Ecologically acceptable flows definition for the Žrnovnica river (Croatia)

The paper defines an ecologically acceptable flow regime for the River Žrnovnica, Croatia. This is a small and relatively short karst river high flows and high quality water, convenient for use for public water supply. Because the water from the river will be taken from the karst spring zone, the entire river channel could suffer negative ecological consequences. The main goal of setting minimum acceptable flows is to protect the Žrnovnica river food webs and to sustain the rare and endangered fish species Salmothymus abtusirostris. This paper presents result obtained from hydrological, morphological and biological investigations
