HYDROGEOLOGICAL SIGNIFICANCE OF RECESSION COEFFICIENTS AT THE EXAMPLE OF ISTRIAN SPRINGS

Hydraulic extract of discharge coefficient for the type of schematized karstic aquifer clearly expresses hydrogeological and geometrical parameters on which depends the value of this coefficient and is a very valuable parameter in the identification of groundwater system. On the example of Istrian springs Bula , Gradole and Fonte Gajo discharge coefficient indicates that the drainage area of Gradole spring is multiple times greater than the drainage area of other Istrian springs.
