Abstract
The Drava River, often due to the flow of large quantities of water from its tributary Mura, flooded areas around Koprivnica and Djurdjevac in Podravina for centuries. In the last half century, there have been three floods of catastrophic proportions. The double flood was in 1965, the same scenario repeated in 1966, and the serious damages of the Drava River spills in 1972 remain in the collective memory. At that time, about thirty Podravina settlements were flooded, including parts of Koprivnica, also around 11,000 hectares of agricultural land, and hundreds of residential and commercial buildings and numerous roads and bridges have been destroyed or damaged. The recorded damage was ten times greater than that of previous floods. The devastating floods led to the intensification of the embankment construction, which reduced the danger of flooding, however Drava River had threatened to spill on several occasions afterwards. Final solution for the water management control was the system of Drava hydroelectric power plants, but the projects related to areas of Koprivnica and Djurdjevac in Podravina had not been realized for a number of reasons.
