Sažetak
In recent years there has been an increasingly frequent occurrence of droughts across the world, including Croatia. For all continuous and complex monitoring of meteorological, hydrological and hydro-geological parameters, drought can neither be anticipated nor predicted, but consequences in its aftermath can be tempered. In Croatia, drought is generally assessed in relation with total annual crop yield. With drought occurrence, crop yield drastically drops. In extremely dry years even in excess of 70%. To that end, construction of irrigation systems is being accelerated. This paper shows calculation of maximum available water quantity for irrigation which can be collected from the Mirna river. The analysis of water requirements showed that in the north-western part of Istrian peninsula irrigation needs for 24.000 ha of agricultural land take in an average year 61×106 m3 of water. In order to secure sufficient water quantity for agricultural land irrigation, it is necessary to construct a system of large accumulations in the analysed area with a total volume of 85×106 m3. The needed water will in part be collected through intakes on the Mirna river, the biggest and most significant water course in Istria. For purpose of assessment of available water quantity for irrigation from the Mirna river, hydrological data were processed. The processing comprises the analysis of average and minimum monthly and annual flows on gauge stations, which defines medium and low water level. In addition to hydrological data, meteorological measurements and catchment elements were in part used, as well. On locations of planned intakes on the Mirna river, the frequency and duration analysis of daily flow determined maximum available pumping quantities while meeting the requirements for environmentally acceptable flow.
