Water storage bassin with steep sloped dam 
Vetiver protection after only 7 month
This water storage bassin near Velez-Malaga with about 40 million liters capacity has a very steep – almost 1:1 – outside slope. The material is completely loose landfill. To protect this 5 rows of vetiver at a 25 cm spacing have been planted. Ideally it should have been 3 times as many rows. Which the owner did not support.
It was planted very late so the vetiver plants were dormant over the winter and the started to grow in spring.
Progress will be documented in future posts.
