Croatian Experience in Exploitation of Hydrological Calculations in a Road Design Practise

Intensive building of road network started in Croatia in last few years and lots of roads are designed and build yet. Calculations, design and construction of drainage structures are an important part of road construction even not always recognized. There is no doubt that hydrological calculation of drainage constructions are essential elements for complete road design, but still in everyday design very often marginalized. Correct choice of hydrological parameters has an important influence on appropriate functioning of drainage constructions and also there is significant influence on the road economy (maintenance costs etc.) and traffic safety. Present paper gives a brief comparative analysis of precipitation intensities from different Croatian areas, as well as analysis of their practical interpretation. Besides that this paper contains an example analysis for presentation of economic aspect of correct drainage constructions building.
