The project Hydropedological Map of the Republic of Croatia was implemented using the ESRI program package. It includes the Basic Hydropedological Map with the attribute database of hydropedological mapping units, pedological and hydropedological profi les and hydrological and hydropedological parameters. The cartographic attribute database of the Basic Hydropedological Map comprises hydropedological units – types of moistening by surface water and/or ground water. The soil water retention capacity of particular hydropedological units varies from 248 to 635 mm/m, water infiltration into soil ranges from 0.01 to 7.32 m/day, hydraulic conductivity for 1 m soil depth is from 0.01 to 6.84 m/day, and from 0.01 to 15.6 m/day for 2 m depth. Annual effective precipitation of 25% occurrence probability varies from 551 to 2294 mm, and that of 75% occurrence probability is between 272 and 1180 mm. Maximum one-day runoff coefficient in the conditions of different soil texture and different vegetative cover ranges from 0.24 to 0.94 (25% probability) and from 0.02 to 0.89 (75% probability). Water deficit in soils of different texture (25% occurrence probability) varies annually from 0.0 to 513 mm/m, and deficit of 75% occurrence probability varies from 30 to 857 mm/m. Water surplus in soils of different texture (25% occurrence probability) varies annually from 57 do 1686 mm/m, and surplus of 75% occurrence probability ranges from 0.0 to 606 mm/m. The Applied Hydropedological Map of the Republic of Croatia comprises priority amelioration units for agricultural land reclamation and management.
