| During 30 and 31 July and 1 and 2 August 2007, the Canarian several towns were affected by a huge forest fire that burned down a remarkable part of the forests of Pinus canariensis. The total surface burned was over 18,000 ha. The mixture dykes were conceived in early 2008, during actions to control the onset of erosion processes in Teide National Park subsequent to the forest fire. Besides this, rocks are placed on both sides of the dyke. The vertical elements are tied to each other by means of a biodegradable rope and the extremes of the dyke are anchored to the ground or to any adjacent tree or bush. Usual calculations of wooden structures and hydrology were used. The matrix formed by the fine residues creates a fertilized substrate that, as time goes by, is colonized by indigenous species. The sediment wedges caused by the cross barriers turn into a series of green islands throughout the gullies. The body of this dyke is permeable and because of this the water flows through its body, but in a controlled way. This dyke is a temporary structure because its core will mineralize in a few years (from 5-10 depending on the size of the forestry residues used). After a 7 year monitoring work some conclusions can be arisen. Both sedimentation wedges and soil and plant densities were measured. With the collected data the performance of this technique can be already characterised | |
