Sažetak
Earlier studies of alluvial streams in the Region of Međimurje had been very insufficient so these current studies presented the first systematic research. The studies included hydrological, physical‐chemical and faunistic characteristics of two streams. The Bistrec (BI) is larger and much richer in water than Boščak (BO). The average annual flow at the station BI2 was 2.3 m³/sec, and at the station BO2 it was only 0.33 m³/sec. Particularly significant is the difference in electrical conductivity, which in the stream of Bistrec was 677‐777 μS/cm, and it is a result of much higher values of Ca, Mg and sulfate and a slightly higher values of Ni, Pb and nitrite. In the case of the creek of Boščak, the values of electrical conductivity were significantly lower (288‐382  μS/cm) with slighltly higher values of the indicators of organic pollution: COD, Cr, nitrate, total nitrogen and orthophosphate, probably a consequence of intensive agriculture in the basin. The total presence of 66 species of macrozoobenthos have been found. At all stations the most numerous species was Gammarus roeseli (Amphipoda). The only exception was the station BI2 where the smallest number of macrozoobenthos have been registered (1092 Eq./m²), with a significant share of representatives of the Gastropoda groups, which at other stations come sporadically. At other stations the number of macrozoobenthos was in the range of 4100‐5765 units/m². According to the Regulation on water quality standards, it is good ecological quality.
