Hydrological measurements in Crveno Jezero (Red Lake) in the period from 28 September 2013 to 10 September 2015

Abstract

U članku su analizirani rezultati hidroloških mjerenja izvršenih na Crvenom jezeru kod Imotskog u razdoblju od 28. rujna 2013. u 23 sata do 10. rujna 2015. u 16 sati. U tom su razdoblju kontinuirano (svaki sat) mjereni: (1) vodostaj; (2) temperatura vode; (3) električna vodljivost. Mjerenja su izvršena instrumentom CTD DIVER (Schlumberger Water Services). Instrument je bio postavljen na nadmorskoj visini 212,60 m n.m. tako da su mjerenja vršena stalno u jednoj točki. Tako izvršena i u ovom radu prikazana mjerenja predstavljaju prvi sustavni, kontinuirani monitoring izvršen na ovom svjetski poznatom krškom fenomenu. U radu su definirane vrijednosti promjene zapremine vode u Crvenom jezeru. Izvršene su usporedbe s mjerenjima istih parametara u Modrom jezeru.The paper analyses the results of hydrological measurements carried out in Crveno Jezero at Imotski in the period from 28 September 2013 (11 pm) to 10 September 2015. In this time period, the following parameters were continuously measured (every hour): (1) water levels, (2) water temperature and (3) electrical conductivity. The measurements were performed by using a CTD DIVER (Schlumberger Water Services). The instrument was posi¬tioned at 212.60 m a.s.l. to facilitate continuous measurements in one point. The resulting measurements described in the paper present the first systemic, continuous monitoring conducted in this world-known karst phenomenon. The paper determines the values related to the changes in Crveno Jezero water volumes and compares them with the measurements of the same parameters in Modro Jezero (Blue Lake)
