Water quality in the Dalmatian waters of Southern Croatia was assessed using four different indices: an arithmetic index, arithmetic modified index, geometric modified index, and Solway‐modified index. The waters were sampled 12 times during 1 year (from July 1998 to July 1999) at 50 sampling sites in Dalmatia. Nine water quality parameters were evaluated: temperature, mineralization, corrosion coefficient, dissolved oxygen, biochemical oxygen demand, total nitrogen, protein nitrogen, total phosphorus, and total coliform.
A comparison of the indices showed that the arithmetic modified index and Solway modified index are relatively similar for high‐quality water (i.e., they enable better discrimination between high‐ and low‐quality water). Both indices, however, tend to yield a lower index number for low‐quality waters.
