ODVODNJA U OSJEČKOM KRAJU (19. STOLJEĆE I POČETAK 20. STOLJEĆA)
DRAINAGE IN OSIJEK AREA (19TH CENTURY AND EARLY 20TH CENTURY )

Summary/Abstract: Drainage of Osijek area, alongside Drava river, west of the city Osijek, had been an early water management activity - essential to life and economy of people.Frequent flooding here was due to unregulated water flows of Karašica and Vučica and their affluents, unfavorable location of bridges and watermill dams, neglected and blocked water channels and gutters, as well as treetrunks, lying in water beds due to caving river banks and blocking the flow. Basins and river beds of Karašica and Vučica, due to their insufficient drainage, could not deal with incoming water and infuse into Drava river. Diffused and spilt waters were left inside forests, meadows and fields, long after water-levels returned to normality, having sa devastating effects on economy, households, infrastructure etc. This is why Drava region was early recognized as very attractive for settling down and development of settlements: soil was good for cultivation, both the climate and water system were relatively good, primary vegetation was predominantly woods and prairies, river banks were mainly elevated and steep, there was a solid traffic interconnection other mess and more distant settlements, with plenty of water springs and foods - there was a need for water regulation with embankments and causeways, with regular defense system and maintenance of excess water drainage. However, lower flux of Drava - regulation of water flow by meander cross section, bulwalk building, melioration (drainage through building of channel network) etc. - in general were very slow and disorganized; efficient drainage did not happen until 1898, when Water regulation cooperative for Karašica, Vučica and their affleutns.
