko i Rude, te podaci o izdašnosti izvora Rakovac određeni pomoću pravokutnog oštrobridnog preljeva u razdoblju od studenog 2018. do lipnja 2019. godine. Za provedbu analize koristile su se tri statističke metode: korelacija, regresija i kroskorelacija.This thesis examines the impact of rainfall on the abundance of Rakovac spring. Spring Rakovac is located in the northwestern part of the Republic of Croatia and is located near the village Koretić in the area of Žumberačka gora. Analysed data is from the State Hydrometeorological Institute on precipitation from rainfall stations Mrzlo Polje Žumberačko and Rude and they were used in the data processing, as well as data on the abundance of the Rakovac source determined using a rectangular sharp-flow overflow in the period November 2018 to June 2019. Three statistical methods were used to perform the analysis: correlation, regression and cross-correlation
