Abstract

Sliv izvora Gradole nalazi se na Istarskom poluotoku i pripada porječju rijeke Mirne. U slivu
izvora Gradole nalaze se dvije osnovne grupe stijena različitih hidrogeoloških značajki, to su
vodopropusne karbonatne stijene i vodonepropusne klastične stijene. Ukupna površina sliva
iznosi 159,5 km2, a od cijele te površine 85% zauzimaju karbonatne stijene, a 15% pripada
flišnim naslagama. Po svojoj izdašnosti u sušnom razdoblju, izvor Gradole je najveći izvor na
području cijelog Istarskog poluotoka. Crpljenje izvora Gradole značajno se povećava u
ljetnim mjesecima, dok je u ostalim mjesecima približno konstantno. Obradom podataka za
razdoblje od 01.01.2000. do 31.12.2006. godine, utvrđeno je da količina preljeva ovisi o
oborinama i o količini crpljenja. Visina vode iznad kote preljeva niža je što su oborine manje i
što je količina crpljenja veća, a to je posebno izraženo u ljetnim mjesecima zbog veće potrebe
za vodom. Recesijskom analizom prognozirana je izdašnost nakon dužeg sušnog perioda.

Abstract: The catchement of the Gradola spring is located on the Istrian peninsula and it belongs to the
catchement of the river Mirna. In the Gradola spring catchement two basic groups of rock
with different hidrogeological features can be found, and those are the permeability carbonate
rocks and impermeability clastic rocks. The total surface of the catchement is 159,5 km2 and
from that whole surface 85 % are carbonate rocks, while 15 % are flysch deposits. By its
discharge in the dry period, the Gradola spring is the biggest spring on the entire Istrian
peninsula. The pumping of the Gradola spring significantly increases in the summer months,
while it remains fairly constant in the other months. By analyzing the data from 01.01.2000.
until 31.12.2006., it is determined that the quantity of overflow depends on the precipitation
and the pumping volume.The height of the water above the overflow elevation lowers as the
precipitation decreases and the pumping volume rises, which is especially significant during
the summer months due to the higher water demand. By recession analysis the discharge after
a prolonged dry period is predicted.
