Odra. Actions for environmental restoration and flood control in the lower basin of the Odra River (Burgos)
Key features of the case study
The agricultural development of the last decades has modified the Odra fluvial system so deeply, consequently the river planform has changed, also loosing part of its lateral functionality due to the construction of lateral levees, resulting in lower inundability of the floodplain and invasion of the public hydraulic domain in comparison with a reference state. The disapearance of the riparian corridor makes easier the flooding frequency, even though the high flows are not necessarily too high.
Site description
The Odra river is tributary of the Pisuerga by its left margin, flowing through the province of Burgos
Measures selection
The project aimed to compensate the flood protection constructions by improving and creating the riparian vegetation.
the measures include:
- Removal of sediments and waste from the river channel
- Silvicultural treatments (sowing and plantation of native species)
- Morphological recovery at some channel reaches
- Removal of sediments and waste from the river channel
Success criteria

Extra background information
The fertile floodplain is used for irrigation crops, including cultivated beetroot, alfalfa, corn and fruit trees. Also cereal can be found in the lands of the Paramo and formerly the vineyard was very important, but rare actually.
