The Topčider River has a catchment area of 148 km2, which extends into several Belgrade suburbs. The valley of this river hosts the Belgrade-Mladenovac Highway and railroad lines running from Belgrade to Bar, to Niš and Skopje, and to Smederevo, Požarevac, Majdanpek and Bor.
The torrential nature of a number of streams, and their insufficiently developed channels, lead to frequent flooding and threaten residential areas, infrastructures, and farmland.

Some catchment area development work had already been undertaken but completion remained at the planning stage for some 30 years. 

 

In order to move ahead, a master plan was prepared for the training of small streams, including the Brđanski, Duboki, Kovinski and several other creeks.

 your description

The main goals of the training of the Topčider River tributaries were to:

  • Protect residential areas from flash flooding; and
  • Protect roads and railroads from flash flooding (most importantly, the main railroad line from Belgrade to Niš).

Additional benefits included:

  • Mitigation of flood damage to farmland;
  • The use of water from small reservoirs for drinking water supply and irrigation;
  • The use of small reservoirs for tourism;
  • The discharge of water from reservoirs during the summer to improve downstream water quality.


In addition to addressing the above aspects, the master plan project included extensive investigations and data collection (surveys of potential reservoir and dam locations, exploratory boring and geomechanical laboratory tests).
Seventeen potential sites were identified and assessed, and four locations were selected and proposed for the erection of four dams and the formation of three small reservoirs and one retention pond.

The main features of these facilities are:

  • Multi-purpose reservoirs, to ensure efficient use of the area and water resources;
  • Homogeneous earthfill (clay) dams;
  • All dams classified as low (H < 15 m);
  • Water levels in the reservoirs and the retention pond will reach the overflow crest only in the event of a flood wave whose return period is 1:1000 years.

The overall project cost, including four dams, three reservoirs, and one retention pond, is currently estimated at 1,412,920€.
