Project summary

Edit project overview to modify the project summary.


The fluvial space has been reduced by the advance of agriculture, infrastructure construction and the possible expansion of industrial estates. Also, improper utilization of public use involves the accumulation of waste. The axis of the Llobregat highway is also source of noise and visual pollution. The main objectives are: creating an artificial wetland; creating a wet meadow (temporary flooding); protection of sand and gravel bars; construction of a longitudinal wall for crop protection.
