9.4 POSSIBLE SOLUTIONSIt is possible to diminish the negative impact of the canals on ecology and biodiversity. With respect to theproblems mentioned in paragraph 2 of this chapter, the following solutions are possible (they all need furtherelaboration):1. Diminishing the barrier effect of the canals:− The canals could be covered, so that the number of possible passages for fauna is increased.− The canals could be raised on poles for certain lengths to enable animals to pass underneath thecanals. This also minimizes the disturbance of small streams crossing the canals.− The number of underpasses could be increased by constructing more ducts/culverts under the canals.2. Preventing animals from falling into the canals and drowning:− A more extensive part of the canals could be covered with concrete slabs. There is already ampleexperience with this method, since 2,170 meters have already been covered this way.− The design of the canals could be modified to enable animals that fall in to get out again. Thecanals could be widened on both sides at regular distances and the sides could be made less steepwith a “ladder” profile.− The flow speed of the water could be diminished through the construction of a storage reservoir tocreate buffer capacity directly above the pipeline. This way, the amount of water transported throughthe canals could be maintained at a more constant level.3. Restoring the natural hydrology of the streams downhill from the canals:− Streams should not flow directly into the canals, but instead pass under or over them (for example bythe use of culverts or concrete covers respectively).Photo: Hans BekkerOne of the water canal tracks that is already covered.Mammal survey Serra da Estrela - Portugal 2009 43
