Hydropedological map of the Republic of Croatia was made at a scale of 1:300,000 as part of the interdisciplinary scientific-technical project aimed at sustainable management of water resources and soil, notably agricultural land. Using pedological and hydropedological data at large and/or semi-detailed scale, data on drainage canal networks, rockiness and land use, hydropedological units were defined according to soil moistening by surface and/or ground water and soil moisture regime to two metres referent depth, as well as priority amelioration units for drainage, dry farming, irrigation, forests and grasslands. Of the overall 30,337.6 km2 of agricultural land and karst wasteland, there are 1,330.8 km2 of priority amelioration units for low-intensity basic drainage, 7,405.1 km2 for basic and detailed pipe drainage, 15,453.1 km2 up to 500 m above sea-level for dry farming or/and irrigation, 2,605.7 km2 from 500 to 1,000 m a.s.l. for dry farming without irrigation, 284.8 km2 above 1,000 m a.s.l. for forests and grasslands, and 3,258.1 km2 of priority units for karst wasteland afforestation. Hydropedological and amelioration units are documented by their pedological and hydropedological characteristics, including infiltration, horizontal water permeability, soil water capacity, groundwater regime, effective precipitation, soil water deficiency, water runoff from the rhizosphere and maximal daily coefficient of precipitation water runoff. All the above data are listed and organized in GIS. Keywords: hydropedology, hydroameliorations, surface and ground water, map, GIS
