Project summary

Edit project overview to modify the project summary.


The river Cabra is under strong agricultural and urban pressure, with a very fragmented landscape whose main uses, are not only urban, but also industrial and agricultural (greenhouses and crops such as olive groves and orchards).Therefore, this upper section of the river suffers from various kinds problems. Among them are the spillings and waste accumulation, the loss of water quality, erosion and destabilization of the riverbed and its banks, a serious degradation of vegetation and the absolute disconnection of the fluvial environment and the urban, agricultural and industrial environment.

Even so, there is a there is still a wealth of flora and fauna in its banks, real and potential, and a public demand for the protection, conservation and enhancement of the natural resources associated with the urban section of the river Cabra, by both the Cabra City Coucil and local citizens associationes. Hence, the project aims to improve the landscape and aesthetics of the area (by cleaning and removal of waste), to restore and improve the natural environment (with silvicultural treatments of riverside vegetation and plantations) and to carry out hydrological recovery actions, such as stabilization of slopes and recovery of margins witch present erosion problems. In this regard, the project proposes planting of autochthonous vegetation (elms, poplars, ashes, willows, tarajes, figs ...) along the most degraded banks. Furthermore, in order to enhance the area’s recreational use, actions have been carried out for the interpretation of nature and conditioning of spaces and infrastructures for public use. Recreational areas integrated into the river space have been built, as well as river paths and promenades, etc.

Reasons for river restoration

Mitigation of a pressure
Hydromorphology Erosion and destabilization of the riverbed and its banks
Biology A serious degradation of vegetation
Physico-chemical Spillings and waste accumulation; Loss of water quality
Other reasons for the project Absolute disconnection of the fluvial environment and the urban, agricultural and industrial environment.


Measures

Structural measures
Bank/bed modifications hydrological recovery actions (stabilization of slopes and recovery of margins witch present erosion problems).
Floodplain / River corridor planting of autochthonous vegetation (elms, poplars, ashes, willows, tarajes, figs ...) along the most degraded banks; silvicultural treatments of riverside vegetation and plantations; cleaning and removal of waste; improve the longitudinal and transverse continuity of the river, extending the width of the banks and creating a fluvial corridor
Planform / Channel pattern
Other recreational use (construction of footpaths, promenades and footbridges, and also recreational areas integrated into the river area, improving the population education and connection with their environmental heritage)
Non-structural measures
Management interventions
Social measures (incl. engagement)
Other
